A Search for Exoplanets in Short-Period Binary Star Systems [PDF]
Journal of Astronomy and Space Sciences, 2012 This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

Mass Transfer in Binary Stars using Smoothed Particle Hydrodynamics [PDF]
, 2010 Despite numerous efforts to better understand binary star evolution, some aspects of it remain poorly constrained. In particular, the evolution of eccentric binaries has remained elusive mainly because the Roche lobe formalism derived for circular ...

Five New Sirius-like White Dwarf–Main-sequence Star Systems with MagAO-X
The Astronomical JournalMost known white dwarfs in multiple systems with main-sequence stars have been discovered with M-type companions, because the white dwarf causes detectable UV excess and bluer colors than expected from a single M star.

Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network
The Astronomical JournalA contact binary may be the progenitor of a red nova that eventually produces a merger event and have a cut-off period of around 0.2 days. Therefore, a large number of contact binaries is needed to search for the progenitor of red novae and to study the ...

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

Spectroscopic Orbits of Subsystems in Multiple Stars. XI
The Astronomical JournalAdding to the large radial velocity survey of nearby solar-type stars (summary in Tokovinin, 2023a), spectroscopic orbits are determined for four hierarchical systems: HIP 49442 (inner and outer periods of 164.55 days and 34 yr, respectively), HIP 55691 (
