The triaxial ellipsoid dimensions, rotational pole, and bulk density of ESA Rosetta target asteroid (21) Lutetia
J. D. Drummond, A. Conrad, W. J. Merline +6
We seek the best size estimates of the asteroid (21) Lutetia, the direction of its spin axis, and its bulk density, assuming its shape is well described by a smooth featureless tri…
Shape modeling technique KOALA validated by ESA Rosetta at (21) Lutetia
B. Carry, M. Kaasalainen, W. J. Merline +12
We present a comparison of our results from ground-based observations of asteroid (21) Lutetia with imaging data acquired during the flyby of the asteroid by the ESA Rosetta missio…
Revealing Io's Surface using JWST-NIRISS Aperture Masking Interferometry and Neural Network Deconvolution
J. Sanchez-Bermudez, I. dePater, A. Conrad +6
Io is one of Jupiter's largest moons and the most volcanically active body in the Solar System. Its very active surface has hot spots produced by volcanic eruptions popping up at s…
Satellites of the largest Kuiper belt objects
M. E. Brown, M. A. van Dam, A. H. Bouchez +12
We have searched the four brightest objects in the Kuiper belt for the presence of satellites using the newly commissioned Keck Observatory Laser Guide Star Adaptive Optics system.…
Orbits of very distant asteroid satellites
K. Minker, B. Carry, F. Vachier +36
The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and…
Alignment and preliminary outcomes of an ELT-size instrument to a very large telescope: LINC-NIRVANA at LBT
M. Bergomi, L. Marafatto, V. Viotto +14
LINC-NIRVANA (LN) is a high resolution, near infrared imager that uses a multiple field-of-view, layer-oriented, multi-conjugate AO system, consisting of four multi-pyramid wavefro…
The homogeneous internal structure of CM-like asteroid (41) Daphne
B. Carry, F. Vachier, J. Berthier +48
Context. CM-like asteroids (Ch and Cgh classes) are a major population within the broader C-complex, encompassing about 10% of the mass of the main asteroid belt. Their internal st…
The Resolved Asteroid Program - Size, shape, and pole of (52) Europa
W. J. Merline, J. D. Drummond, B. Carry +14
With the adaptive optics (AO) system on the 10 m Keck-II telescope, we acquired a high quality set of 84 images at 14 epochs of asteroid (52) Europa on 2005 January 20. The epochs…
A dynamical dichotomy in large binary asteroids
K. Minker, B. Carry, F. Vachier +20
No less than 15% of large (diameter greater than 140 km) asteroids have satellites. The commonly accepted mechanism for their formation is post-impact reaccumulation. However, the…
Physical, spectral, and dynamical properties of asteroid (107) Camilla and its satellites
M. Pajuelo, B. Carry, F. Vachier +24
The population of large asteroids is thought to be primordial and they are the most direct witnesses of the early history of our Solar System. Those satellites allow study of the m…
Physical properties of ESA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry
B. Carry, M. Kaasalainen, C. Leyrat +22
Aims. We determine the physical properties (spin state and shape) of asteroid (21) Lutetia, target of the ESA Rosetta mission, to help in preparing for observations during the flyb…
