Pedro Lacerda
One of the most fundamental problems in the study of Kuiper belt objects (KBOs) is to know their true physical size. Without knowledge of their albedos we are not able to distingui…
Prograde rotation of protoplanets by accretion of pebbles in a gaseous environment
Anders Johansen, Pedro Lacerda
We perform hydrodynamical simulations of the accretion of pebbles and rocks onto protoplanets of a few hundred kilometres in radius, including two-way drag force coupling between p…
