Cometary Activity Begins at Kuiper Belt Distances: Evidence from C/2017 K2
David Jewitt, Yoonyoung Kim, Max Mutchler +3
We study the development of activity in the incoming long-period comet C/2017 K2 over the heliocentric distance range 9 < r_H < 16 AU. The comet continues to be characterized by a…
Outbursting Quasi-Hilda Asteroid P/2010 H2 (Vales)
David Jewitt, Yoonyoung Kim
Quasi-Hilda asteroid P/2010 H2 (Vales) underwent a spectacular photometric outburst by 7.5 magnitudes (factor of 1000) in 2010. Here, we present our optical observations of this ev…
Component properties and mutual orbit of binary main-belt comet 288P/(300163) 2006 VW139
Jessica Agarwal, Yoonyoung Kim, David Jewitt +3
The binary asteroid 288P/(300163) is unusual both for its combination of wide-separation and high mass ratio and for its comet-like activity. It is not currently known whether ther…
Outburst and Splitting of Interstellar Comet 2I/Borisov
David Jewitt, Yoonyoung Kim, Max Mutchler +3
We present Hubble Space Telescope observations of a photometric outburst and splitting event in interstellar comet 2I/Borisov. The outburst, first reported with the comet outbound…
Coma Anisotropy and the Rotation Pole of Interstellar Comet 2I/Borisov
Yoonyoung Kim, David Jewitt, Max Mutchler +3
Hubble Space Telescope observations of interstellar comet 2I/Borisov near perihelion show the ejection of large (>~100 um) particles at <~9 m/s speeds, with estimated mass-loss rat…
The Nucleus of Interstellar Comet 2I/Borisov
David Jewitt, Man-To Hui, Yoonyoung Kim +3
We present high resolution imaging observations of interstellar comet 2I/Borisov (formerly C/2019 Q4) obtained using the Hubble Space Telescope. Scattering from the comet is domina…
