Long-term investigation of gamma Cas analogs
Yael Naze, Gregor Rauw, Robbie Webbe +2
The subcategory of gamma Cas analogs gathers Be stars with bright and hard X-ray emission. Long-term variations are expected in such objects for two reasons: their Be disk builds a…
X-raying the zeta Tau binary system
Yael Naze, Christian Motch, G. Rauw +2
The Be star zeta Tau was recently reported to be a gamma Cas analog; that is, it displays an atypical (bright and hard) X-ray emission. The origin of these X-rays remains debated.T…
The X-ray emission of gamma Cassiopeiae during the 2020-2021 disc eruption
Gregor Rauw, Yaël Nazé, Christian Motch +3
gamma Cas is known for its hard and intense X-ray emission that could trace accretion by a compact companion, wind interaction with a hot sub-dwarf companion, or magnetic interacti…
Automated photometry of Cassiopeiae:the last roundup
Myron A. Smith, G. W. Henry
Gamma Cas (B0.5IVe) is the noted prototype of a subgroup of classical Be stars exhibiting hard thermal X-ray emission. This paper reports results from a 23-year optical campaign wi…
Surprises in the simultaneous X-ray and optical monitoring of pi Aqr
Yael Naze, G. Rauw, M. Smith
To help constrain the origin of the peculiar X-ray emission of gamma Cas stars, we conducted a simultaneous optical and X-ray monitoring of pi Aqr in 2018. At that time, the star a…
Intriguing X-ray and optical variations of the gamma Cas analog HD45314
G. Rauw, Y. Nazé, M. A. Smith +11
A growing number of Be and Oe stars, named the gamma Cas stars, are known for their unusually hard and intense X-ray emission. This emission could either trace accretion by a compa…
