On the Anomalous Balmer Line Strengths in Globular Clusters
Violet Poole, Guy Worthey, Hyun-chul Lee +1
Spectral feature index diagrams with integrated globular clusters and simple stellar population models often show that some clusters have weak H beta, so weak that even the oldest…
Comparison of Alpha-Element Enhanced Simple Stellar Population Models with Milky Way Globular Clusters
Hyun-chul Lee, Guy Worthey, Aaron Dotter
We present simple stellar population (SSP) models with scaled-solar and alpha-element enhanced abundances. The SSP models are based on the Dartmouth Stellar Evolution Database, our…
Increasing the Number of Underrepresented Minorities in Astronomy Through K-12 Education and Public Outreach (Paper II)
Dara Norman, CSMA, NSHP +30
In order to attract, recruit and retain underrepresented minority students to pursue Astronomy and related fields, we must ensure that there continues to be a well qualified pool o…
Increasing the Number of Underrepresented Minorities in Astronomy: Executive Summary
Dara Norman, CSMA, NSHP +30
Promoting racial and ethnic diversity is critically important to the future success and growth of the field of astronomy. The raw ability, drive and interest required to excel in t…
Effects of Alpha-Element Enhancement and the Thermally Pulsing-Asymptotic Giant Branch on Surface Brightness Fluctuation Magnitudes and Broadband Colors
Hyun-chul Lee, Guy Worthey, John P. Blakeslee
We investigate the effects of alpha-element enhancement and the thermally pulsing-asymptotic giant branch (TP-AGB) stars on the surface brightness fluctuation (SBF) magnitudes and…
