2D unified atmosphere and wind simulations of O-type stars
D. Debnath, J. O. Sundqvist, N. Moens +3
Massive and luminous O-star atmospheres with winds have been studied primarily using one-dimensional (1D), spherically symmetric, and stationary models. However, observations and t…
Towards a unified view of inhomogeneous stellar winds in isolated supergiant stars and supergiant high mass X-ray binaries
Silvia Martínez-Núñez, Peter Kretschmar, Enrico Bozzo +13
Massive stars, at least 10 times more massive than the Sun, have two key properties that make them the main drivers of evolution of star clusters, galaxies, and the Universe…
A JVLA survey of the high frequency radio emission of the massive magnetic B- and O-type stars
Sushma Kurapati, Poonam Chandra, Gregg Wade +10
We conducted a survey of seven magnetic O and eleven B-type stars with masses above using the Very Large Array in the 1cm, 3cm and 13cm bands. The survey resulted in a…
An `Analytic Dynamical Magnetosphere' formalism for X-ray and optical emission from slowly rotating magnetic massive stars
Stanley P. Owocki, Asif ud-Doula, Jon O. Sundqvist +3
Slowly rotating magnetic massive stars develop "dynamical magnetospheres" (DM's), characterized by trapping of stellar wind outflow in closed magnetic loops, shock heating from col…
Physics of mass loss in massive stars
J. Puls, J. O. Sundqvist, N. Markova
We review potential mass-loss mechanisms in the various evolutionary stages of massive stars, from the well-known line-driven winds of O-stars and BA-supergiants to the less-unders…
Measuring the shock-heating rate in the winds of O stars using X-ray line spectra
David H. Cohen, Zequn Li, Kenneth G. Gayley +4
We present a new method for using measured X-ray emission line fluxes from O stars to determine the shock-heating rate due to instabilities in their radiation-driven winds. The hig…
