A multiwavelength investigation of the HII region S311: Young stellar population and star formation
Ram Kesh Yadav, A. K. Pandey, Saurabh Sharma +9
We present a multiwavelength investigation of the young stellar population and star formation activities around the \hii region Sharpless 311. Using our deep near-infrared observat…
A multi-wavelength study of star formation activity in the S235 complex
L. K. Dewangan, D. K. Ojha, A. Luna +4
We have carried out an extensive multi-wavelength study to investigate the star formation process in the S235 complex. The S235 complex has a sphere-like shell appearance at wavele…
Sh2-138: Physical environment around a small cluster of massive stars
T. Baug, D. K. Ojha, L. K. Dewangan +4
We present a multi-wavelength study of the Sh2-138, a Galactic compact H II region. The data comprise of optical and near-infrared (NIR) photometric and spectroscopic observations…
Physical environment of massive star-forming region W42
L. K. Dewangan, A. Luna, D. K. Ojha +3
We present an analysis of multi-wavelength observations from various datasets and Galactic plane surveys to study the star formation process in the W42 complex. A bipolar appearanc…
Study of morphology and stellar content of the Galactic HII region IRAS 16148-5011
K. K. Mallick, D. K. Ojha, M. Tamura +3
An investigation of the IRAS 16148-5011 region - a cluster at a distance of 3.6 kpc - is presented here, carried out using multiwavelength data in near-infrared (NIR) from the 1.4m…
Star formation around the mid-infrared bubble CN 148
L. K. Dewangan, D. K. Ojha, J. M. C. Grave +1
We present a multi-wavelength study to analyse the star formation process associated with the mid-infrared bubble CN 148 (H II region G10.3-0.1), which harbors an O5V-O6V star. The…
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…
W40 region in the Gould Belt : An embedded cluster and H II region at the junction of filaments
K. K. Mallick, M. S. N. Kumar, D. K. Ojha +3
We present a multiwavelength study of W40 star-forming region using IR observations in UKIRT JHK bands, Spitzer IRAC bands & Herschel PACS bands; 2.12 micron H2 narrow-band imaging…
Re-appearance of McNeil's nebula (V1647 Orionis) and its outburst environment
J. P. Ninan, D. K. Ojha, B. C. Bhatt +5
We present a detailed study of McNeil's nebula (V1647 Ori) in its ongoing outburst phase starting from September 2008 to March 2013. Our 124 nights of photometric observations were…
Star formation activity in the Galactic H II region Sh2-297
K. K. Mallick, D. K. Ojha, M. R. Samal +5
We present a multiwavelength study of the Galactic H II region Sh2-297, located in Canis Major OB1 complex. Optical spectroscopic observations are used to constrain the spectral ty…
The outburst and nature of young eruptive low mass stars in dark clouds
J. P. Ninan, D. K. Ojha, B. C. Bhatt +5
The FU Orionis (FUor) or EX Orionis (EXor) phenomenon has attracted increasing attention in recent years and is now accepted as a crucial element in the early evolution of low-mass…
