On the X-ray and optical properties of the Be star HD 110432: a very hard-thermal X-ray emitter
Raimundo Lopes de Oliveira, Christian Motch, Myron A. Smith +3
(ABRIDGED) - HD 110432 is the first proposed, and best studied, member of a growing group of Be stars with X-ray properties similar to gamma Cas. These stars exhibit hard-thermal X…
New Gamma Cas-like objects: X-ray and optical observations of SAO49725 and HD161103
Raimundo Lopes de Oliveira, Christian Motch, Frank Haberl +2
A growing number of early Be stars exhibit unusually hard X-ray spectra and luminosities intermediate between those typical of early type stars and those emitted by most Be/X-ray b…
X-ray and optical properties of new Gamma Cas-like objects discovered in X-ray surveys
Christian Motch, Raimundo Lopes de Oliveira, Ignacio Negueruela +2
A growing number of early Be stars discovered in X-ray surveys exhibit X-ray luminosities intermediate between those of normal stars and those of most Be/X-ray binaries in quiescen…
