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…
Observations of Disintegrating Long-Period Comet C/2019 Y4 (ATLAS) -- A Sibling of C/1844 Y1 (Great Comet)
Man-To Hui, Quan-Zhi Ye
We present a study of C/2019 Y4 (ATLAS) using Sloan observations from mid-January to early April 2020. During this timespan, the comet brightened with a growth in the effecti…
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…
Asteroid (3200) Phaethon: colors, phase curve, limits on cometary activity and fragmentation
Maryam Tabeshian, Paul Wiegert, Quanzhi Ye +3
We report on a multi-observatory campaign to examine asteroid 3200 Phaethon during its December 2017 close approach to Earth, in order to improve our measurements of its fundamenta…
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…
