Investigation of Split Comet 240P/NEAT
David Jewitt, Jane Luu, Yoonyoung Kim
We present time-series observations of the split comet 240P/NEAT near perihelion, obtained using the Nordic Optical Telescope. The brighter component, 240P-A, has an estimated radi…
Nucleus and Postperihelion Activity of Interstellar Object 3I/ATLAS Observed by Hubble Space Telescope
Man-To Hui, David Jewitt, Max J. Mutchler +2
We report the detection of the nucleus of interstellar object 3I/ATLAS, using a nucleus extraction technique on Hubble Space Telescope (HST) observations taken between December 202…
Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS
David Jewitt, Man-To Hui, Max Mutchler +2
We present high angular resolution observations of the third known interstellar interloper, 3I/ATLAS, from the Hubble Space Telescope. The object is clearly active at 3.8 au pre-pe…
Down But Not Out: The Case of Long-Period Comet C/2021 O3 (Panstarrs)
David Jewitt. Jing Li, Michael Jaeger, Yoonyoung Kim
We combine ground- and space-based observations of long-period comet C/2021 O3 (Panstarrs) (perihelion distance 0.287 au) in order to investigate its reported near-perihelion destr…
Dust Emission and Dynamics
Jessica Agarwal, Yoonyoung Kim, Michael S. P. Kelley +1
When viewed from Earth, most of what we observe of a comet is dust. The influence of solar radiation pressure on the trajectories of dust particles depends on their cross-section t…
