cds-question@unistra.frbe-starsemission-line-starsradial-velocity{gamma} Cas is the prototypical classical Be star and is recently best known for its variable hard X-ray emission. To elucidate the reasons for this emission, we mounted a multiwavelength campaign in 2010 centered around four XMM-Newton observations. The observational techniques included long baseline optical interferometry (LBOI) from two instruments at CHARA, photometry carried out by an automated photometric telescope and H{alpha} observations. Because {gamma} Cas is also known to be in a binary, we measured radial velocities from the H{alpha} line and redetermined its period as 203.55+/-0.20 days and its eccentricity as near zero.2012A&A...540A..53Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/540/A53CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/284/515 : Long-term periodic variability in gamma Cas (Telting+ 1994)J/ApJ/647/1375 : BV light curves of {gamma} Cas (Smith+, 2006)J/A+A/537/A59 : Radial velocities of gamma Cas (Nemravov+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/540/A53https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/540/A53http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/540/A53https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/540/A53https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/540/A53http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/540/A53GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/540/A53/table2Ritter and Dobson/RB radial velocitiesrecnoRecord number assigned by the VizieR team.
