Titan's Prolific Propane: The Cassini CIRS Perspective
C. A. Nixon, D. E. Jennings, J. -M. Flaud +7
In this paper we select large spectral averages of data from the Cassini Composite Infrared Spectrometer (CIRS) obtained in limb-viewing mode at low latitudes (30S--30N), greatly i…
Spitzer Observations of Spacecraft Target 162173 (1999 JU3)
H. Campins, J. P. Emery, M. Kelley +5
Near-Earth asteroid 162173 (1999 JU3) is the primary target of the Hayabusa-2 sample return mission, and a potential target of the Marco Polo sample return mission. Earth-based stu…
The dynamical role of the circumplanetary disc in planetary migration
A. Crida, C. Baruteau, W. Kley +1
Numerical simulations of planets embedded in protoplanetary gaseous discs are a precious tool for studying the planetary migration ; however, some approximations have to be made. M…
CoRoT-2a magnetic activity: hints for possible star-planet interaction
Isabella Pagano, Antonino F. Lanza, Giuseppe Leto +3
CoRoT-2a is a young (about 0.5 Gyr) G7V star accompanied by a transiting hot-Jupiter, discovered by the CoRoT satellite (Alonso et al. 2008; Bouchy et al. 2008). An analysis of its…
On the protection of extrasolar Earth-like planets around K/M stars against galactic cosmic rays
J. -M. Grießmeier, A. Stadelmann, J. L. Grenfell +2
Previous studies have shown that extrasolar Earth-like planets in close-in habitable zones around M-stars are weakly protected against galactic cosmic rays (GCRs), leading to a str…
Physical collisions of moonlets and clumps with the Saturn's F-ring core
Sebastien Charnoz
Since 2004, observations of Saturn's F ring have revealed that the ring's core is surrounded by structures with radial scales of hundreds of kilometers, called "spirals" and "jets"…
