Distant Comet C/2017 K2 and the Cohesion Bottleneck
David Jewitt, Jessica Agarwal, Man-To Hui +3
Distant long-period comet C/2017 K2 has been outside the planetary region of the solar system for 3 Myr, negating the possibility that heat retained from the previous perihelion co…
Interpretation of the phase functions measured by the OSIRIS instrument for Comet 67P/Churyumov-Gerasimenko
Johannes Markkanen, Jessica Agarwal, Timo Väisänen +2
We show that the scattering phase functions of the coma and the nucleus of the comet 67P/Churyumov-Gerasimenko measured by the Rosetta/OSIRIS instrument can be reproduced by a part…
Hubble Space Telescope Observations of 3200 Phaethon At Closest Approach
David Jewitt, Max Mutchler, Jessica Agarwal +1
We present Hubble Space Telescope observations of the active asteroid (and Geminid stream parent) 3200 Phaethon when at its closest approach to Earth (separation 0.07 AU) in 2017 D…
Linking surface morphology, composition, and activity on the nucleus of 67P/Churyumov-Gerasimenko
S. Fornasier, V. H. Hoang, P. H. Hasselmann +37
The Rosetta space probe accompanied comet 67P/Churyumov-Gerasimenko for more than two years, obtaining an unprecedented amount of unique data of the comet nucleus and inner coma. T…
Nucleus of active asteroid 358P/Pan-STARRS (P/2012 T1)
Jessica Agarwal, Michael Mommert
The dust emission from active asteroids is likely driven by collisions, fast rotation, sublimation of embedded ice, and combinations of these. Characterising these processes leads…
The Nucleus of Active Asteroid 311P/(2013 P5) PANSTARRS
David Jewitt, Harold Weaver, Max Mutchler +3
The unique inner-belt asteroid 311P/PANSTARRS (formerly P/2013 P5) is notable for its sporadic, comet-like ejection of dust in nine distinct epochs spread over 250 days in 20…
