Understanding formation of young, distributed low-mass stars and clusters in the W4 cloud complex
Neelam Panwar, Manash R. Samal, A. K. Pandey +2
It is well known that most of the stars form in rich clusters. However, recent observations have shown that a significant number of stars also form in distributed mode, o…
Young cluster Berkeley 59 : Properties, evolution and star formation
Neelam Panwar, A. K. Pandey, Manash R. Samal +5
Berkeley 59 is a nearby (1 kpc) young cluster associated with the Sh2-171 H{\sc ii} region. We present deep optical observations of the central 2.52.5 pc ar…
How do stars gain their mass? A JCMT/SCUBA-2 Transient Survey of Protostars in Nearby Star Forming Regions
Gregory J. Herczeg, Doug Johnstone, Steve Mairs +55
Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accreti…
The low-mass population in the young cluster Stock 8: Stellar properties and Initial Mass Function
Jessy Jose, Gregory J. Herczeg, Manash R. Samal +2
The evolution of HII regions/supershells can trigger a new generation of stars/clusters at their peripheries, with environmental conditions that may affect the initial mass functio…
The young cluster NGC 2282 : a multi-wavelength perspective
