The shape distribution of asteroid families -- evidence for evolution driven by small impacts
A statistical analysis of brightness variability of asteroids reveals how
their shapes evolve from elongated to rough spheroidal forms, presumably driven
by impact-related phenomena. Based on the Sloan Digital Sky Survey Moving
Object Catalog, we determined the shape distribution of 11,735 asteroids, with
special emphasis on eight prominent asteroid families. In young families,
asteroids have a wide range of shape elongations, implying
fragmentation-formation. In older families we see an increasing number of rough
spheroids, in agreement with the predictions of an impact-driven evolution. Old
families also contain a group of moderately elongated members, which we suggest
correspond to higher-density, more impact-resistant cores of former fragmented
asteroids that have undergone slow shape erosion. A few percent of asteroids
have very elongated shapes, and can either be young fragments or tidally
reshaped bodies. Our results confirm that the majority of asteroids are
gravitationally bound ``rubble piles''.Comment: Accepted by Icarus. 22 pages, 1 table, 6 figures, 31 figure panel
Large size and slow rotation of the trans-Neptunian object (225088) 2007 OR10 discovered from Herschel and K2 observations
We present the first comprehensive thermal and rotational analysis of the
second most distant trans-Neptunian object (225088) 2007 OR10. We combined
optical light curves provided by the Kepler space telescope -- K2 extended
mission and thermal infrared data provided by the Herschel Space Observatory.
We found that (225088) 2007 OR10 is likely to be larger and darker than derived
by earlier studies: we obtained a diameter of d=1535^{+75}_{-225} km which
places (225088) 2007 OR10 in the biggest top three trans-Neptunian objects. The
corresponding visual geometric albedo is p_V=0.089^{+0.031}_{-0.009}. The light
curve analysis revealed a slow rotation rate of P_rot=44.81+/-0.37 h,
superseded by a very few objects only. The most likely light-curve solution is
double-peaked with a slight asymmetry, however, we cannot safely rule out the
possibility of having a rotation period of P_rot=22.40+/-0.18 h which
corresponds to a single-peaked solution. Due to the size and slow rotation, the
shape of the object should be a MacLaurin ellipsoid, so the light variation
should be caused by surface inhomogeneities. Its newly derived larger diameter
also implies larger surface gravity and a more likely retention of volatiles --
CH_4, CO and N_2 -- on the surface.Comment: Accepted for publication in AJ, 8 pages in emulateapj styl
