Physical parameters and multiplicity of five southern close eclipsing binaries
Aims. Detect tertiary components of close binaries from spectroscopy and light curve modelling; investigate light-travel time effect and the possibility of magnetic activity cycles; measure mass-ratios for unstudied systems and derive absolute parameters. Methods. We carried out new photometric and spectroscopic observations of five bright (〈V〉 < 10.5 mag) close eclipsing binaries, predominantl...
متن کاملCoarse Estimation of Physical Parameters of Eclipsing Binaries by Means of Automative Scripting
Because of GAIA’s estimated harvest of ∼ 10 eclipsing binaries (Munari et al. 2001) automative procedures for extracting physical parameters from observations must be introduced. We present preliminary results of automative scripting applied to 5 eclipsing binaries, for which photometric and radial velocity observations were taken from literature. Although the results are encouraging, extensive...
متن کاملAbsolute 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 کاملOrbital period changes and the higher-order multiplicity fraction amongst SuperWASP eclipsing binaries⋆
Orbital period changes of binary stars may be caused by the presence of a third massive body in the system. Here we have searched the archive of the Wide Angle Search for Planets (SuperWASP) project for evidence of period variations in 13 927 eclipsing binary candidates. Sinusoidal period changes, strongly suggestive of third bodies, were detected in 2% of cases; however, linear period changes ...
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 ...
