2017/9/5
A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White...

We have identified a star in the WASP archive photometry with an unusual lightcurve due to the total eclipse of a small, hot star by an apparently normal A-type star and with an orbital period of only...

We have discovered a detached pair of white dwarfs (WDs) with a 12.75 min orbital period and a 1,315 km/s radial velocity amplitude. We measure the full orbital parameters of the system using its ligh...
Light Curve Analysis of Hipparcos Data for the Massive O-type Eclipsing Binary UW CMa

2010/11/11
Hipparcos photometric data for the massive O-type binary UWCMa were analysed within the framework of the Roche model. Photometric solutions were obtained for five mass ratios in the q = M2/M1 = 0.5 &#...

Binaries are not always neatly aligned. Previous observations of the DI Her system showed that the spin axes of both stars are highly inclined with respect to one another and the orbital axis. Here we...

We propose a procedure for light-curve solution of eclipsing bi-nary stars in the Small Magellanic Cloud for which photometric data have been obtained in the framework of the OGLE project as well as w...
Photometric study of two beta Cephei pulsators in eclipsing systems

2010/12/24
We present results of a photometric study of the young southern open cluster Stock 14. This cluster is known to contain two eclipsing systems with presumed beta Cephei components, HD 101794 and HD 101...
