It is well known that giant planets open deep gaps in their natal gaseous protoplanetary discs. However, it is unclear how gas accretion onto growing planets influences the shape and depth of their growing gaps. We perform isothermal hydrodynamical simulations with the Fargo-2D1D code in which planets accrete gas within full discs that range...

The terrestrial planets and the asteroids dominant in the inner asteroid belt are water poor. However, in the protoplan-etary disk the temperature should have decreased below water-condensation level well before the disk was photo-evaporated. Thus, the global water depletion of the inner Solar System is puzzling. We show that, even if the inner...

Context. The discovery of planets orbiting at less than 1 au from their host star and less massive than Saturn in various exoplanetary systems revolutionized our theories of planetary formation. The fundamental question is whether these close-in low-mass planets could have formed in the inner disk interior to 1 au, or whether they formed...
