Chemical Abundances in the Carina dSph Galaxy
Tammy A. Smecker-Hane, Georgi I. Mandushev, James E. Hesser +3
We report on the chemical abundances of stars in the Carina dwarf spheroidal galaxy (dSph) derived from low-resolution spectra. We have determined values of [Fe/H] for 52 stars fro…
Blue Horizontal--Branch Stars: The "Jump" in Stromgren u, Low Gravities, and Radiative Levitation of Metals
F. Grundahl, M. Catelan, W. B. Landsman +3
We study the ``jump'' in the blue horizontal--branch (BHB) distribution first detected by Grundahl et al. (1998) in the Galactic globular cluster (GC) M13. On the basis of Stromgre…
Exploring Star Clusters Using Stromgren uvby Photometry
F. Grundahl, D. A. VandenBerg, P. B. Stetson +3
We illustrate the application of high precision Stromgren uvby photometry to open and globular clusters (GCs). It is shown how such data can be used to determine cluster ages, inde…
The Hubble Constant from the HST Key Project on the Extragalactic Distance Scale
Laura Ferrarese, Brad Gibson, Daniel Kelson +14
The final efforts of the HST Key Project on the Extragalactic Distance Scale are presented. Four distance indicators, the Surface Brightness Fluctuation method, the Fundamental Pla…
A Cepheid distance to NGC 4258
Eyal Maoz, Jeffrey A. Newman, Laura Ferrarese +5
Distances measured using Cepheid variable stars have been essential for establishing the cosmological distance scale and the value of the Hubble constant. These stars have remained…
