Temperature is the key to showing how gas giants form say researchers
... that one particular feature could be used to distinguish between the two theories - temperature. For the case of core accretion, the circumplanetary disk was heated to several hundreds of Kelvins whereas for the disk instability scenario, the...

How to Build Planets
... they are not lost to the disc through rapid migration,” explains Gonzalez. Accordingly, the long-standing core accretion timescale conflict is overcome in these simulations. An artist’s impression showing how the planet inside the disc of Beta...

Protoplanetary disc shares similarities with our own Solar System say researchers
...that in turn decreases the time scale for giant planet core accretion. DIGIT stands for Dust, Ice, and Gas In Time... Another possibility is the crystallisation of ice through extreme accretion events freeing enough energy to heat up and crystallise the...

New research challenges ideas on how the Earth was made
... widely accepted that after the Earth formed via a process known as core accretion (whereby proto-planetary bodies grow to massive sizes through the accretion of material from the proto-planetary disc), it underwent a process known as differentiation...

Super-Jupiter mass planet found in the galactic bulge
... difficult and unpredictable. Finding such a massive planet orbiting a cool dwarf star is also predicted to be rare by the core accretion theory of planet formation, but as light from the event was also covered by the Wise Observatory, the...
