A recent survey of a large sample of massive Galactic asymptotic giant branch (AGB) stars shows that significant overabundances of rubidium (up to 100 times solar), but merely solar zirconium, are present in these stars. These observations can set constraints on our theoretical notion of the slow neutron capture process (the s process) in AGB stars

We present measurements for all objects for which we were able to derive secure redshifts. This includes galaxies belonging to the six aforementioned clusters, four serendipitously found groups and the general field (see the paper and below). For each object, table3.dat provides the identification code, membership, right ascension and declination

Eleven 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 in

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 maximum

We 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 morphological
