Themis family, 2:1 resonace and possible Yarkovsky-driven injection of
asteroids on stable islands?
r21-2 integration: real asteroids inside 2:1 -
15 Griguas
(unstable over ~10 Myr)
and 19 Zhongguos
(stable for 200 Myr) -
integrated for 100 Myr with Yarkovsky effect (C-type thermal parameters
and random orientations of spin axes).
- cmp mean a(t) and proper
("minimum" averaging due to ~400 yr fast ~0.01 AU oscillations of semimajor
axis)
- maximum averaging
- discarded TP's
- ls -lR tmp/r21-2/
- (a, e) plane
2DO: compute lifetimes of individual objects and compare them with
integration r21-1 without Yarkovsky. (Does thermal drag affect
(un)stability of orbits inside 2:1?)
