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 ...
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 ...
THREE-DIMENSIONAL NUMERICAL SIMULATIONS OF MAGNETIZED WINDS OF SOLAR-LIKE STARS
(IOP PUBLISHING LTD, 2009)
By means of self-consistent three-dimensional magnetohydrodynamics (MHD) numerical simulations, we analyze magnetized solar-like stellar winds and their dependence on the plasma-beta parameter (the ratio between thermal ...
A cyclic bipolar wind in the interacting binary V 393 Scorpii
(WILEY-BLACKWELLHOBOKEN, 2012-11)
V393 Scorpii is a double periodic variable characterized by a relatively stable non-orbital photometric cycle of 253 d. Mennickent et al. argue for the presence of a massive optically thick disc around the more massive ...
SIMULATIONS OF WINDS OF WEAK-LINED T TAURI STARS: THE MAGNETIC FIELD GEOMETRY AND THE INFLUENCE OF THE WIND ON GIANT PLANET MIGRATION
(IOP PUBLISHING LTD, 2009)
By means of numerical simulations, we investigate magnetized stellar winds of pre-main-sequence stars. In particular, we analyze under which circumstances these stars will present elongated magnetic features (e.g., helmet ...
Colliding-wind binary systems: diffusive shock acceleration and non-thermal emission
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a model for the non-thermal emission from a colliding-wind binary. Relativistic protons and electrons are assumed to be accelerated through diffusive shock acceleration (DSA) at the global shocks bounding the ...
