Default binaries with visible matter exchange?

well, the subject says it all: are there binaries with visible matter
exchange?

No, they're too close to resolve.

Of course if he/she means "detectable" mass exchange just about any
close binary would qualify - spectroscopic binaries, eclipsing
variables, novae, and so on.

I meant visible detection.

Interestingly, the two components of Sirius must have exchanged mass in the
past, because the less massive star (the white dwarf) is the most highly
evolved. If anyone had been around then and the distance was still around 8
light years, that might have been seen visually with a scope.

Generally though, visual doubles are really quite distant with periods of
hundreds or thousands of years. The greater the separation, the larger the
Rouche lobe that would have to be filled before matter could spill over to
the other star. The matter basically has to make it out to the Lagrange
point between the two, where the gravitational pulls are balanced.
