The catalog of radial velocity standard stars for the Gaia RVS: status and progress of the observations
Galaxy Astrophysics (astro-ph.GA) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
A new full-sky catalog of Radial Velocity standard stars is being built for the determination of the Radial Velocity Zero Point of the RVS on board of Gaia. After a careful selection of 1420 candidate...
Towards a new full-sky list of radial velocity standard stars
Galaxy Astrophysics (astro-ph.GA) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The calibration of the Radial Velocity Spectrometer (RVS) onboard the ESA Gaia satellite (to be launched in 2012) requires a list of standard stars with a radial velocity (RV) known with an accuracy o...
Radial Velocity and Metallicity of the Globular Cluster IC4499 Obtained with AAOmega
Galaxy Astrophysics (astro-ph.GA)
2010/12/23
We present radial velocity and metallicity measurements for the far-southern Galactic globular cluster IC4499. We selected several hundred target red giant stars in and around the cluster from the 2MA...
