[vsnet-be 13] Re: What is V862 Sco?
Okay folks, time to think tangential here...
think on things like V4641 Sgr, the Galactic microquasar, that models of
gamma Cas stars sometimes include binarity, specifically with a neutron
star companion, that although there appears to be no xray source or
radio source, we've got the alignment thingy to consider again, so it
may be our first Galactic microblazar [as worn at Galactic microschools,
no doubt ;)], that this variable is near the heart of Galactic open
cluster M6, in the heart of an OB association, so maybes gravitational
relaxation makes such a situation a bit more likely [though I doubt
that, cos timescale seems far too short: maybe the probability of paired
OB stars being formed with higher frequency in such an area is a better
tack to take here: ?the B star doesn't get slung off during t'other
star's SN event due to sheer mass?].
So, maybes an HMXB without the X?
B1ne stars like V862 Sco are supposed to have circumstellar shells,
almost by definition [indeed I'm not sure where betaCMa=betaCep and Be
stars end and gammaCas stars begin, classification wise], given a
massive companion, the odd TNR could/should occur, though on the other
hand the amplitude here seems a tad wimpish for such, though the usual
"fix" is to blame stellar wind accretion instead of mass transfer for
less energetic events.
