SUMMARY:From Protostars to Protoplanets: Towards a Population-level simula
 tion study of gravitationally unstable gas discs - Adam Koval (Edinburgh)

DESCRIPTION:Simulations of collapsing giant molecular clouds show protosta
 rs forming with discs that may be massive enough to become gravitationall
 y unstable. This may play a key role both in the formation of the star its
 elf\, and in the formation of giant planets through disc fragmentation. We
  extract a set of young discs (less than 1e5 years)  from a global cloud c
 ollapse simulation (Bate 2012). We upscale the resolution of these discs u
 sing a novel particle splitting method and employ an improved radiative co
 oling approximation in our runs - both as a requirement to accurately capt
 ure fragmenting planetary-mass clumps. This suite of physically-motivated 
 simulations from non-idealised initial conditions should provide a valuabl
 e insight into the frequency of disc fragmentation and any resultant proto
 planetary population. In this talk I will present the workflow and numeric
 al methods involved in this population study\, as well as some key insight
 s from early results
