Eclipsing binaries in extrasolar planet transit surveys: the case of SuperWASP
Extrasolar planet transit surveys will also detect eclipsing binaries. Using a comprehensive binary population synthesis scheme, we investigate the statistical properties of a sample of eclipsing binaries that is detectable by an idealised extrasolar planet transit survey with specifications broadly similar to those of the SuperWASP (Wide Angle Search for Planets) project. In this idealised sur...
متن کاملAn Algorithm to Detect Blends with Eclipsing Binaries in Planet Transit Searches
We present an algorithm that can detect blends of bright stars with fainter, un-associated eclipsing binaries. Such systems contaminate searches for transiting planets, in particular in crowded fields where blends are common. Spectroscopic follow-up observations on large aperture telescopes have been used to reject these blends, but the results are not always conclusive. Our approach exploits t...
متن کاملThe Final Fate of Coalescing Compact Binaries: from Black Hole to Planet Formation
Coalescing compact binaries are thought to be involved in a wide variety of astrophysical phenomena. In particular, they are important sources of gravitational radiation for both ground-based and space-based laser-interferometer detectors, and they may be sources of supernova explosions or gamma-ray bursts. Mergers of two white dwarfs may produce neutron stars with peculiar properties, includin...
متن کامل2 00 7 Medium – separation binaries do not affect the first steps of planet formation
The first steps of planet formation are marked by the growth and crystallization of sub–micrometer–sized dust grains accompanied by dust settling toward the disk midplane. In this paper we explore whether the first steps of planet formation are affected by the presence of medium–separation stellar companions. We selected two large samples of disks around single and binary T Tauri stars in Tauru...
متن کاملDynamical Outcomes of Planet–planet Scattering
Observations in the past decade have revealed extrasolar planets with a wide range of semi-major axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations. While the protoplanets are embedded in a protoplanetary nebula, dissipation prevents eccentricity growth...
