Dark Comets? Unexpectedly Large Nongravitational Accelerations on a Sample of Small Asteroids
Darryl Z. Seligman, Davide Farnocchia, Marco Micheli +15
We report statistically significant detections of non-radial nongravitational accelerations based on astrometric data in the photometrically inactive objects 1998 KY, 2005 V…
Polarimetric Properties of the Near--Sun Asteroid (155140) 2005 UD in Comparison with Other Asteroids and Meteoritic Samples
Masateru Ishiguro, Yoonsoo P. Bach, Jooyeon Geem +26
The investigation of asteroids near the Sun is important for understanding the final evolutionary stage of primitive solar system objects. A near-Sun asteroid, (155140) 2005 UD, ha…
(6478) Gault: Physical characterization of an active main-belt asteroid
Maxime Devogèle, Marin Ferrais, Emmanuel Jehin +22
In December 2018, the main-belt asteroid (6478)~Gault was reported to display activity. Gault is an asteroid belonging to the Phocaea dynamical family and was not previously known…
Establishing Earth's Minimoon Population through Characterization of Asteroid 2020 CD
Grigori Fedorets, Marco Micheli, Robert Jedicke +20
We report on our detailed characterization of Earth's second known temporary natural satellite, or minimoon, asteroid 2020 CD3. An artificial origin can be ruled out based on its a…
Composition and origin of L5 Trojan asteroids of Mars: Insights from spectroscopy
Apostolos A. Christou, Galin Borisov, Aldo Dell'Oro +2
We investigate the mineralogy of L5 Martian Trojan asteroids via reflectance spectroscopy, in particular (101429) 1998 $\mbox{VF}_{31}$, the only L5 Trojan that does not belong to…
Visible spectroscopy from the Mission Accessible Near-Earth Object Survey (MANOS): Taxonomic dependence on asteroid size
Maxime Devogele, Nicholas Moskovitz, Audrey Thirouin +14
The Mission Accessible Near-Earth Object Survey (MANOS) aims to observe and characterize small (mean absolute magnitude H ~ 25 mag) Near-Earth Objects (NEOs) that are accessible by…
A common origin for dynamically associated near-Earth asteroid pairs
Nicholas Moskovitz, Petr Fatka, Davide Farnocchia +19
Though pairs of dynamically associated asteroids in the Main Belt have been identified and studied for over a decade, very few pair systems have been identified in the near-Earth a…
Dust Properties of Double-Tailed Active Asteroid (6478) Gault
F. Moreno, E. Jehin, J. Licandro +11
Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active asteroid population in the main…
Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016
E. Meza, B. Sicardy, M. Assafin +167
Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…
New Jupiter Satellites and Moon-Moon Collisions
Scott Sheppard, Gareth Williams, David Tholen +7
We report the discovery of 12 new satellites of Jupiter, giving Jupiter 79 known satellites. The new finds are between 23rd-24th mag in the r-band and 1-3 km in diameter assuming d…
Rotational variation of the linear polarisation of the asteroid (3200) Phaethon as evidence for inhomogeneity in its surface properties
G. Borisov, M. Devogèle, A. Cellino +23
Asteroid (3200) Phaethon is a Near-Earth Apollo asteroid with an unusual orbit that brings it closer to the Sun than any other known asteroid. Its last close approach to the Earth…
The phase-polarization curve of asteroid (3200) Phaethon
M. Devogèle, A. Cellino, G. Borisov +10
A multi-colour phase-polarization curve of asteroid (3200)~Phaethon has been obtained during the December 2017 apparition by merging measurements taken at the observing station of…
New polarimetric and spectroscopic evidence of anomalous enrichment in spinel-bearing Calcium-Aluminium-rich Inclusions among L-type asteroids
M. Devogèle, P. Tanga, A. Cellino +14
Asteroids can be classified into several groups based on their spectral reflectance. Among these groups, the one belonging to the L-class in the taxonomic classification based on v…
Shape and spin determination of Barbarian asteroids
M. Devogèle, P. Tanga, P. Bendjoya +51
Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are named after (234) Barb…
Near-Earth asteroid (3200) Phaethon. Characterization of its orbit, spin state, and thermophysical parameters
J. Hanus, M. Delbo, D. Vokrouhlicky +15
The near-Earth asteroid (3200) Phaethon is an intriguing object: its perihelion is at only 0.14 au and is associated with the Geminid meteor stream. We aim to use all available dis…
The non-convex shape of (234) Barbara, the first Barbarian
P. Tanga, B. Carry, F. Colas +37
Asteroid (234) Barbara is the prototype of a category of asteroids that has been shown to be extremely rich in refractory inclusions, the oldest material ever found in the Solar Sy…
