Spectroscopy of Bright QUEST RR Lyrae Stars: Velocity Substructures toward Virgo
A. Katherina Vivas, Yara Jaffe, Robert Zinn +3
Using a sample of 43 bright (V<16.1, distance <13 kpc) RR Lyrae stars (RRLS) from the QUEST survey with spectroscopic radial velocities and metallicities, we find that several sepa…
Spectroscopy of QUEST RR Lyrae Variables: the new Virgo Stellar Stream
Sonia Duffau, Robert Zinn, A. Katherina Vivas +4
Eighteen RR Lyrae variables (RRLs) that lie in the "$12\fh 4$ clump" identified by the QUEST survey have been observed spectroscopically to measure their radial velocities and meta…
The Chemical Enrichment History of the Fornax Dwarf Spheroidal Galaxy from the Infrared Calcium Triplet
Frederic Pont, Robert Zinn, Carme Gallart +2
Near infrared spectra were obtained for 117 red giants in the Fornax dwarf spheroidal galaxy with the FORS1 spectrograph on the VLT, in order to study the metallicity distribution…
