Fitting the Light Curve of 1I/`Oumuamua with a Nonprincipal Axis Rotational Model and Outgassing Torques
Aster G. Taylor, Darryl Z. Seligman, Olivier R. Hainaut +1
In this paper, we investigate the nonprincipal axis (NPA) rotational state of 1I/`Oumuamua -- the first interstellar object discovered traversing the inner Solar System -- from its…
Analysis of the possible satellite contamination in LAMOST-MRS spectra
Mikhail Kovalev, Olivier R. Hainaut, Xuefei Chen +1
We present the detection of false positive double-lined spectroscopic binaries candidates (SB2) using medium-resolution survey (MRS) spectra from the one time-domain field of LAMOS…
(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…
