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 کاملA VLT/NACO Survey for Triple and Quadruple Systems among Visual Pre-Main Sequence Binaries
Aims. This paper describes a systematic search for high-order multiplicity among wide visual Pre-Main Sequence (PMS) binaries. Methods. We conducted an Adaptive Optics survey of a sample of 58 PMS wide binaries from various star-forming regions, which include 52 T Tauri systems with mostly Kand M-type primaries, with the NIR instrument NACO at the VLT. Results. Of these 52 systems, 7 are found ...
متن کاملBinaries among Herbig Ae/Be stars
We have studied the circumstellar environment of 31 Herbig Ae/Be and related stars in the near infrared by means of speckle-interferometry. For the brighter objects we reach or approximate diffraction-limited resolution of ≈ 0.1′′ (typically 100 AU at the object). Of the resolved objects some show halos, some have a companion. Here we restrict ourselves to a discussion of binarity in this sampl...
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 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 ...
