Binary Star Database (BDB): New Developments and Applications
Data, 2018 Binary star DataBase (BDB) is the database of binary/multiple systems of various observational types. BDB contains data on physical and positional parameters of 260,000 components of 120,000 stellar systems of multiplicity 2 to more than 20, taken from a

Thermal Effects in Binary Neutron Star Mergers
The Astrophysical Journal Letters, 2023 We study the impact of finite-temperature effects in numerical-relativity simulations of binary neutron star mergers with microphysical equations of state and neutrino transport in which we vary the effective nucleon masses in a controlled way.

Proceedings of the International Astronomical Union, 2006 Only a handful of binary central stars of planetary nebulae (PNe) are known today, due to the difficulty of detecting their companions. Preliminary results from radial velocity surveys, however, seem to indicate that binarity plays a fundamental,rather than marginal role in the evolution of PNe and that the close binary fraction might be much larger ...

Bumpy Superluminous Supernovae Powered by a Magnetar–Star Binary Engine
The Astrophysical Journal LettersWolf–Rayet stars in close binary systems can be tidally spun up by their companions, potentially leaving behind fast-spinning, highly magnetized neutron stars, known as “magnetars,” after core collapse.

The Case for Edge-on Binaries: An Avenue Toward Comparative Exoplanet Demographics
The Astrophysical Journal LettersMost Sun-like and higher-mass stars reside in systems that include one or more gravitationally bound stellar companions. These systems offer an important probe of planet formation in the most common stellar systems, while also providing key insights into

Fundamental Parameters of a Binary System Consisting of a Red Dwarf and a Compact Star
The Astronomical JournalTIC 157365951 has been classified as a δ Scuti type by the International Variable Star Index. Through the spectra from Large Sky Area Multi-Object Fiber Spectroscopic Telescope and its light curve, we further discovered that it is a binary system.

Finding binaries from phase modulation of pulsating stars with Kepler
EPJ Web of Conferences, 2017 Binary orbital motion causes a periodic variation in the path length travelled by light emitted from a star towards us. Hence, if the star is pulsating, the observed phase of the pulsation varies over the orbit.

The Lifetime of Binary Stars [PDF]
International Astronomical Union Colloquium, 1977 AbstractThe concept of the “lifetime” of a population of binaries is applicable only to those of low binding energy, i.e. wide pairs. Of several possible methods of estimating a lifetime, that based on the average change in binding energy due to non-disruptive encounters appears to be the best.
