Wolf-Rayet optically thick winds with Alfven waves
(ELSEVIER SCI LTD, 2010)
The Wolf-Rayet (WR) stars are hot luminous objects which are suffering an extreme mass loss via a continuous stellar wind. The high values of mass loss rates and high terminal velocities of the WR stellar winds constitute ...
The mass-loss before the end : two luminous blue variables with a collimated stellar wind
(Cambridge University Press, 2016-11)
We gathered a multiwavelength dataset of two well-known LBVs. We found a com plex mass-loss, with evidence of variability, such as has been seen previously. In addition, our
data reveal signatures of collimated stellar ...
Metallicity effects on the modified wind momentum of CSPN
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2008)
Recent investigations on the central stars of planetary nebulae (CSPN) indicate that the masses based on model atmospheres can be much larger than the masses derived from theoretical mass-luminosity relations. Also, the ...
Wind properties of variable B supergiants. Evidence of pulsations connected with mass-loss episodes
(EDP Sciences, 2018-06)
Context. Variable B supergiants (BSGs) constitute a heterogeneous group of stars with complex photometric and spectroscopic behaviours. They exhibit mass-loss variations and experience different types of oscillation modes, ...
