Physical and dynamical properties of selected Earth co-orbital asteroids
Galin B. Borisov, Apostolos A. Christou, Gordana Apostolovska
We present our investigations of the physical and dynamical properties of selected Earth co-orbital asteroids. The photometric optical light curves as well as rotation periods and…
(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…
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…
Polarimetric analysis of STEREO observations of sungrazing Kreutz comet C/2010 E6 (STEREO)
Rok Nežič, Stefano Bagnulo, Geraint H. Jones +2
Twin STEREO spacecraft pre-perihelion photometric and polarimetric observations of the sungrazing Kreutz comet C/2010 E6 (STEREO) in March 2010 at heliocentric distances $3-28~R_{\…
Population control of Mars Trojans by the Yarkovsky & YORP effects
Apostolos A. Christou, Galin Borisov, Aldo Dell'Oro +3
We explore the hypothesis that the population of Martian Trojans is the result of a balance between the production of new asteroids ("YORPlets") through the YORP effect and their e…
(121514) 1999 UJ7: A primitive, slow-rotating Martian Trojan
G. Borisov, A. A. Christou, F. Colas +3
Aims. The goal of this investigation is to determine the origin and surface composition of the asteroid (121514) 1999 UJ7, the only currently known L4 Martian Trojan asteroid. Meth…
