Dynamical tomography of gravitationally bound systems
Mikko Kaasalainen
We study the inverse problem of deducing the dynamical characteristics (such as the potential field) of large systems from kinematic observations. We show that, for a class of stea…
The complementarity of astrometric and radial velocity exoplanet observations - Determining exoplanet mass with astrometric snapshots
M. Tuomi, S. Kotiranta, M. Kaasalainen
We obtain full information on the orbital parameters by combining radial velocity and astrometric measurements by means of Bayesian inference. We sample the parameter probability d…
Main Belt Binary Asteroidal Systems With Circular Mutual Orbits
F. Marchis, P. Descamps, M. Baek +5
In 2003, we initiated a long-term adaptive optics campaign to study the orbit of various main-belt asteroidal systems. Here we present a consistent solution for the mutual orbits o…
New determination of the size and bulk density of the binary asteroid 22 Kalliope from observations of mutual eclipses
P. Descamps, F. Marchis, J. Pollock +16
In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual equinoxes. As a consequence, the orbit plane of its small moon, Linus, was aligned closely to the Sun's li…
Thermal infrared observations of the Hayabusa spacecraft target asteroid 25143 Itokawa
T. G. Mueller, T. Sekiguchi, M. Kaasalainen
We obtained N- and Q-band observations of the Apollo-type asteroid 25143 Itokawa during its close Earth approach in July 2004 with TIMMI2 at the ESO 3.6 m telescope. Our photometri…
