A recent disruption of the main-belt asteroid P/2010 A2
TLDR
Observations of P/2010 A2, a previously unknown inner-belt asteroid with a peculiar, comet-like morphology, are reported, concluding that it is most probably the remnant of a recent asteroidal disruption in February/March 2009, evolving slowly under the action of solar radiation pressure.
Tumbling motion of 1I/‘Oumuamua and its implications for the body’s distant past
Models of the Solar System’s evolution show that almost all the primitive material leftover from the formation of the planets was ejected to the interstellar space as a result of dynamical
The Excited Spin State of 1I/2017 U1 `Oumuamua
We show that `Oumuamua's excited spin could be in a high energy LAM state, which implies that its shape could be far from the highly elongated shape found in previous studies. CLEAN and ANOVA
THE SOURCES OF HCN AND CH3OH AND THE ROTATIONAL TEMPERATURE IN COMET 103P/HARTLEY 2 FROM TIME-RESOLVED MILLIMETER SPECTROSCOPY*
One of the least understood properties of comets is the compositional structure of their nuclei, which can either be homogeneous or heterogeneous. The nucleus structure can be conveniently studied at
Comet 67P/Churyumov-Gerasimenko at a large heliocentric distance
Aims. The Jupiter family comet 67P/Churyumov-Gerasimenko (67P/C-G) is the target comet of ESA's ROSETTA mission. A detailed portrait of this comet has been drawn from observations around perihelion,
Initial characterization of interstellar comet 2I/Borisov
Interstellar comets penetrating through the Solar System had been anticipated for decades 1 , 2 . The discovery of asteroidal-looking ‘Oumuamua 3 , 4 was thus a huge surprise and a puzzle.
FAST ROTATION AND TRAILING FRAGMENTS OF THE ACTIVE ASTEROID P/2012 F5 (GIBBS)*
While having a comet-like appearance, P/2012 F5 (Gibbs) has an orbit native to the Main Asteroid Belt, and physically is a km-sized asteroid which recently (mid 2011) experienced an impulsive mass
Rotation-stimulated structures in the CN and C3 comae of comet 103P/Hartley 2 close to the EPOXI encounter
In late 2010 a Jupiter Family comet 103P/Hartley 2 was a subject of an intensive world-wide investigation. On UT October 20.7 the comet approached the Earth within only 0.12 AU, and on UT November
Tumbling motion of 1I/'Oumuamua reveals body's violent past
Models of the Solar System evolution show that almost all the primitive material leftover from the formation of the planets was ejected to the interstellar space as a result of dynamical
