Studying VLOCV twin compact stars with binary mergers [PDF]
Physical Review D, 2021 GW170817 has provided valuable constraints on the equations of state of merging binary neutron stars, which can be considered as the most probable candidate for the source of gravitational waves. On the other hand, these natural laboratories of extreme temperature and density may lead to the estimation of some exotic matter like {deconfined quark ...

The Evolution of Massive Binary Stars [PDF]
Annual 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 ...

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.

Binary stars in the new millennium [PDF]
Progress in Particle and Nuclear Physics, 2023 Binary stars are as common as single stars. Binary stars are of immense importance to astrophysicists because that they allow us to determine the masses of the stars independent of their distances. They are the cornerstone of the understanding of stellar

The ELM Survey South. II. Two Dozen New Low-mass White Dwarf Binaries
The Astrophysical Journal, 2023 We present the results from our ongoing spectroscopic survey targeting low-mass white dwarf binaries, focusing on the southern sky. We used a Gaia DR2- and eDR3-based selection and identified 28 new binaries, including 19 new extremely low-mass (ELM ...

The evolution of massive binary systems [PDF]
Serbian Astronomical Journal, 2020 The evolution of massive stars in close binary systems is significantly different from single star evolution due to a series of interactions between the two stellar components.

White Dwarfs Revealed in Gaia’s Candidate Compact Object Binaries
The Astrophysical Journal, 2023 Discovery and characterization of black holes (BHs), neutron stars (NSs), and white dwarfs (WDs) with detached luminous companions (LCs) in wide orbits are exciting because they are important test beds for dark remnant (DR) formation physics as well as ...

Exploring compact binary populations with the Einstein Telescope [PDF]
Astronomy & Astrophysics, 2021 The Einstein Telescope (ET), a wide-band, future third generation gravitational wave detector, is expected to have detection rates of $\sim 10^5 - 10^6$ binary black hole (BBH) detections and $\sim 7 \times 10^4$ binary neutron star (BNS) detections in ...

Exploring compact binary merger host galaxies and environments with zELDA [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Compact binaries such as double neutron stars or a neutron star paired with a black-hole, are strong sources of gravitational waves during coalescence and also the likely progenitors of various electromagnetic phenomena, notably short-duration gamma ...
