Thermophysical model for icy cometary dust particles
Johannes Markkanen, Jessica Agarwal
Context. Cometary dust particles are subjected to various forces after being lifted off the nucleus. These forces define the dynamics of dust, trajectories, alignment, and fragment…
The dust-to-gas ratio, size distribution, and dust fall-back fraction of comet 67P/Churyumov-Gerasimenko: Inferences from linking the optical and dynamical properties of the inner comae
Raphael Marschall, Johannes Markkanen, Selina-Barbara Gerig +3
In this work, we present results that simultaneously constrain the dust size distribution, dust-to-gas ratio, fraction of dust re-deposition, and total mass production rates for co…
Scattering, absorption, and thermal emission by large cometary dust particles: Synoptic numerical solution
Johannes Markkanen, Jessica Agarwal
Context: Remote light scattering and thermal infrared observations provide clues about the physical properties of cometary and interplanetary dust particles. Identifying these prop…
