J/BaltA/17/1  Infrared photometry in GL490 star-forming region (Straizys+ 2008)

Young stars in the Camelopardalis dust and molecular clouds. III. The GL490 region. Straizys V., Laugalys V. <Baltic Astron. 17, 1-19 (2008)> =2008BaltA..17....1S
ADC_Keywords: Clusters, open ; Photometry, infrared Keywords: stars: formation - stars: pre-main sequence - infrared: stars - ISM: dust, extinction, clouds - Galaxy: open clusters and associations: individual (Cam OB1) Abstract: Using the infrared photometry data extracted from the 2MASS, IRAS and MSX databases, 50 suspected young stellar objects (YSOs) are selected from about 37500 infrared objects in the 3x3deg2 area with the center at (l,b=142.5,+1.0), in the vicinity of the young stellar object GL 490 in the dark cloud T 942 (Dobashi et al., 2005PASJ...57S...1D, Cat. VII/244). The spectral energy distributions between 700nm and 100um suggest that most of the selected objects may be YSOs of classes I and II. In the color-magnitude diagram Ks vs. H-Ks the suspected YSOs occupy an area right of the main sequence what can be interpreted as being caused by the effects of luminosity, interstellar and circumstellar reddening and infrared thermal emission in circumstellar envelopes and disks.

Note (1): Note for individual stars as follows: SL 149 = binary, in K brighter component at 6" SL 162 = binary, in K fainter component at 6" SL 164 = no object in R and very faint in K. Wrong coordinates? SL 165 = in R with tail, in K no tail SL 167 = nearby YSOs separated by 19" SL 168 = nearby YSOs separated by 19" SL 174 = very faint in R and K. Wrong coordinates and IRAS identification? SL 175 = probably heavily reddened Herbig Ae/Be star (in the J-H vs. H-Ks diagram they lie well below the intrinsic T Tauri line) SL 176 = probably heavily reddened Herbig Ae/Be star (in the J-H vs. H-Ks diagram they lie well below the intrinsic T Tauri line) SL 183 = probably heavily reddened Herbig Ae/Be star (in the J-H vs. H-Ks diagram they lie well below the intrinsic T Tauri line) SL 181 = binary, in K fainter component at 10" SL 185 = binary, in K fainter component at 12"-------------------------------------------------------------------------------- Byte-by-byte Description of file: table2.dat
