Cometary surface dust layers built out of millimetre-scale aggregates: dependence of modelled cometary gas production on the layer transport properties

Yu. Skorov, J. Markkanen, V. Reshetnyk +5

The standard approach to obtaining knowledge about the properties of the surface layer of a comet from observations of gas production consists of two stages. First, various thermop…

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…

A Predicted Dearth of Majority Hypervolatile Ices in Oort Cloud Comets

C. M. Lisse, G. R. Gladstone, L. A. Young +30

We present new, ice species-specific New Horizons/Alice upper gas coma production limits from the 01 Jan 2019 MU69/Arrokoth flyby of Gladstone et al. (2021) and use them to make pr…

On the Origin and Thermal Stability of Arrokoths and Plutos Ices

C. M. Lisse, L. A. Young, D. P. Cruikshank +30

We discuss in a thermodynamic, geologically empirical way the long-term nature of the stable majority ices that could be present in Kuiper Belt Object 2014 MU69 after its 4.6 Gyr r…

Initial results from the New Horizons exploration of 2014 MU69, a small Kuiper Belt Object

S. A. Stern, H. A. Weaver, J. R. Spencer +202

The Kuiper Belt is a distant region of the Solar System. On 1 January 2019, the New Horizons spacecraft flew close to (486958) 2014 MU69, a Cold Classical Kuiper Belt Object, a cla…

The Geology and Geophysics of Kuiper Belt Object (486958) Arrokoth

J. R. Spencer, S. A. Stern, J. M. Moore +75

The Cold Classical Kuiper Belt, a class of small bodies in undisturbed orbits beyond Neptune, are primitive objects preserving information about Solar System formation. The New Hor…

Local manifestations of cometary activity

Jean-Baptiste Vincent, Tony Farnham, Ekkehard Kührt +5

Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, rep…

Tensile Strength of 67P/Churyumov-Gerasimenko Nucleus Material from Overhangs

N. Attree, O. Groussin, L. Jorda +52

We directly measure twenty overhanging cliffs on the surface of comet 67P/Churyumov-Gerasimenko extracted from the latest shape model and estimate the minimum tensile strengths nee…

The highly active Anhur-Bes regions in the 67P/Churyumov - Gerasimenko comet: results from OSIRIS/ROSETTA observations

S. Fornasier, C. Feller, J. C. Lee +51

The Southern hemisphere of the 67P/Churyumov-Gerasimenko comet has become visible from Rosetta only since March 2015. It was illuminated during the perihelion passage and therefore…

Modeling of the outburst on July 29th, 2015 observed with OSIRIS cameras in the southern hemisphere of comet 67P/Churyumov-Gerasimenko

A. Gicquel, M. Rose, J. -B. Vincent +60

Images of the nucleus and the coma (gas and dust) of comet 67P/Churyumov- Gerasimenko have been acquired by the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System)…

Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations

O. Groussin, L. Jorda, A. -T. Auger +49

We study the link between gravitational slopes and the surface morphology on the nucleus of comet 67P/Churyumov-Gerasimenko and provide constraints on the mechanical properties of…

Comet 67P/Churyumov-Gerasimenko: Constraints on its origin from OSIRIS observations

H. Rickman, S. Marchi, M. F. A'Hearn +12

One of the main aims of the ESA Rosetta mission is to study the origin of the solar system by exploring comet 67P/Churyumov-Gerasimenko at close range. In this paper we discuss the…
