Eclipsing Binary Stars in Nearby Galaxies [PDF]
Astrophysics and Space Science, 2006 We briefly discuss the survey programme we are conducting to detect eclipsing binaries in local group galaxies. Some lightcurves from studies of M31, IC 1613 and NGC 6822 are presented along with details of future work.

Space-Based Photometry of Binary Stars: From Voyager to TESS
Universe, 2021 Binary stars are crucial laboratories for stellar physics, so have been photometric targets for space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968.

The Mass-Radius(-Rotation?) Relation for Low-Mass Stars [PDF]
, 2010 The fundamental properties of low-mass stars are not as well understood as those of their more massive counterparts. The best method for constraining these properties, especially masses and radii, is to study eclipsing binary systems, but only a small ...

Eclipsing binaries with candidate CP stars [PDF]
Astronomy & Astrophysics, 2001 We present a detailed study of an eclipsing binary which had been classied Ap SrCrEu (Hartoog 1976) before being known as a binary. Radial velocities measured at the times of both quadratures allow us to obtain precise masses for both components, while the light curve yields the radii.

Eclipsing binaries in the MACHO database: New periods and classifications for 3031 systems in the Large Magellanic Cloud [PDF]
, 2007 Eclipsing binaries offer a unique opportunity to determine fundamental physical parameters of stars using the constraints on the geometry of the systems. Here we present a reanalysis of publicly available two-color observations of about 6800 stars in the

Eclipsing binary stars in the Large Magellanic Cloud. Results from the EROS-2, OGLE and VMC surveys ⋆ [PDF]
, 2014 We present a catalogue of 1768 eclipsing binary stars (EBs) detected in the Large Magellanic Cloud (LMC) by the second generation of the EROS survey (hereinafter EROS-2); 493 of them are new discoveries located in outer regions (out of the central bar ...

Hidden Companions Detected by Asteroseismology. I. Two Kepler Field Non-Eclipsing Binaries
Universe, 2022 The Kepler space telescope has detected a large number of variable stars. We summarize 2261 δ Scuti and hybrid variables in the literature, and perform time-frequency analysis on these variable stars. Two non-eclipsing binary systems, KIC 5080290 and KIC

The eclipsing binary star RZ Cassiopeiae [PDF]
Astronomy & Astrophysics, 2008 Aims. We test the hypothesis that the oEA star RZ Cas has undergone a transient phase of rapid mass-transfer in 2000/2001. Methods. We analyze a time series of high-resolution spectra of RZ Cas obtained in 2001 and in 2006 for radial velocity (RV) and line profile variations.

The Frequency of Binary Stars in the Core of 47 Tucanae
, 2001 Differential time series photometry has been derived for 46422 main-sequence stars in the core of 47 Tucanae. The observations consisted of near-continuous 160-s exposures alternating between the F555W and F814W filters for 8.3 days in 1999 July with ...
