  Star clusters are superb astrophysical laboratories containing cospatial and coeval samples of stars with similar chemical composition. We initiate the Sejong Open cluster Survey (SOS) - a project dedicated to providing homogeneous photometry of a large number of open clusters in the SAAO Johnson-Cousins' UBVI system. To achieve our main goal, we pay much attention to the observation of standard stars in order to reproduce the SAAO standard system.

  More info

  We investigate the young stellar objects (YSOs) in the Lynds 1641 (L1641) cloud using multi-wavelength data including Spitzer, WISE, the Two Micron All Sky Survey, and XMM covering similar to 1390 YSOs across a range of evolutionary stages. In addition, we targeted a sub-sample of YSOs for optical spectroscopy with the MMT/Hectospec and the MMT/Hectochelle. We use these data, along with archival photometric data, to derive spectral types, extinction values, masses, ages, and accretion rates. We obtain a disk fraction of similar to 50% in L1641. The disk frequency is almost constant as a function of stellar mass with a slight peak at log(M-*/M-circle dot) approximate to -0.25. The analysis of multi-epoch spectroscopic data indicates that the accretion variability of YSOs cannot explain the two orders of magnitude of scatter for YSOs with similar masses. Forty-six new transition disk (TD) objects are confirmed in this work, and we find that the fraction of accreting TDs is lower than for optically thick disks (40%-45% versus 77%-79%, respectively). We confirm our previous result that the accreting TDs have a median accretion rate similar to normal optically thick disks. We confirm that two star formation modes (isolated versus clustered) exist in L1641. We find that the diskless YSOs are statistically older than the YSOs with optically thick disks and the TD objects have a median age that is intermediate between those of the other two populations. We tentatively study the star formation history in L1641 based on the age distribution and find that star formation started to be active 2-3 Myr ago.

  More info

  In this paper, an extensive survey of the star-forming complex Sh2-252 has been undertaken with an aim to explore its hidden young stellar population as well as to understand the structure and star formation history for the first time. This complex is composed of five prominent embedded clusters associated with the subregions A, C, E, NGC 2175s and Teu 136. We used Two Micron All Sky Survey-near-infrared and Spitzer-Infrared Array Camera, Multiband Imaging Photometer for Spitzer photometry to identify and classify the young stellar objects (YSOs) by their infrared (IR) excess emission. Using the IR colour-colour criteria, we identified 577 YSOs, of which, 163 are Class I, 400 are Class II and 14 are transition disc YSOs, suggesting a moderately rich number of YSOs in this complex. Spatial distribution of the candidate YSOs shows that they are mostly clustered around the subregions in the western half of the complex, suggesting enhanced star formation activity towards its west. Using the spectral energy distribution and optical colour-magnitude diagram-based age analyses, we derived probable evolutionary status of the subregions of Sh2-252. Our analysis shows that the region A is the youngest (similar to 0.5 Myr), the regions B, C and E are of similar evolutionary stage (similar to 1-2 Myr) and the clusters NGC 2175s and Teu 136 are slightly evolved (similar to 2-3 Myr). Morphology of the region in the 1.1 mm map shows a semicircular shaped molecular shell composed of several clumps and YSOs bordering the western ionization front of Sh2-252. Our analyses suggest that next generation star formation is currently under way along this border and that possibly fragmentation of the matter collected during the expansion of the H ii region as one of the major processes is responsible for such stars. We observed the densest concentration of YSOs (mostly Class I, similar to 0.5 Myr) at the western outskirts of the complex, within a molecular clump associated with water and methanol masers and we suggest that it is indeed a site of cluster formation at a very early evolutionary stage, sandwiched between the two relatively evolved CH ii regions A and B.

  More info

  UBVI CCD photometry of NGC 2353 is performed as a part of the "Sejong Open cluster Survey" (SOS). Using photometric membership criteria we selelct probable members of the cluster. We derive the reddening and distance to the cluster, i.e., E(B - V) = 0.10 +/- 0.02 mag and 1.17 +/- 0.04 kpc, respectively. We find that the projected distribution of the probable members on the sky is elliptical in shape rather than circular. The age of the cluster is estimated to be log(age)=8.1 +/- 0.1 in years, older than what was found in previous studies. The minimum value of binary fraction is estimated to be about 48 +/- 5 percent from a Gaussian function fit to the distribution of the distance moduli of the photometric members. Finally, we also obtain the luminosity function and the initial mass function (IMF) of the probable cluster members. The slope of the IMF is Gamma = -1.3 +/- 0.2.

  More info

  IC 1848 is one of the young open clusters in the giant star-formingCas OB6association. Several interesting aspects relating to star formation processes in giant star-forming regions attracted us to study the initial mass function (IMF), star formation mode and properties of pre-mains-equence (PMS) stars. A UBVI and H alpha photometric study of the young open cluster IC 1848 was conducted as part of the 'Sejong Open Cluster Survey'. We have selected 105 earlytype members from photometric diagrams. Their mean reddening is < E(B -V)> = 0.660 +/- 0.054 mag. Using the published photometric data with near-and mid-infrared archival data we confirmed the normal reddening law (R-V = 3.1) towards the cluster (IC 1848). A careful zero-age main-sequence fitting gives a distance modulus of V-0 - M-V = 11.7 +/- 0.2mag, equivalent to 2.2 +/- 0.2 kpc. H alpha photometry and the list of young stellar objects identified by Koenig et al. permitted us to select a large number of PMS stars comprising 196 H alpha emission stars, 35 H alpha emission candidates, 5 Class I, 368 Class II and 24 transition disc candidates. From the Hertzsprung-Russell diagram using stellar evolution models, we estimate an age of 5 Myr from several evolved stars and 3 Myr from the PMS stars. The IMF was derived from stars with mass larger than 3M(circle dot), and the slope is slightly steeper (Gamma = -1.6 +/- 0.2) than the Salpeter/Kroupa IMF. Finally, we estimated the mass accretion rate of PMS stars with an ultraviolet excess. The mean mass accretion rate is about 1.4 x 10-8M(circle dot) yr(-1) in the mass range of 0.5-2M(circle dot), whereas intermediate-mass stars (>= 2.5M(circle dot)) exhibit a much higher accretion rate of M > 10(-6)M(circle dot)yr(-1).

  Are Debris Disks and Massive Planets Correlated

  . The Astrophysical Journal, 658(2), 1312-1321. doi:10.1086/511746
  More info

  Using data from the Spitzer Space Telescope Legacy Science Program Formation and Evolution of Planetary Systems (FEPS), we have searched for debris disks around nine FGK stars (2-10 Gyr), known from radial velocity (RV) studies to have one or more massive planets. Only one of the sources, HD 38529, has excess emission above the stellar photosphere; at 70 μm the signal-to-noise ratio in the excess is 4.7, while at λ < 30 μm there is no evidence of excess. The remaining sources show no excesses at any Spitzer wavelengths. Applying survival tests to the FEPS sample and the results for the FGK survey recently published in Bryden et al., we do not find a significant correlation between the frequency and properties of debris disks and the presence of close-in planets. We discuss possible reasons for the lack of a correlation.

  We report Spitzer Space Telescope IRAC 3.6, 4.5, 5.8 and 8 um and MIPS 24 and70 um observations of the 32 Ori Group, a recently discovered nearby stellarassociation situated towards northern Orion. The proximity of the group (~93pc) has enabled a sensitive search for circumstellar dust around group members,and its age (~20 Myr) corresponds roughly to an epoch thought to be importantfor terrestrial planet formation in our own solar system. We quantify infraredexcess emission due to circumstellar dust among group members, utilizingavailable optical (e.g. Hipparcos, Tycho) and near-IR (2MASS) photometry inaddition to the Spitzer IR photometry. We report 4 out of the 14 objects whichexhibit 24 um excess emission more than 4\sigma above the stellar photosphere(>20%) though lacking excess emission at shorter wavelengths: HD 35656 (A0Vn),HD 36338 (F4.5), RX J0520.5+0616 (K3), and HD 35499 (F4). Two objects (HD 35656and RX J0520.0+0612) have 70 um excesses, although the latter lacks 24 umexcess emission. The 24 um disk fraction of this group is 29(+14,-9%), which issimilar to previous findings for groups of comparable ages and places 32 Ori asthe young stellar group with the 2nd most abundant 24 um excesses among groupslacking accreting T Tauri stars (behind only the approximately coeval Beta PicMoving Group). We also model the infrared excess emission using circumstellardust disk models, placing constraints on disk parameters including L_IR/L_*,T_disk, characteristic grain distance, and emitting area. The L_IR/L_* valuesfor all the stars can be reasonably explained by steady state disk evolution.[Journal_ref: ]
