Numerical Simulations of Magnetized Winds of Solar-Like Stars
A. A. Vidotto, M. Opher, V. Jatenco-Pereira +1
We investigate magnetized solar-like stellar winds by means of self-consistent three-dimensional (3D) magnetohydrodynamics (MHD) numerical simulations. We analyze winds with differ…
Modelling spectral line profiles of wind-wind shock emissions from massive binary systems
D. Falceta-Goncalves, Z. Abraham, V. Jatenco-Pereira
One of the most intriguing spectral features of WR binary stars is the presence of time-dependent line profiles. Long term observations of several systems revealed the periodicity…
A self-consistent determination of the temperature profile and the magnetic field geometry in winds of late-type stars
A. A. Vidotto, D. Falceta-Goncalves, V. Jatenco-Pereira
Cool giant and supergiant stars generally present low velocity winds with high mass loss rates. Several models have been proposed to explain the acceleration process of these winds…
On the magnetic structure and wind parameter profiles of Alfven wave driven winds in late-type supergiant stars
D. Falceta-Goncalves, A. A. Vidotto, V. Jatenco-Pereira
Cool stars at giant and supergiant evolutionary phases present low velocity and high density winds, responsible for the observed high mass-loss rates. Although presenting high lumi…
The Effects of Alfven Waves and Radiation Pressure in Dusty Winds of Late-Type Stars. II. Dust-Cyclotron Damping
A. A. Vidotto, V. Jatenco-Pereira
There are in the literature several theories to explain the mass loss in stellar winds. In particular, for late-type stars, some authors have proposed a wind model driven by an out…
Wind-wind collision in the Carinae binary system II: Constrains to the binary orbital parameters from radio emission near periastron passage
Z. Abraham, D. Falceta-Goncalves, T. P. Dominici +2
In this paper we use the 7 mm and 1.3 mm light curves obtained during the 2003.5 low excitation phase of the eta Carinae system to constrain the possible parameters of the binary o…
