Further evidence for intra-night optical variability of radio-quiet quasars
A. Goyal, Gopal-Krishna, Ram Sagar +2
Although well established for BL Lac objects and radio-loud quasars, the occurrence of intra-night optical variability (INOV) in radio-quiet quasars is still debated, primarily sin…
Broad Band Optical Polarimetric Study of IC 1805
Biman J. Medhi, Maheswar G., Brijesh K. +3
We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled…
UBVRI CCD photometry of the OB associations Bochum 1 and Bochum 6
R. K. S. Yadav, Ram Sagar
We report the first deep CCD photometry of 2460 stars in the field of two poorly studied OB associations Bochum 1 and Bochum 6. We selected 15 and 14 probable members in Bo…
SN 2002ap, the hypernova of class Ic
S. B. Pandey, D. K. Sahu, G. C. Anupama +2
The supernova SN 2002ap was discovered in the outer regions of the nearby spiral M74 on January 29.4 UT. Early photometric and spectroscopic observations indicate the supernova bel…
On mass and velocity distributions in members of star clusters : An analytical approach
S. Chatterjee, Brijesh Kumar, Ram Sagar
Dynamical evolution of stellar mass distribution in star clusters is analysed by considering simultaneously the effects of dynamical friction, stochastic heating and the gravitatio…
Optical observations of the bright long duration peculiar GRB 021004 afterglow
S. B. Pandey, D. K. Sahu, L. Resmi +9
The CCD magnitudes in Johnson and Cousins and photometric passbands are determined for the bright long duration GRB 021004 afterglow from 2002 October 4 to 16 startin…
