The diverse lives of young protoplanets in self-gravitating discs

Stars are born with discs that during their initial stages of formation are relatively 
massive, asymmetric and they are being fed with material from their parent clouds. 
ALMA observations have revealed young discs with multiple gaps and discs with 
spiral structures. Such features may be due to forming planets, raising the exciting 
possibility that planets and planetary systems may form much faster than it has been 
previously thought. I will discuss whether gravitational instabilities may be 
responsible for the fast formation of proto-planets in early-phase protostellar 
discs. I will also discuss how young proto-planets evolve when they form within 
relatively massive discs, and I will argue that their fate is quite diverse, 
depending on the detailed physics of their interactions with their parent discs.
