A survey for high-mass eclipsing binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We report results from a search for Galactic high-mass eclipsing binaries. The photometric monitoring campaign was performed in Sloan r and i with the robotic twin refractor RoBoTT at the Universitätssternwarte Bochum in Chile and complemented by Johnson UBV data.

Effects of Mg on Microstructure and Solidification of a Hypereutectic Zn–8 wt.%Al Alloy
Advanced Engineering Materials, EarlyView.An appreciable set of results involving thermal data, microstructure, chemical composition, and microstructural growth laws is reported for ZnAlMg alloys. Such results demonstrate that ZnAlMg alloys have high potential for applications in automotive self‐lubricating components, batteries, and electrical systems.

Open Astronomy, 2017 Planets and brown dwarfs in close orbits will interact with their host stars, as soon as the stars evolve to become red giants. However, the outcome of those interactions is still unclear.

The Eclipses of the Close Binary Star BE UMa [PDF]
International Astronomical Union Colloquium, 1996 BE UMa is a close binary star, not transferring mass, with an extremely hot primary star irradiating the inner face of the cool secondary star. The light curve shows a large-amplitude, sinusoidal variation with a period of 2.29 d, and an eclipse that is centered on the minimum of the variation [1], [3].

Mass Ratio Estimates for Overcontact Binaries Using the Derivatives of Light Curves
The Astrophysical Journal, 2023 The photometric mass ratios of eclipsing binaries are usually estimated by light-curve modeling with an iterative method. We propose a new method for estimating the photometric mass ratio of an overcontact binary using the derivatives of a light curve ...

White dwarfs in the WTS: Eclipsing binaries [PDF]
EPJ Web of Conferences, 2013 We have identified photometric white dwarf candidates in the WFCAM transit survey through a reduced proper motion versus colour approach. Box-fitting with parameters adjusted to detect the unique signature of a white dwarf + planet/brown dwarf transit/eclipse event was performed, as well as looking for variability due to the irradiation of the ...

Notes on the spectra of eclipsing binaries.
The Astronomical Journal, 1950 The writer is engaged in a program of observing eclipsing binaries with the principal aim of obtaining masses and radii of stars of various types. For this purpose it is necessary that radial velocities of both components of a system be obtained.
