"Alien civilization still on the table"?
Somehow I doubt an advanced alien
civilization would screw around with
their own star. They might, if they
were less than scrupulous, do it to
somebody else's star. Or maybe they
have found a way to continously
extract energy from a nearby unused
star over many centuries. You could
call them "star eaters."

Once you pass over purely physical
causes and move on to alien activity,
almost anything is possible. There are
physical explanations (some of them
pretty exotic) for the behavior. Maybe
this star swallowed a cloud of small
black holes which orbit inside of it
(or pass through it) and are slowly
"eating" the star.

Since the behaviour has been obseved
in only ONE star, it's could be very
exotic (as exotic events are likely to
be very rare). Now, if you find
thousands more... that's a problem.
