New research indicates that gas giant formation could have a surprising twist: Those planets might start off much flatter.
Flat Earth? More like flat Jupiter. New research suggests that gas giants like Jupiter may actually start off much flatter during their formation phase. A new paper featured in Astronomy and Astrophysics Letters details the findings, including highlighting how the researchers came to their conclusions. The most widely accepted theory for planetary formation is the theory of 'core accretion.
Many of these protoplanets are surprisingly flatter than would be expected based on core accretion. However, the researchers say that it is likely they will eventually evolve into gas giants as we know them, with more spherical appearances. But for now, they are twice as flat as Saturn, which has raised some questions. With the theory of disc instability, the formation of gas giants into flat and then more rounded planets makes more sense.
