  1. Disks in Eccentric Binary Systems Barbara Pichardo, Linda Sparke &Luis Aguilar (IA- UNAM) (UW- Madison) (OAN) Spherical Cow Dynamicists of Wisconsin

  2. Method of invariant loops finds multiply-periodic 'closed' particle orbits. Gas settles onto stable non-intersecting invariant loops. See our poster, or Pichardo, Sparke & Aguilar 2005: MNRAS, 359, 521

  3. ecc=0.9 peri Circumbinary disks are ‘scared away’ by the small star: they center on its orbit, not the binary’s mass center. Circumstellar disk radius shrinks as (1-e)1.2 ecc=0 apo m1/m2=9

  4. Can use invariant loops to find orbit eccentricity from disk sizes as in L1551, stable zones for planets in binary systems, etc. L1551 disk sizes limit eccentricity and mass ratio: [0.5-m2/(m1+m2)] + 0.5e < 0.1 THE END
