Be binary stars with hot, compact companions [PDF]
, 2003 In this study the importance of close binary evolution for Be star formation was investigated. The Be star 59 Cygni was confirmed to be an evolved binary with a sdO companion. The companion was confirmed by a weak helium II absorption. Orbital elements and stellar masses were determined.

Evolution of binary stars in multiple-population globular clusters – II. Compact binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We present the results of a survey of N-body simulations aimed at exploring the evolution of compact binaries in multiple-population globular clusters.We show that as a consequence of the initial differences in the structural properties of the first-generation (FG) and the second-generation (SG) populations and the effects of dynamical processes on ...

Orbital parameters estimation for compact binary stars [PDF]
Most stars in the Galaxy are found in multiple systems of two or more stars orbiting together. Two stars orbiting around their centre of mass are called binary stars. In close binary stars, the evolution of one star affects its companion and evolutionary expansion of one star allows for mass exchange between the components.

Mass transfer and evolution of compact binary stars
, 2022 We present a study of key aspects of the evolution of binary stars with emphasis on binaries consisting of two white dwarf stars. The evolution of such systems is driven by the loss of angular momentum by gravitational wave radiation.

LTD064402+245919, Compact Binary or Subgiant with Red Star Eclipsing Binary?
Research Notes of the AAS, 2022 Abstract Recently, a single-line spectroscopic binary, LTD064402+245919, has been discovered by Yang et al. Using data from LAMOST and ZTF, the unseen companion is estimated to have a mass of 1–3 M ⊙, orbiting a subgiant with orbital period of 14.50 days, making it a good compact binary candidate without X-ray emission.

European Physical Journal C: Particles and FieldsThe present study is based on $$f(\mathscr {T})$$ f ( T ) gravity, where we impose possible observational constraints on the model parameters to obtain physically plausible features of compact stars, specifically neutron stars. To do so, as a first step,

Population Properties of Neutron Stars in the Coalescing Compact Binaries
The Astrophysical Journal, 2021 Abstract We perform a hierarchical Bayesian inference to investigate the population properties of the coalescing compact binaries involving at least one neutron star (NS). With the current gravitational-wave (GW) observation data, we can rule out none of the double Gaussian, single Gaussian, and uniform NS mass distribution models ...

Great Impostors: Extremely Compact, Merging Binary Neutron Stars in the Mass Gap Posing as Binary Black Holes [PDF]
, 2023 Can one distinguish a binary black hole undergoing a merger from a binary neutron star if the individual compact companions have masses that fall inside the so-called mass gap of 3-5 M⊙?

Gravitoastronomy with neutron stars [PDF]
, 2004 Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.
