The evolution of the flux-size relationship in protoplanetary discs by viscous evolution and radial pebble drift
Johan Appelgren, Anders Johansen, Michiel Lambrechts +4
In this paper we study the evolution of radiative fluxes, flux radii and observable dust masses in protoplanetary discs, in order to understand how these depend on the angular mome…

Formation of wide-orbit giant planets in protoplanetary disks with a decreasing pebble flux
Nerea Gurrutxaga, Anders Johansen, Michiel Lambrechts +1
The presence of distant protoplanets may explain the observed gaps in the dust emission of protoplanetary disks. Here, we derive a novel analytical model to describe the temporal d…

Dust clearing by radial drift in evolving protoplanetary discs
Johan Appelgren, Michiel Lambrechts, Anders Johansen
Recent surveys have revealed that protoplanetary discs typically have dust masses that appear to be insufficient to account for the high occurrence rate of exoplanet systems. We de…
