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…
Adaptive optics and lightcurve data of asteroids: twenty shape models and information content analysis
Matti Viikinkoski, Josef Hanus, Mikko Kaasalainen +2
We present shape models and volume estimates of twenty asteroids based on relative photometry and adaptive optics images. We discuss error estimation and the effects of myopic deco…
Spin states of asteroids in the Eos collisional family
J. Hanuš, M. Delbo', V. Alí-Lagoa +33
Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. W…
Shape models of asteroids based on lightcurve observations with BlueEye600 robotic observatory
Josef Durech, Josef Hanus, Miroslav Broz +14
We present physical models, i.e. convex shapes, directions of the rotation axis, and sidereal rotation periods, of 18 asteroids out of which 10 are new models and 8 are refined mod…
Asteroid shapes and thermal properties from combined optical and mid-infrared photometry inversion
Josef Durech, Marco Delbo, Benoit Carry +2
Optical lightcurves can be used for the shape and spin reconstruction of asteroids. Due to unknown albedo, these models are scale-free. When thermal infrared data are available, th…
Shape and spin distributions of asteroid populations from brightness variation estimates and large databases
H. Nortunen, M. Kaasalainen, J. Ďurech +3
Context. Many databases on asteroid brightnesses (e.g. ALCDEF, WISE) are potential sources for extensive asteroid shape and spin modelling. Individual lightcurve inversion models r…
