NGC 7538 : Multiwavelength Study of Stellar Cluster Regions associated with IRS 1-3 and IRS 9 sources
K. K. Mallick, D. K. Ojha, M. Tamura +7
We present deep and high-resolution (FWHM ~ 0.4 arcsec) near-infrared (NIR) imaging observations of the NGC 7538 IRS 1-3 region (in JHK bands), and IRS 9 region (in HK bands) using…
Young Stellar Population of the Bright-Rimmed Clouds BRC 5, BRC 7 and BRC 39
Neelam Panwar, W. P. Chen, A. K. Pandey +5
Bright-rimmed clouds (BRCs), illuminated and shaped by nearby OB stars, are potential sites of recent/ongoing star formation. Here we present an optical and infrared photometric st…
Deep optical survey of the stellar content of Sh2-311 region
Ram Kesh Yadav, A. K. Pandey, Saurabh Sharma +6
The stellar content in and around Sh2-311 region have been studied using the deep optical observations as well as near-infrared (NIR) data from 2MASS. The region contains three clu…
Main-sequence variable stars in young open cluster NGC 1893
Sneh Lata, Ram Kesh Yadav, A. K. Pandey +5
In this paper we present time series photometry of 104 variable stars in the cluster region NGC 1893. The association of the present variable candidates to the cluster NGC 1893 has…
The molecular complex associated with the Galactic HII region Sh2-90: a possible site of triggered star formation
M. R. Samal, A. Zavagno, L. Deharveng +6
We investigate the star formation activity in the molecular complex associated with the Galactic HII region Sh2-90, using radio-continuum maps obtained at 1280 MHz and 610 MHz, Her…
Characterization of the Praesepe Star Cluster by Photometry and Proper Motions with 2MASS, PPMXL, and Pan-STARRS
P. F. Wang, W. P. Chen, C. C. Lin +31
Membership identification is the first step to determine the properties of a star cluster. Low-mass members in particular could be used to trace the dynamical history, such as mass…
