ON THE NATURE OF THE PROTOTYPE LUMINOUS BLUE VARIABLE AG CARINAE. II. WITNESSING A MASSIVE STAR EVOLVING CLOSE TO THE EDDINGTON AND BISTABILITY LIMITS
(IOP PUBLISHING LTD, 2011)
We show that the significantly different effective temperatures (T(eff)) achieved by the luminous blue variable AG Carinae during the consecutive visual minima of 1985-1990 (T(eff) similar or equal to 22,800 K) and 2000-2001 ...
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 ...
Equatorial outflows driven by jets in Population III microquasars
(Springer, 2021-01)
Binary systems of Population III can evolve to microquasars when one of the stars collapses into a black hole. When the compact object accretes matter at a rate greater than the Eddington rate, powerful jets and winds ...
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 ...
