Investigating Mercury's Environment with the Two-Spacecraft BepiColombo Mission
A. Milillo, M. Fujimoto, G. Murakami +76
The ESA-JAXA BepiColombo mission will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric dyna…
PG1018-047: the longest period subdwarf B binary
J. Deca, T. R. Marsh, R. H. Ãstensen +7
About 50% of all known hot subdwarf B stars (sdBs) reside in close (short period) binaries, for which common envelope ejection is the most likely formation mechanism. However, Han…
The source of electrons at comet 67P
P. Stephenson, A. Beth, J. Deca +8
We examine the origin of electrons in a weakly outgassing comet, using Rosetta mission data and a 3D collisional model of electrons at a comet. We have calculated a new dataset of…
Evolutionary Constraints on the Long-period Subdwarf B Binary PG 1018-047
J. Deca, J. Vos, P. Németh +4
We have revisited the sdB+K-star long-period binary PG 1018-047 based on 20 new high-resolution VLT/UVES spectra that provided regular coverage over a period of more than 26 months…
Solar wind dynamics around a comet - A 2D semi-analytical kinetic model
E. Behar, B. Tabone, M. Saillenfest +5
We aim at analytically modelling the solar wind proton trajectories during their interaction with a partially ionised cometary atmosphere, not in terms of bulk properties of the fl…
