How primordial is the structure of comet 67P/C-G? Combined collisional and dynamical models suggest a late formation
M. Jutzi, W. Benz, A. Toliou +2
There is an active debate about whether the properties of comets as observed today are primordial or, alternatively, if they are a result of collisional evolution or other processe…
Challenges in Planet Formation
Alessandro Morbidelli, Sean N. Raymond
Over the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundam…
Evolution of Protoplanetary Discs with Magnetically Driven Disc Winds
Takeru K. Suzuki, Masahiro Ogihara, Alessandro Morbidelli +2
Aims: We investigate the evolution of protoplanetary discs (PPDs hereafter) with magnetically driven disc winds and viscous heating. Methods: We consider an initially massive disc…
Yarkovsky V-shape identification of asteroid families
Bryce T. Bolin, Marco Delbo, Alessandro Morbidelli +1
There are only a few known main belt (MB) asteroid families with ages greater than 2 Gyr (Brož et al. 2013, Spoto et al. 2015). Estimates based on the family producing collision ra…
The Asteroid Belt as a Relic From a Chaotic Early Solar System
Andre Izidoro, Sean N. Raymond, Arnaud Pierens +3
The orbital structure of the asteroid belt holds a record of the Solar System's dynamical history. The current belt only contains Earth masses yet the asteroid…
Highly siderophile elements were stripped from Earth's mantle by iron sulfide segregation
David C. Rubie, Vera Laurenz, Seth A. Jacobson +4
Highly siderophile elements (HSEs) are strongly depleted in the bulk silicate Earth (BSE) but are present in near-chondritic relative abundances. The conventional explanation is th…
