Estimation of Yarkovsky acceleration using datamining in the perspective of Gaia
نویسنده
چکیده
The Yarkovsky effect is a weak non gravitational force that can modify the semi-major axis of asteroid. It has an important effect on the long term evolution of Near Earth Asteroids. The aim of this paper is to detect secular drift in the semi-major axis of some asteroids. The datamining can help to detect such a drift by extending the orbital arc. Finally the Yarkovsky effect is also considered in the Gaia mission context.

Detection of Yarkovsky acceleration in the context of precovery observations and the future Gaia catalogue
Context. The Yarkovsky effect is a weak non-gravitational force leading to a small variation of the semi-major axis of an asteroid. Using radar measurements and astrometric observations, it is possible to measure a drift in semi-major axis through orbit determination. Aims. This paper aims to detect a reliable drift in semi-major axis of near-Earth asteroids (NEAs) from ground-based observation...

متن کاملThe influence of global self-heating on the Yarkovsky and YORP effects
In addition to collisions and gravitational forces, there is a growing amount of evidence that photon recoil forces from the asymmetric reflection and thermal re-radiation of absorbed sunlight are primary mechanisms that are fundamental to the physical and dynamical evolution of small asteroids. The Yarkovsky effect causes orbital drift, and the YarkovskyO'Keefe-Radzievskii-Paddack (YORP) effec...
