HST Photometry for the Halo Stars in the Leo Elliptical NGC 3377
W. E. Harris, G. L. H. Harris, A. C. Layden +1
We have used the ACS camera on HST to obtain (V,I) photometry for 57,000 red-giant stars in the halo of the Leo elliptical NGC 3377. We use this sample of stars to derive the metal…
The Leo Elliptical NGC 3379: A Metal-Poor Halo Emerges
W. E. Harris, G. L. H. Harris, A. C. Layden +1
We have used the ACS camera on HST to obtain (V,I) photometry for 5300 red-giant stars in the halo of the dominant Leo-group member NGC 3379, a galaxy usually regarded as a classic…
The Metallicity Distribution in the Outer Halo of M33
R. Scott Brooks, Christine D. Wilson, William E. Harris
We present the results of deep I and V-band photometry of the halo stars near the southeast minor axis of the Local Group spiral galaxy M33. An (I,V-I) color-magnitude diagram dist…
