[vsnet-chat 713] CVs in triple systems?

[Alon Retter <alon@wise.tau.ac.il>]

Dear Timo,

To my knowledge, when you add a third companion nearby a CV system, it
becomes unstable. Thus, it can be placed only at much larger distances
from the binary system (when the gravitational forces of the two act like
those of a single star). As you wrote, I don't think that such a triplet
has been detected so far. 

Best wishes,
Alon Retter
