Follow-up observations of Gamma-Cas analogs

GammaCas analogs are early Be stars displaying very unusual hard Xray emissionwith a luminosity intermediate between normal massive stars and XRBs. Both anunexpected magnetic activity in a critically rotating star, or accretion in a Be+ white dwarf (or neutron star) binary, have been invoked to account for theseoutstanding features. We request followup observations to better characterisethe highenergy properties (Xray temperatures, local absorption and variabilitypatterns) of those GammaCas analogs and candidate analogs lacking sensitiveenough observations. The new Xray data together with the existing optical datawill allow us to bring stronger constraints on the Xray emitting mechanism. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
