Detection of Dark Companions via The Combination of Eclipse Timing Variation, Hipparcos, and/or Gaia Astrometry: The Cases of V Puppis and CY Ari

The Astrophysical Journal
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around eclipsing binaries through the combined analysis of eclipse timing ...

Half a Million Binary Stars Identified from the Low-resolution Spectra of LAMOST

The Astrophysical Journal Supplement Series
Binary stars are prevalent yet challenging to detect. We present a novel approach using convolutional neural networks (CNNs) to identify binary stars from low-resolution spectra obtained by the LAMOST survey.

The Eclipsing Novalike Cataclysmic Variable CRTS SSS100505 J093417-174421

The Astrophysical Journal
Time-resolved optical photometry, complemented by Transiting Exoplanet Survey Satellite (TESS) data and long-term survey light curves, reveals that the transient object CRTS SSS100505 J093417-174421 is an eclipsing novalike cataclysmic variable of the VY

The connection between Delta Scuti stars and close binary parameters

, 2011
With recent advances in CCD technology, it has become possible to detect low-amplitude variability in stars. Thus, the number of low-amplitude variables has increased at an exceptional rate over the past decade.

KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasiperiodic Out-of-eclipse Modulations

The Astrophysical Journal
We present the first detailed analysis of the solar-type triple system KIC 6464285. Combining long-term, high-precision photometry from Kepler, the Transiting Exoplanet Survey Satellite, and the Zwicky Transient Facility with low-resolution spectra from ...

Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics

, 2012
Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities, of ...

The Benchmark Eclipsing Binary V530 Ori : A Critical Test of Magnetic Evolution Models for Low-Mass Stars

, 2015
We report accurate measurements of the physical properties (mass, radius, temperature) of components of the G+M eclipsing binary V530 On. The M-type secondary shows a larger radius and a cooler temperature than predicted by standard stellar evolution ...
