Journal ArticleDOI
The Formation of Brown Dwarfs as Ejected Stellar Embryos
Bo Reipurth,Cathie J. Clarke +1 more
TL;DR: Brown dwarfs are assumed to be stellar embryos for which the star formation process was aborted before the hydrostatic cores could build up enough mass to eventually start hydrogen burning as discussed by the authors, which explains the rarity of brown dwarfs as close companions to normal stars, the absence of wide brown dwarf binaries, and the flattening of the low mass end of the initial mass function.

Revised rates of stellar disruption in galactic nuclei
Jianxiang Wang,David Merritt +1 more
TL;DR: In this paper, the authors compute rates of tidal disruption of stars by supermassive black holes in galactic nuclei, using downwardly revised black hole masses from the MBH-σ relation.
Journal ArticleDOI
Ultracold neutral plasmas
TL;DR: In this article, it was shown that strongly coupled plasmas, in which the electrical interaction energy between charged particles exceeds the average kinetic energy, reverse the traditional energy hierarchy underlying basic plasma concepts such as Debye screening and hydrodynamics.

The age of the oldest Open Clusters
TL;DR: In this article, the ages of 71 old Open Clusters were determined by a two-step method: first, main-squence fitting to 10 selected clusters, in order to obtain their distances, and derive their ages from comparison with their own isochrones used before for Globular Clusters.

Star cluster formation and disruption time-scales — I. An empirical determination of the disruption time of star clusters in four galaxies
TL;DR: In this article, the authors derived the disruption times of star clusters from cluster samples of four galaxies, M51, M33, the Small Magellanic Cloud (SMC) and the solar neighbourhood.
