Eccentric Eclipsing Binary YY Sagittarii
Astrophysics and Space Science, 2006 Seven new precise times of minimum light have been gathered for the triple eccentric eclipsing binary YY Sgr (P = 2d.63, e = 0.16). Its O-C diagram is presented and improved elements of the apsidal motion and the light-time effect are given. We found a new short period of the third body of about 18.5 years in an eccentric orbit (e 3 ≃ 0.4).

Observations of Two Unusual Eclipsing Binaries, FN Cam and AG Vir
Open Astronomy, 2014 Based on the results of classification of eclipsing binaries, we have compiled a list of stars that are promising objects for future study. We have started an observational campaign with telescopes of the Kourovka Observatory, Russia and present the ...

A Statistical Study of the O’Connell Effect in Eclipsing Binaries from the ASAS-SN Survey
The Astrophysical Journal Supplement SeriesThe O’Connell effect is characterized by unequal maxima in the light curve of eclipsing binaries, while its physical origin remains unclear. The All-Sky Automated Survey for Supernovae provides more than a decade of all-sky monitoring data, including 154,

Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations
The Astrophysical JournalEclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

Two hot pre-white dwarfs inside the red giant branch planetary nebula Pa 13
Astronomy & AstrophysicsThe close binary central stars of planetary nebulae (PNe) offer a unique window for investigating the conditions that immediately follow the ejection of a common envelope (CE). Double-eclipsing and double-lined double systems are particularly valuable as

Pulsations in close binaries: challenges and opportunities
EPJ Web of Conferences, 2015 CoRoT and Kepler provided a precious by-product: a number of eclipsing binaries containing variable stars and, among these, non-radial pulsators. This providential occurrence allows combining independent information from two different phenomena whose ...

Contact-binary Evolution with Energy Transfer and Saturated Magnetic Braking
The Astrophysical JournalThe evolution of low-mass contact binaries is influenced by angular momentum loss, mass and energy transfer (ET), and the nuclear evolution of the components.
