Absolute dimensions of eclipsing binaries***
Context. Double-lined, detached eclipsing binaries are our main source for accurate stellar masses and radii. This paper is the first in a series with focus on the upper half of the main-sequence band and tests of 1–2 M evolutionary models. Aims. We aim to determine absolute dimensions and abundances for the detached eclipsing binary V1130 Tau, and to perform a detailed comparison with results ...
متن کاملEclipsing binaries in ASAS catalog
ASAS is a long term project to monitor bright variable stars over the whole sky. It has discovered 50,122 variables brighter than V < 14 mag south of declination +28◦, and among them 11,099 eclipsing binaries. We present a preliminary analysis of 5,384 contact, 2,957 semi-detached, and 2,758 detached systems. The statistics of the distribution provides a qualitative confirmation of decades old ...
متن کاملEclipsing Binaries in Open Clusters
Detached eclipsing binaries are very useful objects for calibrating theoretical stellar models and checking their predictions. Detached eclipsing binaries in open clusters are particularly important because of the additional constraints on their age and chemical composition from their membership of the cluster. I compile a list containing absolute parameters of wellstudied eclipsing binaries in...
متن کاملPrecovery of Eclipsing Binaries: Identifying Eclipse Timing Variation among Kepler Eclipsing Binaries in KELT
The Asakura-Oosawa (AO) model describes the effective attractive interaction induced when two large colloidal bodies are immersed in a solvent consisting of smaller macromolecules. The effective interaction is induced due to an unbalanced osmotic pressure arising from the depletion of the macromolecules in the region between the two bodies. We model amelogenin, a hydrophobic protein and with a ...
متن کاملGAIA survey of galactic eclipsing binaries
General importance and capabilities of observations of eclipsing binaries by the forthcoming ESA mission GAIA are discussed. Availability of spectroscopic observations and a large number of photometric bands on board will make it possible to reliably determine physical parameters for ∼ 10 binary stars. It is stressed that current methods of object by object analysis will have to be modified and...
