The dynamical environment of the high-mass star-forming region G28.2880.364
Jyotirmoy Dey, Devendra K. Ojha, Jagadheep D. Pandian
Massive stars form within deeply embedded dust cores, and the development of hypercompact and ultracompact H II regions characterizes their early evolution. Identifying and analyzi…
Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi
Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14
EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…
Star-forming sites IC 446 and IC 447: an outcome of end-dominated collapse of Monoceros R1 filament
N. K. Bhadari, L. K. Dewangan, L. E. Pirogov +1
We present an analysis of multi-wavelength observations of Monoceros R1 (Mon R1) complex (at d ~760 pc). An elongated filament (length ~14 pc, mass ~1465 Msun) is investigated in t…
The molecular cloud S242: physical environment and star formation activities
L. K. Dewangan, T. Baug, D. K. Ojha +3
We present a multi-wavelength study to probe the star formation (SF) processes on a larger scale (~1.05 deg x 0.56 deg) around the S242 site. The S242 molecular cloud is depicted i…
Massive young stellar object W42-MME: The discovery of an infrared jet using VLT/NACO near-infrared images
L. K. Dewangan, Y. D. Mayya, A. Luna +1
We report on the discovery of an infrared jet from a deeply embedded infrared counterpart of 6.7 GHz methanol maser emission (MME) in W42 (i.e. W42-MME). We also investigate that W…
Deep J-band imaging of high redshift QSO candidates with the Himalayan Chandra Telescope
Tomotsugu Goto
High redshift QSOs (redshift5.7) are highly important objects. If such QSOs may be found, their spectra will reveal the onset of reionization of the intergalactic medium (Gunn-P…
