Nope, I do not think this method is going to be as productive as
zircon dating or core dating
or radioactive element abundance. The trouble with twin stars as much
of astronomy has the trouble
of such huge distances away and the unwarranted assumptions that goes
into the data. When
astronomy can not tell whether a star is a binary system in many
cases, then that leads
to little confidence on my part that binary stars can tell us age
differences.

If we find a zircon crystal from Vesta asteroid that measures the age
of the Solar System at
8 billion years old is about the best evidence we can find. Or if we
find Earth having twice
as much radioactive elements like thorium or uranium than does Jupiter
in parts per billion
would be strong evidence.

Another search for ages of companion stars in binary systems

One of those sites mentions an age difference of 1 billion years of
companion stars.
But that is not a large enough difference for what I am looking for.

So I think that binary stars can be supporting evidence that Earth is
twice as old
as Jupiter, but I suspect binary star studies cannot be the primary
lead evidence.
