Exploring pulsational instabilities in the O-type supergiant HD 152249
Subharthi Dasgupta, Abhay Pratap Yadav, Sugyan Parida +1
Variability in O-type supergiants is a well known phenomena although their origin is not fully understood. In very massive, luminous stars, strange mode pulsations have been sugges…

Instabilities in models of supergiants MWC 137 and MWC 314
Sugyan Parida, Abhay Pratap Yadav, Santosh Joshi
In several B-type supergiants photometric and spectroscopic variabilities together with episodes of enhanced mass-loss have been observed. Here we present the preliminary results o…

On the stability and pulsation in models of B[e] star MWC 137
Sugyan Parida, Abhay Pratap Yadav, Michaela Kraus +3
B[e] type stars are characterised by strong emission lines, photometric spectroscopic variabilities and unsteady mass-loss rates. MWC 137 is a galactic B[e] type star situated…
