The Space Interferometry Mission Astrometric Grid Giant-Star Survey. I. Stellar Parameters and Radial Velocity Variability
Dmitry Bizyaev, Verne V. Smith, Jose Arenas +7
We present results from a campaign of multiple epoch echelle spectroscopy of relatively faint (V = 9.5-13.5 mag) red giants observed as potential astrometric grid stars for the Spa…
Low Mass X-ray Binaries in 6 Elliptical Galaxies: Connection to Globular Clusters
Eunhyeuk Kim, Dong-Woo Kim, Giuseppina Fabbiano +4
We present a systematic study of the low mass X-ray binary (LMXB) populations of 6 elliptical galaxies. We utilize Chandra archival data to identify 665 X-ray point sources and HST…
A photometric study of the old open clusters Berkeley 73, Berkeley 75 and Berkeley 25
G. Carraro, D. Geisler, A. Moitinho +2
CCD BVI photometry of the faint open clusters Berkeley~73, Berkeley~75 and Berkeley~25 are presented. The two latter are previously unstudied clusters to our knowledge. While Berke…
Extragalactic Globular Clusters in the Near-Infrared: V. IC 4051 and NGC 3311
M. Hempel, D. Geisler, D. W. Hoard +1
We present the results of combined optical and near-infrared photometry for the globular cluster systems of the giant ellipticals IC 4051 and NGC 3311. We use the reduced age-metal…
Exploring Halo Substructure with Giant Stars. VI. Extended Distributions of Giant Stars Around the Carina Dwarf Spheroidal Galaxy -- How Reliable Are They?
S. R. Majewski, P. M. Frinchaboy, W. E. Kunkel +6
The question of the existence of active tidal disruption around various dSph galaxies remains controversial. That debate often centers on the nature (bound vs. unbound) of extended…
The intermediate-age open clusters Ruprecht 4, Ruprecht 7 and Pismis 15
Giovanni Carraro, Doug Geisler, Gustavo Baume +2
We report on CCD photometry to for 3 fields centered on the region of the Galactic star clusters Ruprecht~4, Ruprecht~7 and Pismis~15 and on 3 displaced control fiel…
