Prospects for detecting surface color heterogeneity on asteroid surfaces from sparse multiband photometric survey data
Oriel Humes, Jessica Agarwal
Automated sky surveys frequently report sparse-in-time multiband photometric observations of asteroids passing through their fields of view. Photometric data are currently availabl…
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…
Distribution and dynamics of decimeter-sized dust agglomerates in the coma of 67P/Churyumov-Gerasimenko
P. Lemos, J. Agarwal, M. Schröter
We present a method to analyze images of the coma of 67P/Churyumov-Gerasimenko obtained using OSIRIS, the main imaging system onboard \textit{Rosetta}, where dust aggregates can be…
Activity distribution of comet 67P/Churyumov-Gerasimenko from combined measurements of non-gravitational forces and torques
Nicholas Attree, Laurent Jorda, Olivier Groussin +5
Aims. Understanding the activity is vital for deciphering the structure, formation, and evolution of comets. We investigate models of cometary activity by comparing them to the dyn…
Disintegration of Long-Period Comet C/2021 A1 (Leonard)
David Jewitt, Yoonyoung Kim, Michael Mattiazzo +3
We present imaging observations of the disintegrating long-period comet C/2021 A1 (Leonard). High resolution observations with Hubble Space Telescope show no evidence for surviving…
Sublimation Origin of Active Asteroid P/2018 P3
Yoonyoung Kim, Jessica Agarwal, David Jewitt +4
Active asteroids show (typically transient) cometary activity, driven by a range of processes. A sub-set, sometimes called main-belt comets, may be driven by sublimation and so cou…
