Elliptical polarimetry of the interacting binary stars V367 Cygni

open access: yesThe Astrophysical Journal, 1993
Elliptical polarization measures of the interacting binary star V367 Cyg were obtained. A two-component model for the circumbinary environment has been constructed.

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.

V1507 CYGNI (HD187399): A Highly Evolved, Enigmatic Interacting Binary System with an Eccentric Orbit

open access: yesThe Astronomical Journal, 2023
The properties of the interacting, eccentric orbit binary V1507 Cyg (HD187399) are examined with spectra that cover wavelengths from 0.63–0.68 μ m. The spectrum of the brightest star is similar to that of the B8 I star β Ori, although with absorption ...

The Environments around W Serpentis Systems: Independent Limits on System Masses and Extended Envelopes

open access: yesThe Astronomical Journal, 2023
Information extracted from the Gaia Data Release 3 is used to examine the stellar contents within projected separations of 10 pc from eight close binary systems that are either classical W Serpentis systems or related objects.

POSYDON: A General-purpose Population Synthesis Code with Detailed Binary-evolution Simulations

open access: yesThe Astrophysical Journal Supplement Series, 2023
Most massive stars are members of a binary or a higher-order stellar system, where the presence of a binary companion can decisively alter their evolution via binary interactions. Interacting binaries are also important astrophysical laboratories for the

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

The Impact of Angular Momentum Loss on the Outcomes of Binary Mass Transfer

open access: yesThe Astrophysical Journal, 2023
We use the rapid binary population synthesis code COMPAS to investigate commonly used prescriptions for the determination of mass transfer stability in close binaries and the orbital separations after stable mass transfer.
