Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…

Observational constraints to the dynamics of dust particles in the coma of comet 67P/Churyumov-Gerasimenko
Elisa Frattin, I. Bertini, S. L. Ivanovski +18
In this work we aim to characterise the dust motion in the inner coma of comet 67P/Churyumov- Gerasimenko to provide constraints for theoretical 3D coma models. The OSIRIS camera o…
Activity of the Jupiter co-orbital comet P/2019~LD (ATLAS) observed with OSIRIS at the 10.4 m GTC
J. Licandro, J. de Leon, F. Moreno +8
Jupiter co-orbital comets have orbits that are not long-term stable. They may experience flybys with Jupiter close enough to trigger tidal disruptions like the one suffered by come…

In this work, we present the results of an observational study of 2I/Borisov carried out with the 10.4-m Gran Telescopio Canarias (GTC) and the 3.6-m Telescopio Nazionale Galileo (…
Dust Properties of Double-Tailed Active Asteroid (6478) Gault
F. Moreno, E. Jehin, J. Licandro +11
Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active asteroid population in the main…
Synthesis of the Morphological Description of Cometary Dust at Comet 67P
C. Güttler, T. Mannel, A. Rotundi +28
Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust, supported by plentiful data from Earth based observations and interplanetary dust particles…
Disrupted asteroid P/2016 G1. II. Follow-up observations from the Hubble Space Telescope
F. Moreno, J. Licandro, M. Mutchler +3
After the early observations of the disrupted asteroid P/2016 G1 with the 10.4m Gran Telescopio Canarias (GTC), and the modeling of the dust ejecta, we have performed a follow-up o…
The Castalia Mission to Main Belt Comet 133P/Elst-Pizarro
C. Snodgrass, G. H. Jones, H. Boehnhardt +41
We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently icy bodies within th…
