The Mass-Radius(-Rotation?) Relation for Low-Mass Stars
Mass-Radius Relation Low-Mass Stars
2010/11/15
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 ...
HIFLUGCS: Galaxy Cluster Scaling Relations between X-ray Luminosity, Gas Mass, Cluster Radius, and Velocity Dispersion
Cosmology observations — (Cosmology:) dark matter — Galaxies clusters: general — Methods
2010/11/15
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and between cluster radius and velocity dispersion (r500 − )...

2010/11/9
The caustic technique uses galaxy redshifts alone to measure the escape velocity and mass profiles of galaxy clusters to clustrocentric distances well beyond the virial ra-dius, where dynamical equili...

2010/11/9
The recent detection of the transit of very massive substellar companions (Deleuil et al. 2008; Bouchy et al. 2010;Anderson et al. 2010; Bakos et al. 2010) provides a strong con-
straint to planet an...
A precise asteroseismic age and radius for the evolved Sun-like star KIC 11026764
