The Mass-Radius(-Rotation?) Relation for Low-Mass Stars [PDF]

open access: yes, 2010
The fundamental properties of low-mass stars are not as well understood as those of their more massive counterparts. The best method for constraining these properties, especially masses and radii, is to study eclipsing binary systems, but only a small ...

A catalogue of temperatures for Kepler eclipsing binary stars [PDF]

open access: yes, 2013
We have combined the Kepler Eclipsing Binary Catalogue with information from the HES, KIS and 2MASS photometric surveys to produce spectral energy distribution fits to over 2600 eclipsing binaries in the catalogue over a wavelength range of 0.36–2.16 A ...

Asteroseismology of binary stars and a compilation of core overshoot and rotational frequency values of OB stars [PDF]

open access: yes, 2013
After a brief introduction into the asteroseismic modelling of stars, we provide a compilation of the current seismic estimates of the core overshooting parameter and of the rotational frequency of single and binary massive stars. These important stellar

The Frequency of Binary Stars in the Core of 47 Tucanae

open access: yes, 2001
Differential time series photometry has been derived for 46422 main-sequence stars in the core of 47 Tucanae. The observations consisted of near-continuous 160-s exposures alternating between the F555W and F814W filters for 8.3 days in 1999 July with ...

The massive multiple system HD 64315 [PDF]

open access: yes, 2017
The O6 Vn star HD 64315 is believed to belong to the star-forming region known as NGC 2467, but previous distance estimates do not support this association.

Single‐cell/nanoparticle trajectories reveal two‐tier Lévy‐like interactions across bacterial swarms

open access: yesVIEW, Volume 3, Issue 6, December 2022., 2022
Bacterial community is a typical model system to study the behavior of multicellular organization, how millions of cells are organized, and how they communicate efficiently microscopically on large spatiotemporal scales have attracted a lot of attention.

The Evolution of the Supersoft X-Ray Source WX Cen Dominated by Magnetic Wind

open access: yesThe Astrophysical Journal, 2023
WX Cen is most likely one of the Galactic counterparts of compact binary supersoft X-ray sources as a member of the V Sagittae class, in which mass is transferred from a donor secondary to a massive white dwarf primary via an accretion disk. Based on the

Constraining the Variability and Binary Fraction of Galactic Center Young Stars

open access: yes, 2016
We present constraints on the variability and binarity of young stars in the central 10 arcseconds (~0.4 pc) of the Milky Way Galactic Center (GC) using Keck Adaptive Optics data over a 12 year baseline.

Eclipsing binaries in the MACHO database: New periods and classifications for 3031 systems in the Large Magellanic Cloud [PDF]

open access: yes, 2007
Eclipsing binaries offer a unique opportunity to determine fundamental physical parameters of stars using the constraints on the geometry of the systems. Here we present a reanalysis of publicly available two-color observations of about 6800 stars in the

KEPLER ECLIPSING BINARY STARS. I. CATALOG AND PRINCIPAL CHARACTERIZATION OF 1879 ECLIPSING BINARIES IN THE FIRST DATA RELEASE [PDF]

open access: yes, 2010
The Kepler space mission is devoted to finding Earth-size planets orbiting other stars in their habitable zones. Its large, 105 deg2 field of view features over 156,000 stars that are observed continuously to detect and characterize planet transits. Yet,
