Kepler Eclipsing Binaries with Stellar Companions [PDF]
arXiv, 2015 Many short-period binary stars have distant orbiting companions that have played a role in driving the binary components into close separation. Indirect detection of a tertiary star is possible by measuring apparent changes in eclipse times of eclipsing binaries as the binary orbits the common center of mass.

X-ray reprocessing: Through the eclipse spectra of high mass X-ray binaries with XMM-Newton [PDF]
, 2019 The study of X-ray reprocessing is one of the key diagnostic tools to probe the environment in X-ray binary systems. One difficult aspect of studying X-ray reprocessing is the presence of much brighter primary radiation from the compact star together with the reprocessed radiation. In contrast for eclipsing systems, the X-rays we receive during eclipse

On The Period Determination of ASAS Eclipsing Binaries
, 2013 Variable stars, or particularly eclipsing binaries, are very essential astronomical occurrence. Surveys are the backbone of astronomy, and many discoveries of variable stars are the results of surveys.

β Cephei Pulsators in Eclipsing Binaries Observed with TESS
The Astrophysical Journal Supplement SeriesThe combined strength of asteroseismology and empirical stellar basic parameter determinations for in-depth asteroseismic analysis of massive pulsators in eclipsing binaries shows great potential for treating the challenging and mysterious discrepancies ...

Photometric sample of early B-type pulsators in eclipsing binaries observed with TESS [PDF]
Contributions of the Astronomical Observatory Skalnate Pleso,
54(2): 70-74 (2024)Asteroseismology coupled with eclipsing binary modelling shows a great potential in improving the efficiency of measurements or calibrations of the interior mixing profile in massive stars. This helps, for instance in treating the challenging and mysterious discrepancies between observations and models of its stellar structure and evolution. This paper

Eclipsing Binaries in the Young LMC Cluster NGC 1850 [PDF]
, 2004 I present light curves for two detached eclipsing binary stars in the region of the LMC cluster NGC 1850, which is possibly a young globular cluster still in formation. One, a likely spectral type O star, is a newly detected eclipsing binary in the region of the very young subcluster NGC 1850A.

VW LMi: tightest quadruple system known. Light-time effect and possible secular changes of orbits
, 2008 Tightest known quadruple systems VW LMi consists of contact eclipsing binary with P_12 = 0.477551 days and detached binary with P_34 = 7.93063 days revolving in rather tight, 355.0-days orbit.
