A massive primordial atmosphere on early Mars
Sarah Joiret, Alessandro Morbidelli, Rafael de Sousa Ribeiro +2
Mars finished forming while the solar nebula was still present, and acquired its primordial atmosphere from this reservoir. The absence of a detectable cometary xenon signature in…
Asteroids fail to retain cometary impact signatures
Sarah Joiret, Guillaume Avice, Ludovic Ferrière +4
A bombardment of comets is thought to have occurred in the inner solar system as a result of a dynamical instability among the giant planets after gas disk dispersal. Vesta, the se…
Crash Chronicles: relative contribution from comets and carbonaceous asteroids to Earth's volatile budget in the context of an Early Instability
Sarah Joiret, Sean N. Raymond, Guillaume Avice +1
Recent models of solar system formation suggest that a dynamical instability among the giant planets happened within the first 100 Myr after disk dispersal, perhaps before the Moon…
A race against the clock: Constraining the timing of cometary bombardment relative to Earth's growth
Sarah Joiret, Sean N. Raymond, Guillaume Avice +3
Comets are considered a potential source of inner solar system volatiles, but the timing of this delivery relative to that of Earth's accretion is still poorly understood. Measurem…
