The Pattern of CN, O, and Na Inhomogeneities on the Red Giant Branch of Messier 5
Graeme H. Smith, Payal N. Modi, Katherine M. Hamren
Data from the literature are used to explore the relation between 3883 CN band strength and the sodium and oxygen abundances of red giants in the globular cluster Messier 5. Alt…
HST/WFC3 Observations of Low-Mass Globular Clusters AM 4 and Palomar 13: Physical Properties and Implications for Mass Loss
Katherine M. Hamren, Graeme H. Smith, Puragra GuhaThakurta +4
We investigate the loss of low-mass stars in two of the faintest globular clusters known, AM 4 and Palomar 13 (Pal 13), using HST/WFC3 F606W and F814W photometry. To determine the…
Carbon in the Draco Dwarf Spheroidal Galaxy
Matthew D. Shetrone, Graeme H. Smith, Laura M. Stanford +2
Measurements of [C/Fe], [Ca/H], and [Fe/H] have been derived from Keck I LRISb spectra of 35 giants in the Draco dwarf spheroidal galaxy. The iron abundances are derived by a spect…
Chemical evolution in star clusters: the role of mass and environment
Sarah L. Martell, Sonia Duffau, Antonino P. Milone +3
The process of chemical self-enrichment in stellar systems can be affected by the total mass of the system and the conditions of the large-scale environment. Globular clusters are…
