We present deep optical images of the historical X-ray Transient KY TrA in quiescence from which we confirm the identification of the counterpart reported by Murdin et al. and derive an improved position of α = 15:28:16.97 and δ = -61:52:57.8. In 2007 June we obtained I, R and V images, where the counterpart seems to be double indicating the

We present the first detailed abundance analysis of the metal-poor giant HK-II 17435-00532. This star was observed as part of the University of Texas Long-Term "Chemical Abundances of Stars in the Halo" (CASH) Project. A spectrum was obtained with the High Resolution Spectrograph (HRS) on the Hobby-Eberly Telescope with a resolving power of R 15

We introduce the The Hobby-Eberly Telescope Chemical Abundances of Stars in the Halo (CASH) Project. This University of Texas Long Term Project aims at discovering metal-poor Galactic halo stars selected from various surveys. We present the results of the first year of HET observations: Thus far, 200 objects are observed with the high-resolution

We present scaling relations between structural properties of nuclear star clusters and their host galaxies for a sample of early-type dwarf galaxies observed as part of the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) Coma Cluster Survey. We have analysed the light profiles of 200 early-type dwarf galaxies in the magnitude range

The HST/ACS GGC Survey provides reliable photometry from 6 magnitudes below the main sequence turn-off to the level of the horizontal branch ( 3.5 magnitudes brighter than the turn-off) for 65 Galactic globular clusters. The absolute ages of a sub-sample of those clusters, which have low reddenings and well determined chemical compositions, have
