Investigation of variability of iron emission lines in Centaurus X-3

Sachindra Naik, Biswajit Paul

We present the results obtained from a study of the variability of iron emission lines in the high mass X-ray binary pulsar Cen X-3 during the eclipse, eclipse-egress and out-of-ec…

The expanding dusty bipolar nebula around the nova V1280 Sco

Olivier Chesneau, E. Lagadec, M. Otulakowska-Hypka +15

V1280 Sco is one of the slowest dust-forming nova ever historically observed. We performed multi-epoch high-spatial resolution observations of the circumstellar dusty environment o…

A study of the role of Lyman β fluorescence on OI line strengths in Be stars

Blesson Mathew, Dipankar P. K. Banerjee, Annapurni Subramaniam +1

The possibility of the Lyβ fluorescence mechanism being operational in classical Be stars and thereby contributing to the strength of the OI 8446 Å line has been recognized for lon…
