Sequential Fragmentation of C/2025 K1 (ATLAS) After Its Near-Sun Passage
Dennis Bodewits, John W. Noonan, Michael S. P. Kelley +6
Comet C/2025 K1 (ATLAS) reached perihelion at 0.33 au on 2025 October 8. Daily monitoring by the LCO Outbursting Objects Key Project revealed a major activity increase between Nove…
Water vapor as a probe of the origin of gas in debris disks
Yasuhiro Hasegawa, Riouhei Nakatani, Isabel Rebollido +5
Debris disks embrace the formation and evolution histories of planetary systems. Recent detections of gas in these disks have received considerable attention, as its origin ties up…
Collisional heating of icy planetesimals. I. Catastrophic collisions
Björn J. R. Davidsson
Planetesimals in the primordial disc may have experienced a collisional cascade. If so, the comet nuclei later placed in the Kuiper belt, scattered disc, and Oort Cloud would prima…
Neutral gas coma dynamics: modeling of flows and attempts to link inner coma structures to properties of the nucleus
Raphael Marschall, Björn J. R. Davidsson, Martin Rubin +1
Deriving properties of cometary nuclei from coma data is of significant importance for our understanding of cometary activity and has implications beyond. Ground-based data represe…
Secondary gas in debris discs released following the decay of long-lived radioactive nuclides, catastrophic or resurfacing collisions
Amy Bonsor, Mark C. Wyatt, Sebastian Marino +3
Kuiper-like belts of planetesimals orbiting stars other than the Sun are most commonly detected from the thermal emission of small dust produced in collisions. Emission from gas, m…
CO2-driven surface changes in the Hapi region on Comet 67P/Churyumov-Gerasimenko
Björn J. R. Davidsson, F. Peter Schloerb, Sonia Fornasier +24
Between 2014 December 31 and 2015 March 17, the OSIRIS cameras on Rosetta documented the growth of a 140m wide and 0.5m deep depression in the Hapi region on Comet 67P/Churyumov-Ge…
