CALIBRATING THE UPDATED OVERSHOOT MIXING MODEL ON ECLIPSING BINARY STARS: HY Vir, YZ Cas, χ2 Hya, and VV Crv [PDF]
, 2014 Detached eclipsing binary stars with convective cores provide a good tool to investigate convective core overshoot. It has been performed on some binary stars to restrict the classical overshoot model which simply extends the boundary of the fully mixed ...

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.

The massive multiple system HD 64315 [PDF]
, 2017 The O6 Vn star HD 64315 is believed to belong to the star-forming region known as NGC 2467, but previous distance estimates do not support this association.

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.

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 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 ...

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.

Calibrating convective-core overshooting with eclipsing binary systems. The case of low-mass main-sequence stars [PDF]
, 2016 In a robust statistical way, we quantify the uncertainty that affects the calibration of the overshooting efficiency parameter $\beta$ that is owing to the uncertainty on the observational data in double-lined eclipsing binary systems.

LTD064402+245919, Compact Binary or Subgiant with Red Star Eclipsing Binary?
Research Notes of the AAS, 2022 Abstract Recently, a single-line spectroscopic binary, LTD064402+245919, has been discovered by Yang et al. Using data from LAMOST and ZTF, the unseen companion is estimated to have a mass of 1–3 M ⊙, orbiting a subgiant with orbital period of 14.50 days, making it a good compact binary candidate without X-ray emission.
