Binaries as Astrophysical Laboratories: Open Questions
Binary systems have long been recognized as the source of powerful astrophysical diagnostics. Among the many applications of binary stars, they have been used as probes of stellar structure and evolution (both of single and binary stars) in a broad range of masses, evolutionary stages, and chemical compositions, and as indicators of distance and time. With the numerous ongoing photometric surve...
متن کامل**full Title** Asp Conference Series, Vol. **volume**, **year of Publication** **names of Editors** Binaries as Astrophysical Laboratories: an Overview
The study of binary stars is worth to undertake not only to learn more about the properties of binaries as such, but also because binaries are multi-purpose astrophysical tools. This paper reviews some of the ways this effective “tool” can be used, focusing on fundamental parameter determination, tests of theoretical models, and the recent contribution of binary stars to establish the distance ...
متن کامل2 00 6 Pulsars as Astrophysical Laboratories for Nuclear and Particle Physics
A forefront area of research concerns the exploration of the properties of hadronic matter under extreme conditions of temperature and density, and the determination of the equation of state–the relation between pressure, temperature and density–of such matter. Experimentally, relativistic heavy-ion collision experiments enable physicists to cast a brief glance at hot and ultra-dense matter for...
متن کاملSpin and quadrupole contributions to the motion of astrophysical binaries
Compact objects in general relativity approximately move along geodesics of spacetime. It is shown that the corrections to geodesic motion due to spin (dipole), quadrupole, and higher multipoles can be modeled by an extension of the point mass action. The quadrupole contributions are discussed in detail for astrophysical objects like neutron stars or black holes. Implications for binaries are a...
متن کاملAstrophysical significance of detection of coalescing binaries with gravitational waves
We use the StarTrack stellar population synthesis code to analyze properties of double compact object binaries as sources of gravitational waves. Since the distribution of lifetimes of these objects extends up to the Hubble time we conclude that a proper calculation of the expected rate must include a full cosmological model. We present such model, calculate the expected coalescence rates, and ...
