Constraints on fifth forces and ultralight dark matter from OSIRIS-REx target asteroid Bennu
Yu-Dai Tsai, Davide Farnocchia, Marco Micheli +2
Using the OSIRIS-REx mission and ground-based tracking data for the asteroid Bennu, we derive new constraints on fifth forces and ultralight dark matter. The bounds we obtain are s…
Mining archival data from wide-field astronomical surveys in search of near-Earth objects
Teymoor Saifollahi, Gijs Verdoes Kleijn, Rees Williams +5
Increasing our knowledge of the orbits and compositions of Near-Earth Objects (NEOs) is important for a better understanding of the evolution of the Solar System and of life. The d…
Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei
Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9
We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
Asteroids seen by JWST-MIRI: Radiometric Size, Distance and Orbit Constraints
T. G. Müller, M. Micheli, T. Santana-Ros +3
Infrared measurements of asteroids are crucial for the determination of physical and thermal properties of individual objects, and for the understanding of the small-body populatio…
(523599) 2003 RM: The asteroid that wanted to be a comet
Davide Farnocchia, Darryl Z. Seligman, Mikael Granvik +11
We report a statistically significant detection of nongravitational acceleration on the sub-kilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences fa…
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…
