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…
Disc population synthesis: Decrease in the solid mass reservoir through pebble drift
Johan Appelgren, Michiel Lambrechts, Nienke van der Marel
Surveys of star-forming regions reveal that the dust mass of protoplanetary discs decreases by several orders of magnitude on a timescale of a few million years. This decrease in t…
A potential site for wide-orbit giant planet formation in the IM Lup disk
Arthur Bosman, Johan Appelgren, Edwin A. Bergin +2
The radial transport, or drift, of dust has taken a critical role in giant planet formation theory. However, it has been challenging to identify dust drift pile ups in the hard-to-…
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…
