Mid-UV Determination of Elliptical Galaxy Abundances and Ages
Jennifer M. Lotz, Henry C. Ferguson, Ralph C. Bohlin
We investigate the effects of abundance and age on the mid-UV spectra and Mg_{2} strengths of stellar populations using simple population synthesis models. These models are used to…

The White Dwarf Distance to the Globular Cluster NGC 6752 (and its Age) with the Hubble Space Telescope (Based on observations made with the NASA/ESA Hubble Space Telescope (HST))
Alvio Renzini, Angela Bragaglia, Francesco R. Ferraro +6
Deep Hubble Space Telescope (HST) observations with WFPC2 of the nearby globular cluster NGC 6752 have allowed us to obtain accurate photometry for the cluster white dwarfs (WD). A…
