A metallicity sweet spot for disc fragmentation and planet formation
Ethan J. Carter, Dimitris Stamatellos, George Blaylock-Squibbs +2
Fragmentation of gravitationally unstable discs offers an alternate formation mechanism for gas giant planets and brown dwarfs on wide orbits. Metallicity plays a key role in disc…
Revisiting gravitational instability in protostellar discs with improved radiative cooling models
Alison K. Young, Ken Rice, Richard Booth +1
Young discs are expected to be significantly more massive than those observed at Myr and it is at this earliest stage that planet formation likely begins. Such massive discs m…
On the Gravitational Collapse of Small Dust Grains in Self-gravitating Disk Structures
Hans Baehr, Ken Rice, Chao-Chin Yang +1
Planet formation may begin much earlier than previously expected, when the protoplanetary disk is still massive and gravitationally unstable. It has been proposed that solid grains…
Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs
Ken Rice, Hans Baehr, Alison K Young +5
Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…
