Weak secondary cyclotron line in eclipsing High Mass X-ray Binary Cen X-3
Pravat Dangal, Ranjeev Misra, Nand Kumar Chakradhari +1
We report the time resolved spectroscopy result from two observations of Cen X-3, over one binary orbit with ASTROSAT and two binary orbit with NuSTAR. NuSTAR covered two intensity…
Observational properties of a Type Ib Supernova MASTER OT J120451.50+265946.6 in NGC 4080
Mridweeka Singh, Kuntal Misra, D. K. Sahu +12
MASTER OT J120451.50+265946.6 (M12045), discovered by the MASTER Global Robotic Net, is a Type Ib supernova (SN) that exploded in NGC 4080. We present the {\it BVRI} photometric an…
Highly reddened type Ia supernova SN 2004ab: another case of anomalous extinction
N. K. Chakradhari, D. K. Sahu, G. C. Anupama +1
We present optical photometric and spectroscopic results of supernova SN 2004ab, a highly reddened normal type Ia supernova. The total reddening is estimated as = 1.70 $\p…
Exploring the optical behaviour of a type Iax supernova SN 2014dt
Mridweeka Singh, Kuntal Misra, D. K. Sahu +9
We present optical photometric (upto 410 days since ) and spectroscopic (upto 157 days since ) observations of a Type Iax supernova (SN) 2014dt lo…
The hot Gamma-Doradus and Maia stars
L. A. Balona, C. A. Engelbrecht, Yogesh C. Joshi +8
The hot ~Doradus stars have multiple low frequencies characteristic of ~Dor or SPB variables, but are located between the red edge of the SPB and the blue edge of the ~Dor…
The Nainital-Cape Survey-IV
Santosh Joshi, P. Martinez, Sowgata Chowdhury +6
The Nainital-Cape survey is a dedicated ongoing survey programme to search for and study pulsational variability in chemically peculiar (CP) stars to understand their internal stru…
