I guess it all boils down to how big of a piece of the star became a
part of the moon.  After all, we're not talking about the whole star,
here.  Also, what would possibly cause a piece of a red, white or brown
dwarf star to become dislodged and travel here?  Pretty much anything
from a kinetic impact with such a star is going to be sucked in by the
star's gravity and become a part of it.  These types of stars aren't
prone to becoming a nova/supernova, so no bits could be cast off by such
an explosion based upon that star alone.  Maybe a collision of galaxies
might cause one of these whole stars to be cast off and coming in our
direction, but that would be the whole star, not a piece.  If, during a
collision, it did break apart, it'd probably coalesce back together and
cool on the long trip here, and when it got here, how would anybody know
it was a piece of a dwarf star?  Maybe during a stellar collision, a
piece might be cast off, but it probably wouldn't have enough mass to
continue to be a star, and would probably coalesce and cool into a
planet or asteroid on the way here.  Their whole story idea seems beyond
far fetched.
