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

Using data collected as part of the Hubble Space Telescope Advanced Camera for Surveys (ACS) study of Galactic gobular clusters, we present photometry and luminosity functions (LFs) extending several magnitudes below the main sequence turn off for a sample of Galactic globular clusters. These clusters have been selected from the larger ACS survey
