Properties of the Coolest DwarfsEleven years after the discovery of the first T dwarf, a population of ultracool L and T dwarfs has been identified that is large enough to show a range of atmospheric properties. Also, model atmospheres are sufficiently advanced to study these properties in detail. Since the last Cool Stars meeting, several observational developments have aided inLeggett, S. et al.

On the masses and evolutionary status of the black hole binary GX 339-4: a twin system of XTE J1550-564?We apply the K-correction to the black hole low-mass X-ray binary (LMXB) GX 339-4 which implies MX >= 6Msolar by only assuming that the companion is more massive than ~0.17Msolar, the lower limit allowed by applying a `stripped-giant' model. This evolutionary model successfully reproduces the observed properties of the system. We obtain a maximumMuñoz-Darias, T. et al.

Neutral and ionized gas dynamics in Blue Compact Dwarf GalaxiesWe propose to carry out full-synthesis (12-h) HI ATCA observations of 6 bright Blue Compact Dwarf Galaxies (BCDGs). The HIPASS data of these objects indicate that they possess a considerable amount of neutral gas. We want to estimate the distribution of the HI in each BCDG and its surrounding, looking for independent HI clouds or morphologicalLopez-Sanchez, Angel R. et al.

Mass Outflow and Chromospheric Activity of Red Giant Stars in Globular Clusters.I. M15High-resolution spectra of 110 selected red giant stars in the globular cluster M15 (NGC 7078) were obtained with Hectochelle at the MMT telescope in 2005 May, 2006 May, and 2006 October. Echelle orders containing Hα and CaII H & K are used to identify emission and line asymmetries characterizing motions in the extended atmospheres. Emission in HαMeszaros, Sz. et al.
