Short-period Heartbeat Binaries from TESS Full-frame Images

The Astrophysical Journal Supplement Series
We identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...

Light curve analysis of eclipsing binary stars using PHOEBE [PDF]

publisherClose binary stars are important sources of astronomical information. Photometric data can be acquired from these stars using a small-aperture telescope, and the period, radius ratio, and ratio of the luminous intensities of the component stars ...

A Systematic Search for Big Dippers in ASAS-SN

The Open Journal of Astrophysics
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplanetary evolution or stellar winds.

A Bright Short Period M-M Eclipsing Binary From The KELT Survey: Magnetic Activity And The Mass–Radius Relationship For M Dwarfs [PDF]

, 2017
We report the discovery of KELT J041621-620046, a moderately bright (J ~ 10.2) M-dwarf eclipsing binary system at a distance of 39 ± 3 pc. KELT J041621-620046 was first identified as an eclipsing binary using observations from the Kilodegree Extremely ...

ECLIPSING BINARY STARS : LIGHT CURVE MODELS AND SOFTWARE

Odessa Astronomical Publications, 2017
The importance of studying Eclipsing Binary Stars for the determination of fundamental stellar data is sketched. The eclipsing binaries, originally classified phenomenologically, are now understood on the basis of much firmer physics and the improved ...

The period distribution of close binary systems

, 1979
The analysis of the period distribution of eclipsing and spectroscopic binary systems shows the presence of some secondary maxima, which cannot depend on selection effects. These secondary maxima are mainly due to late type stars, as can be seen from the

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days

The Astrophysical Journal
We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.
