Effect of nucleation on icy pebble growth in protoplanetary discs
Katrin Ros, Anders Johansen, Ilona Riipinen +1
Solid particles in protoplanetary discs can grow by direct vapour deposition outside of ice lines. The presence of microscopic silicate particles may nevertheless hinder growth int…
(16) Psyche: A mesosiderite-like asteroid?
M. Viikinkoski, P. Vernazza, J. Hanus +35
Asteroid (16) Psyche is the target of the NASA Psyche mission. It is considered one of the few main-belt bodies that could be an exposed proto-planetary metallic core and that woul…
DISCUS - The Deep Interior Scanning CubeSat mission to a rubble pile near-Earth asteroid
Patrick Bambach, Jakob Deller, Esa Vilenius +5
We have performed an initial stage conceptual design study for the Deep Interior Scanning CubeSat (DISCUS), a tandem 6U CubeSat carrying a bistatic radar as main payload. DISCUS wi…
Distribution of shape elongations of main belt asteroids derived from Pan-STARRS1 photometry
H. Cibulková, H. Nortunen, J. Ďurech +10
Context. A lot of photometric data is produced by surveys such as Pan-STARRS, LONEOS, WISE or Catalina. These data are a rich source of information about the physical properties of…
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…
Volumes and bulk densities of forty asteroids from ADAM shape modeling
Josef Hanus, Matti Viikinkoski, Franck Marchis +11
Disk-integrated photometric data of asteroids do not contain accurate information on shape details or size scale. Additional data such as disk-resolved images or stellar occultatio…
Asteroid Models from Multiple Data Sources
J. Durech, B. Carry, M. Delbo +2
In the past decade, hundreds of asteroid shape models have been derived using the lightcurve inversion method. At the same time, a new framework of 3-D shape modeling based on the…
The Puzzling Mutual Orbit of the Binary Trojan Asteroid (624) Hektor
F. Marchis, J. Durech, J. Castillo-Rogez +9
Asteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan as…
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…
Analysis of the rotation period of asteroids (1865) Cerberus, (2100) Ra-Shalom, and (3103) Eger - search for the YORP effect
J. Durech, D. Vokrouhlicky, A. R. Baransky +28
The spin state of small asteroids can change on a long timescale by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropically scatter…
Optimal computation of brightness integrals parametrized on the unit sphere
Mikko Kaasalainen, Xiaoping Lu, Anssi-Ville Vänttinen
We compare various approaches to find the most efficient method for the practical computation of the lightcurves (integrated brightnesses) of irregularly shaped bodies such as aste…
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…
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…
