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…
Time Domain Explorations With Digital Sky Surveys
A. A. Mahabal, S. G. Djorgovski, M. J. Graham +17
One of the new frontiers of astronomical research is the exploration of time variability on the sky at different wavelengths and flux levels. We have carried out a pilot project us…
Exploring the Time Domain with the Palomar-QUEST Sky Survey
A. Mahabal, S. G. Djorgovski, M. J. Graham +16
Exploration of the time variability on the sky over a broad range of flux levels and wavelengths is rapidly becoming a new frontier of astronomical research. We describe here brief…
