Radial Age and Metal Abundance Gradients in the Stellar Content of M32
James A. Rose, Nobuo Arimoto, Nelson Caldwell +3
We present long-slit spectroscopy of the elliptical galaxy M32, obtained with the 8-m Subaru telescope at Mauna Kea, the 1.5-m Tillinghast telescope at the F. L. Whipple Observator…
The Identification of Blue Horizontal Branch Stars in the Integrated Spectra of Globular Clusters
Ricardo P. Schiavon, James A. Rose, Stephane Courteau +1
A major uncertainty in the spectroscopic dating of extragalactic globular clusters concerns the degenerate effect that age and horizontal branch morphology have on the strength of…
The Indo-U.S. Library of Coude Feed Stellar Spectra
Francisco Valdes, Ranjan Gupta, James A. Rose +2
We have obtained spectra for 1273 stars using the 0.9m Coudé Feed telescope at Kitt Peak National Observatory. This telescope feeds the coudé spectrograph of the 2.1m telescope. Th…
