| Abstract |
We study the existence of stable trajectories, where gas could
accumulate to form accretion discs, around stars that form binary
systems in eccentric orbits. Since the potential is time dependent, no
fixed, periodic, close orbits exist. Instead, we search for invariant
loops: closed curves that change shape in synchronism with the binary
orbital phase. Non-intersecting loops can provide the scaffolding for
circumstellar and circumbinary discs in these systems. We investigate
the range of regions in phase space where these non-intersecting loops
can exist and find this to depend on both, the mass ratio of the stars
and their orbital eccentricity, with a strong dependence on the latter.
The recent discovery of planets within close binary systems makes this
work very relevant. |
