Asteroseismology of Close Binary Stars [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractIn this review paper, we summarise the goals of asteroseismic studies of close binary stars. We first briefly recall the basic principles of asteroseismology, and highlight how the binarity of a star can be an asset, but also a complication, for the interpretation of the stellar oscillations.

Surveying Planetary Nebulae Central Stars for Close Binaries: Constraining Evolution of Central Stars Based on Binary Parameters

open access: yesGalaxies, 2018
The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

Asteroseismic effects in close binary stars [PDF]

open access: yes, 2013
Turbulent processes in the convective envelopes of the sun and stars have been shown to be a source of internal acoustic excitations. In single stars, acoustic waves having frequencies below a certain cutoff frequency propagate nearly adiabatically and ...

Close Binary Companions to APOGEE DR16 Stars: 20,000 Binary-star Systems Across the Color–Magnitude Diagram [PDF]

open access: yesAstrophysical Journal, 2020
Many problems in contemporary astrophysics—from understanding the formation of black holes to untangling the chemical evolution of galaxies—rely on knowledge about binary stars.

A 12.4-day periodicity in a close binary system after a supernova [PDF]

open access: yesNature, 2023
Neutron stars and stellar-mass black holes are the remnants of massive star explosions1. Most massive stars reside in close binary systems2, and the interplay between the companion star and the newly formed compact object has been theoretically explored3,

The Evolution of Massive Binary Stars [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2023
Massive stars play a major role in the evolution of their host galaxies and serve as important probes of the distant Universe. It has been established that the majority of massive stars reside in close binaries and interact with their companion stars ...

Photometric study of close binary stars in the M35, M67, and M71 Galactic clusters [PDF]

open access: yesContributions of the Astronomical Observatory Skalnaté Pleso, 2020
We obtained new multicolour photometry of close binary stars in the young open cluster M35, the solar-age open cluster M67, and the globular cluster M71. New observations have been carried out at the TUBITAK National Observatory (TUG) by using the 100cm (

Asteroseismology of Close Binary Stars: Tides and Mass Transfer

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The study of stellar oscillations allows us to infer the properties of stellar interiors. Meanwhile, fundamental parameters such as mass and radius can be obtained by studying stars in binary systems. The synergy between binarity and asteroseismology can

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 ...

NY Bootes: An Active Deep and Low-mass-ratio Contact Binary with a Cool Companion in a Hierarchical Triple System

open access: yesThe Astrophysical Journal, 2023
The first detailed photometric and spectroscopic study of G-type short-period binary NY Boo is presented. The radial velocity curve was obtained by the cross-correlation function (CCF) method based on LAMOST and SDSS spectra, which derived its mass ratio
