Dumb-bell-shaped equilibrium figures for fiducial contact-binary asteroids and EKBOs
Pascal Descamps
In this work, we investigate the equilibrium figures of a dumb-bell-shaped sequence with which we are still not well acquainted. Studies have shown that these elongated and nonconv…
Triplicity and Physical Characteristics of Asteroid (216) Kleopatra
Pascal Descamps, F. Marchis, J. Berthier +16
To take full advantage of the September 2008 opposition passage of the M-type asteroid (216) Kleopatra, we have used near-infrared adaptive optics (AO) imaging with the W.M. Keck I…
Angular Momemtum of Binary Asteroids: Implication for their possible origin
Pascal Descamps, Franck Marchis
We describe in this work a thorough study of the physical and orbital characteristics of extensively observed main-belt and Trojan binaries, mainly taken from the LAOSA (Large Adap…
A spectral comparison of (379) Huenna and its satellite
Francesca DeMeo, Benoit Carry, Franck Marchis +7
We present near-infrared spectral measurements of Themis family asteroid (379) Huenna (D~98 km) and its 6 km satellite using SpeX on the NASA IRTF. The companion was farther than 1…
A low density of 0.8 g/cc for the Trojan binary asteroid 617 Patroclus
Franck Marchis, Daniel Hestroffer, Pascal Descamps +15
The Trojan population consists of two swarms of asteroids following the same orbit as Jupiter and located at the L4 and L5 Lagrange points of the Jupiter-Sun system (leading and fo…
