This is the assessement of the current literature on Binary Stars.
That the majority of stars discovered are in
a Binary system and of those more than 60%% are stars whose companion
has a differential age. Why the
astronomers have not met in a colloquim and announced those findings
is unknown as to their "excuses".
Perhaps they are too timid, too shy, too scared to make known what the
overall picture about the age
of stars in binary systems.

Since they are too timid, I will do their job for them.

Most stars are locked in a binary star relationship where they are
gravitationally locked to one another.
The data suggests that 60 percent to 70 percent of all stars are two
star binaries. And of those
two star binaries, 90 percent of them have differential ages where one
of them is about twice or 2X as
old as the other star.

Soon after proposing this "extraordinary wind" (or X-wind) model,
Shu's team realized that the same
violent interactions might be responsible for producing both the CAIs
and the chondrules in the solar
nebula. The interface between the surface of the protostar and the
inner edge of the accretion disk
was just the right temperature to produce these meteoritic inclusions.
Moreover, these winds could
then toss the finished products out to about 3 to 10 AU, where they
would be incorporated into
accreting planetesimals and become part of some planet or asteroid.

But when Sean Ryan, of the University of Texas, and his associates
pointed a telescope at HD 140283,
an ancient star 200 light- years away, they saw ten times more
beryllium than could be accounted for
by the amount of cosmic rays that are coursing through our galaxy
today. Meanwhile, Douglas Duncan,
of the Space Telescope Science Institute, and his colleagues were
pointing the Hubble Telescope at
the same star. They found it contained uncommonly high levels of
boron.

Well, I was really searching for reports of an oversupply of lithium,
beryllium, and boron on the
Comets when I ran across the above.
