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 qWR star HD 45166 - II. Fundamental stellar parameters and evidence of a latitude-dependent wind
(EDP SCIENCES S A, 2008)
Context. The enigmatic object HD 45166 is a qWR star in a binary system with an orbital period of 1.596 day, and presents a rich emission-line spectrum in addition to absorption lines from the companion star (B7 V). As the ...
Dust entrainment in photoevaporative winds: densities and imaging
(EDP Sciences, 2022)
Context. X-ray- and extreme-ultraviolet- (together: XEUV-) driven photoevaporative winds acting on protoplanetary disks around
young T-Tauri stars may crucially impact disk evolution, affecting both gas and dust ...
Limb-darkened radiation-driven winds from massive stars
(IOP Publishing, 2012-10)
We calculated the influence of the limb-darkened finite-disk correction factor in the theory of radiation-driven winds from massive stars. We solved the one-dimensional m-CAK hydrodynamical equation of rotating radiation-driven ...
