Spectroscopy of the massive interacting binary UU Cassiopeiae [PDF]

open access: yesAstronomy & Astrophysics, 2022
Context. The eclipsing close binary UU Cas is an interacting massive double-periodic system with a gainer star partly hidden in an accretion disk. Aims.

Quasiequilibrium configurations of binary systems of dark matter admixed neutron stars [PDF]

open access: yesPhysical Review D, 2023
Using an adapted version of the SGRID code, we construct for the first time consistent quasi-equilibrium configurations for a binary system consisting of two neutron stars in which each is admixed with dark matter.

Interacting supernovae from wide massive binary systems [PDF]

open access: yesAstronomy & Astrophysics, 2023
The features in the light curves and spectra of many I and II supernovae (SNe) can be understood by assuming an interaction of the SN ejecta with circumstellar matter (CSM) surrounding the progenitor star.

The Formation of Black Holes in Non-interacting, Isolated Binaries. Gaia Black Holes as Calibrators of Stellar Winds From Massive Stars

open access: greenAstronomy & Astrophysics
The black holes discovered using Gaia especially Gaia BH1 and BH2, have low-mass companions of solar-like metallicity in wide orbits. For standard formation channels of isolated binary evolution that include interactions, this extreme mass ratio is ...

Fast Radio Bursts from Interacting Binary Neutron Star Systems [PDF]

open access: yesAstrophysical Journal, 2020
Recent observations of repeating fast radio bursts (FRBs) suggest that some FRBs reside in an environment consistent with that of binary neutron star (BNS) mergers. The bursting rate for repeaters could be very high and the emission site is likely from a

New insights on the massive interacting binary UU Cassiopeiae [PDF]

open access: yesAstronomy & Astrophysics, 2020
We present the results of our study of the close binary UU Cassiopeiae based on previously published multiwavelength photometric and spectroscopic data.

Accretion and Intercycle Variations in the PMS Interacting Binary AK Sco [PDF]

open access: yesAstrophysical Journal, 2020
There are only a handful of known short-period pre-main-sequence spectroscopic binaries with significant accretion rates (Class II sources). AK Sco stands out in this list because the system is composed of two equal mass F5 stars in a highly eccentric ...

Adiabatic Mass Loss in Binary Stars. III. From the Base of the Red Giant Branch to the Tip of the Asymptotic Giant Branch [PDF]

open access: yesAstrophysical Journal, 2020
The distinguishing feature of the evolution of close binary stars is the role played by the mass exchange between the component stars. Whether or not the mass transfer is dynamically stable is one of the essential questions in binary evolution.

How unique is Plaskett's star? A search for organized magnetic fields in short period, interacting or post-interaction massive binary systems [PDF]

open access: yes, 2017
Amongst O-type stars with detected magnetic fields, the fast rotator in the close binary called Plaskett's star shows a variety of unusual properties.

The impact of binary-star yields on the spectra of galaxies [PDF]

open access: yes, 2009
One of the complexities in modelling integrated spectra of stellar populations is the effect of interacting binary stars besides Type Ia supernovae (SNeIa).
