Towards a coupled activity-fallback model for comets I) 67P/Churyumov-Gerasimenko's water activity from a microphysics model with dynamic dust-depth
Nicholas Attree, Yuri Skorov, Pedro Gutiérrez +4
We apply a two-layer thermophysical model, with water sublimating from below a dust-crust with dynamically varying depth, to simulate the water outgassing rate, dust-ejections, and…
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…
Observations of the long-lasting activity of the distant Comets 29P Schwassmann-Wachmann 1, C/2003 WT42 (LINEAR) and C/2002 VQ94 (LINEAR)
Oleksandra Ivanova, Yury Skorov, Pavlo Korsun +2
We investigated three comets, which are active at large heliocentric distances, using observations obtained at the 6-m BTA telescope (SAO RAS, Russia) in the photometric mode of th…
The optical characteristics of the dust of sungrazing comet C/2012 S1 (ISON) observed at large heliocentric distances
Oleksandra Ivanova, Volodymyr Reshetnyk, Yury Skorov +7
We present an analysis of the photometric and spectroscopic data of the comet C/2012 S1 (ISON) observed at the heliocentric distances of 6.21÷4.81 AU. The photometric observations…
