Pebble accretion at the origin of Europa's water
T. Ronnet, O. Mousis & P. Vernazza 2017, ApJ.
Europa is one of the four massive Galilean satellites orbiting around Jupiter. A water ocean lies underneath its icy crust and is supposedly in contact with the rocky mantle below, making the satellite particularly interesting from an astrobiological point of view. This is due to the peculiar composition of Europa which contains approximately 8% of water by mass.
In this paper we investigated the possible origin of the water content of Europa. We propose that Europa could have formed just inside the water snowline from drifting pebbles whose water ice content has been partially sublimated.
Reconciling the orbital and physical properties of the Martian moons
T. Ronnet, P. Vernazza, O. Mousis, B. Brugger, P. Beck, B. Devouard, O. Witasse, F. Cipriani 2016, ApJ.
The origin of Phobos and Deimos, the two small moons orbiting about Mars, is a long standing puzzle. Their physical properties make them resemble small primitive asteroids that could have been gravitationally captured by Mars. However, their nearly circular and coplanar orbits are hardly reconcilable with a capture event.
Here we show that the formation of Phobos and Deimos following a giant impact on Mars allows to account for their spectral characteristics while it has been shown that it would also account for their orbital properties.
