Cyclic changes in the interacting binary RXCassiopeiae
Astronomy & Astrophysics, 2022 We analyzed 109 years of published photometry and times of minima of the eclipsing interacting binary RXCas. The inclusion of 171 previously unnoticed minima confirms the tendency of an increase in the orbital period at a rate of 1.84 seconds per cycle ...

Stellar Properties of Observed Stars Stripped in Binaries in the Magellanic Clouds
The Astrophysical Journal, 2023 Massive stars (∼8–25 M _⊙ ) stripped of their hydrogen-rich envelopes via binary interaction are thought to be the main progenitors for merging neutron stars and stripped-envelope supernovae.

Star-disc interactions and binary star formation [PDF]
Monthly Notices of the Royal Astronomical Society, 1991 The possibility of a large, massive protostellar accretion disc playing a role in the formation of binary stars by enabling the capture of a passing star within a dense star-forming region is analyzed. It is found that capture rates are too low to play a major role in all known star-forming environments, particularly when the probability of prior disc ...

Young Binary Star/Disk Interactions [PDF]
International Astronomical Union Colloquium, 1996 AbstractYoung binary star systems have associated gaseous disks that affect their evolution. Strong tidal forces of a binary give rise to gaps that separate circumstellar (CS) disks from the circumbinary (CB) disk. We discuss two important processes that involve binary/disk interactions.

New insights on the massive interacting binary UU Cassiopeiae [PDF]
Astronomy & Astrophysics, 2020 We present the results of our study of the close binary UU Cassiopeiae based on previously published multiwavelength photometric and spectroscopic data.

Binary Interaction Dominates the Evolution of Massive Stars [PDF]
Science, 2012 Star Partners Stars more massive than eight times the mass of the Sun are rare and short-lived, yet they are fundamentally important because they produce all the heavy elements in the universe, such as iron, silicon, and calcium. Sana et al. (p. 444

Photometric Observations of Eccentric Accretion in Algol-type Binary Stars [PDF]
Journal of Astronomy and Space Sciences, 2012 Some Algol-type interacting binary stars exhibit strange photometric variations that can be phase-dependent and/or secular. This paper discusses the possibility of explaining these observed variations as resulting from an accretion structure eclipsing ...

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