VizieR Online Data Catalog: γ Cas radial velocity curve (Smith+, 2012)

Our LBOI observations were conducted in the infrared using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) array facility on Mt. Wilson. CHARA is an interferometric array of six 1-m telescopes configured in a Y-shaped pattern with baselines of up to 330m for maximum spatial resolution. Our observations utilized two new-generation instruments for imaging of γ Cas's decretion disk: the Michigan Infrared Combiner (MIRC) in the H-band (1.64um) and the Visible spEctroGraph and polArimeter (VEGA), which became operational in 2009.

Our optical continuum observations of γ Cas were made in the standard Johnson V and B band filters on every available photometric night (sometimes several times per night) using the 0.4m T3 Automated Photometric Telescope (APT) located at Fairborn Observatory in the Patagonia mountains in southern Arizona.

To support this program we made use of 306 echelle spectra of γ Cas taken in a long-term monitoring program with the spectrograph fiber-fed from the Cassegrain focus of the 1.06-m telescope at Ritter Observatory (administered by the University of Toledo) in 2009 December and the second half of 2010.

We conducted four XMM-Newton observations under the auspices of Guest Investigator cycle A09. These were carried out on 2010 July 7 (ObsID 0651670201; referred to here as OBS1), July 24 (0651670301; OBS2), August 2 (0651670401; OBS3), and August 24 (0651670501; OBS4), beginning on MJD dates 55384.30, 55401.15, 55410.77, and 55428.09, respectively.
