AGB winds in interacting binary stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We perform numerical simulations to investigate the stellar wind from interacting binary stars. Our aim is to find analytical formulae describing the outflow structure. In each binary system the more massive star is in the asymptotic giant branch (AGB) and its wind is driven by a combination of pulsations in the stellar surface ...

Detailed models of interacting short-period massive binary stars [PDF]
Astronomy & Astrophysics, 2021 Context. The majority of massive stars are part of binary systems. In about a quarter of these, the companions are so close that mass transfer occurs while they undergo core hydrogen burning, first on the thermal and then on the nuclear timescale. The nuclear timescale mass transfer leads to observational counterparts: the semi-detached so-called ...

Be Stars as Interacting Binaries [PDF]
Symposium - International Astronomical Union, 1982 At the last IAU Symposium on Be stars held in Bass River, MA in 1975, several of us (including P. Harmanec, M. Plavec, R.S. Polidan, and myself) suggested that Be stars are mass transfer binaries and represent the higher mass counterparts to the familiar Algol systems.

On ageing star clusters using red supergiants independent of the fraction of interacting binary stars [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 We use the Binary Population and Spectral Synthesis models to test the recent suggestion that red supergiants can provide an accurate age estimate of a coeval stellar population that is unaffected by interacting binary stars.

Ultraviolet Observations of Interacting Binary Be Stars [PDF]
Symposium - International Astronomical Union, 1982 Initial results from the analysis of a series of timed, high resolution IUE observations of HR 2142, ϕ Per, CX Dra, KX And, AU Mon, and TT Hya are presented. The data base for HR 2142 also includes Copernicus U1 and U2 observations. Variable absorption lines, indicative of mass flow in the system, are observed in all objects except ϕ Per.

Orbital evolution of potentially habitable planets of tidally interacting binary stars [PDF]
Astronomy & Astrophysics, 2020 We simulate the coupled stellar and tidal evolution of short-period binary stars (orbital period Porb ≲ 8 days) to investigate the orbital oscillations, instellation cycles, and orbital stability of circumbinary planets (CBPs).

Be Stars in Roche-Lobe Interacting Binaries [PDF]
International Astronomical Union Colloquium, 2000 AbstractDifferent types of massive interacting binaries with Be components are discussed. Due to mass exchange, Be stars in these systems have some peculiar characteristics. Often it is even difficult to find traces of the Be star and/or mass-losing star in the optical region of the spectrum. Using the value of the orbital period as a primary parameter,

Mass-transferring binary stars as progenitors of interacting hydrogen-free supernovae [PDF]
Astronomy & AstrophysicsStripped-envelope supernovae (SNe) are hydrogen-poor transients produced at the end of the life of massive stars that have previously lost most or all of their hydrogen-rich envelope.

IMAGES OF GRAVITATIONAL AND MAGNETIC PHENOMENA DERIVED FROM TWO-DIMENSIONAL BACK-PROJECTION DOPPLER TOMOGRAPHY OF INTERACTING BINARY STARS [PDF]
, 2014 We have used two-dimensional back-projection Doppler tomography as a tool to examine the influence of gravitational and magnetic phenomena in interacting binaries that undergo mass transfer from a magnetically active star onto a non-magnetic main ...
