Massive star-formation in the hub-filament system of RCW 117
Arun Seshadri, S. Vig, S. K. Ghosh +1
We present a multiwavelength investigation of the hub-filament system RCW 117 (IRAS 17059-4132), which shows intricate filamentary features in the far-infrared, mapped using Hersch…
Gas Kinematics in the HII regions G351.69-1.15 and G351.63-1.25
V. S. Veena, S. Vig, A. Tej +2
We probe the structure and kinematics of two neighbouring H II regions identified as cometary and bipolar, using radio recombination lines (RRL). The H172α RRLs from these H II re…
Excitation mechanism of OI lines in Herbig Ae/Be stars
Blesson Mathew, P. Manoj, Mayank Narang +7
We have investigated the role of a few prominent excitation mechanisms viz. collisional excitation, recombination, continuum fluorescence and Lyman beta fluorescence on the OI line…
Investigating star-formation activity towards the southern HII region RCW 42
Vipin Kumar, S. Vig, V. S. Veena +4
The star-forming activity in the HII region RCW 42 is investigated using multiple wavebands, from near-infrared to radio wavelengths. Located at a distance of 5.8 kpc, this souther…
Star formation activity in the southern Galactic HII region G351.63-1.25
S. Vig, S. K. Ghosh, D. K. Ojha +2
The southern Galactic high mass star-forming region, G351.6-1.3, is a HII region-molecular cloud complex with a luminosity of 2.0 x 10^5 L_sun, located at a distance of 2.4 kpc. In…
New radio lobes at parsec scale from the East-West protostellar jet RAFGL2591
A. G. Cheriyan, S. Vig, Sreelekshmi Mohan
RAFGL2591 is a massive star-forming complex in the Cygnus-X region comprising of a cluster of embedded protostars and young stellar objects located at a distance of 3.33 kpc. We in…
