Shape model and spin state of non-principal axis rotator (5247) Krylov
H. -J. Lee, J. Ďurech, M. -J. Kim +12
Context. The study of non-principal axis (NPA) rotators can provide important clues to the evolution of the spin state of asteroids. However, so far, very few studies have focused…
Asteroid pairs: a complex picture
P. Pravec, P. Fatka, D. Vokrouhlický +45
We studied 93 asteroid pairs. We estimated times elapsed since separation of pair members that are between 7*10^3 and a few 10^6 yr. We derived the rotation periods for all the pri…
YORP and Yarkovsky effects in asteroids (1685) Toro, (2100) Ra-Shalom, (3103) Eger, and (161989) Cacus
J. Durech, D. Vokrouhlicky, P. Pravec +22
The rotation states of small asteroids are affected by a net torque arising from an anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long time…
Spin vector and shape of (6070) Rheinland and their implications
David Vokrouhlicky, Josef Durech, David Polishook +12
Main belt asteroids (6070) Rheinland and (54827) 2001NQ8 belong to a small population of couples of bodies which reside on very similar heliocentric orbits. Vokrouhlicky & Nesvorny…
Combining asteroid models derived by lightcurve inversion with asteroidal occultation silhouettes
Josef Durech, Mikko Kaasalainen, David Herald +9
Asteroid sizes can be directly measured by observing occultations of stars by asteroids. When there are enough observations across the path of the shadow, the asteroid's projected…
Formation of asteroid pairs by rotational fission
P. Pravec, D. Vokrouhlicky, D. Polishook +23
Asteroid pairs sharing similar heliocentric orbits were found recently. Backward integrations of their orbits indicated that they separated gently with low relative velocities, but…
