CALIBRATING THE UPDATED OVERSHOOT MIXING MODEL ON ECLIPSING BINARY STARS: HY Vir, YZ Cas, χ2 Hya, and VV Crv [PDF]

open access: yes, 2014
Detached eclipsing binary stars with convective cores provide a good tool to investigate convective core overshoot. It has been performed on some binary stars to restrict the classical overshoot model which simply extends the boundary of the fully mixed ...

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.

A CONSTRUCTION OF A SEMI-AUTOMATIC TELESCOPE FOR ECLIPSE TIMING OBSERVATIONS OF ECLIPSING BINARY STARS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
We constructed the photometric observation system with a small semi-automatic telescope for the systematic observations of eclipse timings of eclipsing binary stars.

Space-Based Photometry of Binary Stars: From Voyager to TESS

open access: yesUniverse, 2021
Binary stars are crucial laboratories for stellar physics, so have been photometric targets for space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968.

Multi‐proxy reconstruction of the Holocene vegetation and land use dynamics in the Julian Alps, north‐west Slovenia

open access: yesJournal of Quaternary Science, Volume 38, Issue 1, Page 107-122, January 2023., 2023
Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...

Hidden Companions Detected by Asteroseismology. I. Two Kepler Field Non-Eclipsing Binaries

open access: yesUniverse, 2022
The Kepler space telescope has detected a large number of variable stars. We summarize 2261 δ Scuti and hybrid variables in the literature, and perform time-frequency analysis on these variable stars. Two non-eclipsing binary systems, KIC 5080290 and KIC

Eclipsing Binary Stars from Space [PDF]

open access: yes, 2006
We have begun a programme to obtain high-precision photometry of bright detached eclipsing binary (dEB) stars with the Wide field InfraRed Explorer (WIRE) satellite. Due to the small aperture of WIRE only stars brighter than V=6 can be observed.

Eclipsing binary stars in the Large Magellanic Cloud. Results from the EROS-2, OGLE and VMC surveys ⋆ [PDF]

open access: yes, 2014
We present a catalogue of 1768 eclipsing binary stars (EBs) detected in the Large Magellanic Cloud (LMC) by the second generation of the EROS survey (hereinafter EROS-2); 493 of them are new discoveries located in outer regions (out of the central bar ...

Calibrating convective-core overshooting with eclipsing binary systems. The case of low-mass main-sequence stars [PDF]

open access: yes, 2016
In a robust statistical way, we quantify the uncertainty that affects the calibration of the overshooting efficiency parameter $\beta$ that is owing to the uncertainty on the observational data in double-lined eclipsing binary systems.

A Comprehensive Catalog of Galactic Eclipsing Binary Stars with Eccentric Orbits Based on Eclipse Timing Diagrams

open access: yes, 2018
A comprehensive catalog of 623 galactic eclipsing binary (EB) systems with eccentric orbits is presented with more than 2830 times of minima determined from the archived photometric data by various sky-survey projects and new photometric measurements ...
