Optical photometric and polarimetric investigation of NGC 1931
A. K. Pandey, C. Eswaraiah, Saurabh Sharma +7
We present optical photometric and polarimetric observations of stars towards NGC 1931 with the aim to derive the cluster parameters such as distance, reddening, age and luminosity…
Optical and Near-infrared survey of the stellar contents associated with the star-forming Complex Sh2-252
Jessy Jose, A. K. Pandey, K. Ogura +8
We present the analyses of the stellar contents associated with the HII region Sh2-252 using UBVRI photometry, slit and slitless spectroscopy along with the NIR data from 2MASS for…
TIRCAM2: The TIFR Near Infrared Imaging Camera
M. B. Naik, D. K. Ojha, S. K. Ghosh +10
TIRCAM2 (TIFR Near Infrared Imaging Camera - II) is a closed cycle cooled imager that has been developed by the Infrared Astronomy Group at the Tata Institute of Fundamental Resear…
Multi-wavelength study of triggered star formation around mid-infrared bubble N14
L. K. Dewangan, D. K. Ojha
We present multi-wavelength analysis around mid-infrared bubble N14 to probe the signature of triggered star formation as well as the formation of new massive star(s) and/or cluste…
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…
Triggered star formation around mid-infrared bubbles in G8.14+0.23 H II region
L. K. Dewangan, D. K. Ojha, B. G. Anandarao +2
Mid-infrared (MIR) shells or bubbles around expanding H II regions have received much attention due to their ability to initiate a new generation of star formation. We present mult…
