The role of planetesimal fragmentation on giant planet formation
(Edp Sciences, 2014-01)
Context. In the standard scenario of planet formation, terrestrial planets and the cores of the giant planets are formed by accretion of planetesimals. As planetary embryos grow, the planetesimal velocity dispersion increases ...
Impact disruption of primordial planetesimals
(Pergamon-elsevier Science Ltd, 2013-01)
It isusually assumed that 1-10-km sized planetesimals are formed through coagulation processes and continue to agglomerate via pairwise mergers. However, recent models of planetesimal formation suggest that ...
Planetesimal fragmentation and giant planet formation
(EDP Sciences, 2019-05)
Context. Most planet formation models that incorporate planetesimal fragmentation consider a catastrophic impact energy threshold for basalts at a constant velocity of 3 km/s throughout the process of the formation of the ...
On oligarchic growth of planets in protoplanetary disks
(Academic Press Inc Elsevier Science, 2008-01)
In this paper we present a new semianalytical model of oligarchic growth of planets considering a distribution of planetesimal sizes, fragmentation of planetesimals in mutual collisions, sublimation of ices through the ...
The effects of ablation on the cross section of planetary envelopes at capturing planetesimals
(Academic Press Inc Elsevier Science, 2008-02)
We explore the cross section of giant planet envelopes at capturing planetesimals of different sizes. For this purpose we employ two sets of realistic planetary envelope models (computed assuming for the protoplanetary ...
The characterization of the dust content in the ring around Sz 91: indications of planetesimal formation?
(IOP, 2021)
One of the most important questions in the field of planet formation is how millimeter- and centimeter-sized dust
particles overcome radial drift and fragmentation barriers to form kilometer-sized planetesimals. ...
