Star-forming site RAFGL 5085: Is a perfect candidate of hub-filament system?
Dewangan, L. K.; Pandey, Rakesh; Sharma, Saurabh +4 more
To investigate the star-formation process, we present a multi-wavelength study of a massive star-forming site RAFGL 5085, which has been associated with the molecular outflow, HII region and near-infrared cluster. The continuum images at 12, 250, 350 and 500
Far infrared properties of OH megamaser host galaxies
Wang, Jin; Lv, Bu-Hui; Lin, Ru-Qiu +8 more
The hosts of OH megamaser (OHM) are luminous infrared galaxies (LIRGs), in fact 1/3 of them are ultra-luminous infrared galaxies (ULIRGs), which imply that OHM phenomena should be related to the infrared radiation field. In this paper, we investigate the far infrared (FIR) properties of OHM host galaxies, through detailed infrared data covering br…
Kronberger 55: A candidate for end-dominated collapse scenario
Pandey, Rakesh; Sharma, Saurabh; Dewangan, Lokesh +5 more
Using optical photometric observations from 1.3-m Devasthal Fast Optical Telescope and deep near-infrared (NIR) photometric observations from TANSPEC mounted on 3.6-m Devasthal Optical Telescope, along with the multi-wavelength archival data, we present our study of open cluster Kronberger 55 to understand the star-formation scenario in the region…
Role of magnetic fields in the fragmentation of the Taurus B213 filament into Sun-type star-forming cores
Jose, Jessy; Eswaraiah, Chakali; Jiao, Sihan +1 more
Fragmentation is a key step in the process of transforming clouds (and their substructures, such as filaments, clumps and cores) into protostars. The thermal gas pressure and gravitational collapse are believed to be the primary agents governing this process, referred as thermal Jeans fragmentation. However, the contributions of other factors (suc…
Investigating star-formation activity in Sh 2-61 H II region
Pandey, Rakesh; Sharma, Saurabh; Dewangan, Lokesh +4 more
Using multi-wavelength data sets, we studied the star-formation activity in H II region Sh 2-61 (hereafter S61). We identified a clustering in the region and estimated the membership using the Gaia proper motion data. The physical environment of S61 is inspected using infrared to radio wavelength images. We also determined the Lyman continuum flux…
