2.5-dimensional solution of the advective accretion disk: A self-similar approach
Shubhrangshu Ghosh, Banibrata Mukhopadhyay
We provide a 2.5-dimensional solution to a complete set of viscous hydrodynamical equations describing accretion-induced outflow and then plausible jet around black holes/compact o…
Kinematics of the Young Stellar Objects associated with the Cometary Globules in the Gum Nebula
Rumpa Choudhury, H. C. Bhatt
An analysis of proper motion measurements of the Young Stellar Objects (YSOs) associated with the Cometary Globules (CGs) in the Gum Nebula is presented. While earlier studies base…
Obscured and powerful AGN and starburst activities at z~3.5
M. Polletta, A. Omont, S. Berta +9
We report the discovery of two sources at z=3.867 and z=3.427 that exhibit powerful starburst and AGN activities. They benefit from data from radio to X rays from the CFHTLS-D1/SWI…
Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star
A. F. Lanza, I. Pagano, G. Leto +18
The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered as a good proxy for the Sun a…
Optical photometry and spectroscopy of the type Ibn supernova SN 2006jc until the onset of dust formation
G. C. Anupama, D. K. Sahu, U. K. Gurugubelli +4
We present optical UBVRI photometric and spectroscopic data of the type Ibn supernova SN 2006jc, until the onset of the dust forming phase. The optical spectrum shows a blue contin…
Optical and near-IR photometric study of the open cluster NGC 637 and NGC 957
R. K. S. Yadav, Brijesh Kumar, A. Subramaniam +2
We present UBVRI CCD photometry in the region of the open clusters NGC 637 and NGC 957. The radii are found to be 4.2 arcmin and 4.3 arcmin. Their reddenings E(B-V) are 0.64+/-0.05…
