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

Born to Be Wide: The Distribution of Wide Binaries in the Field and Soft Binaries in Clusters
The Astrophysical Journal, 2023 Most stars, binaries, and higher-multiplicity systems are thought to form in stellar clusters and associations that later dissociate. Very wide binaries can be easily disrupted in clusters due to dynamical evaporation (soft binaries) and/or tidal ...

Tidally Excited Oscillations in Heartbeat Binary Stars: Pulsation Phases and Mode Identification [PDF]
Astrophysical Journal, 2019 Tidal forces in eccentric binary stars known as heartbeat stars excite detectable oscillations that shed light on the processes of tidal synchronization and circularization.

Binary Stars in Upper Scorpius [PDF]
Astronomical Journal, 2019 To address the statistics of binary stars in the 8 Myr old Upper Scorpius (USco) star formation region, we conducted a speckle interferometric survey of 614 association members more massive than 0.4 (spectral types earlier than M3V) based on the list of ...

The eccentric behaviour of windy binary stars [PDF]
Astronomy & Astrophysics, 2019 Carbon-enhanced metal-poor stars, CH stars, barium stars, and extrinsic S stars, among other classes of chemically peculiar stars, are thought to be the products of the interaction of low- and intermediate-mass binaries, which occurred when the most ...

Mind Your Ps and Qs: The Interrelation between Period (P) and Mass-ratio (Q) Distributions of Binary Stars [PDF]
, 2016 We compile observations of early-type binaries identified via spectroscopy, eclipses, long-baseline interferometry, adaptive optics, common proper motion, etc.

Binary stars as the key to understanding planetary nebulae [PDF]
Nature Astronomy, 2017 Planetary nebulae are traditionally considered to represent the final evolutionary stage of all intermediate-mass stars (∼0.7–8 M☉). Recent evidence seems to contradict this picture.

Asteroseismology of binary stars and a compilation of core overshoot and rotational frequency values of OB stars [PDF]
, 2013 After a brief introduction into the asteroseismic modelling of stars, we provide a compilation of the current seismic estimates of the core overshooting parameter and of the rotational frequency of single and binary massive stars. These important stellar

Classification of close binary stars using recurrence networks. [PDF]
Chaos, 2019 Close binary stars are binary stars where the component stars are close enough such that they can exchange mass and/or energy. They are subdivided into semidetached, overcontact, or ellipsoidal binary stars.
