How external photo-evaporation changes the chemical composition of the inner disc
Nelson Ndugu, Bertram Bitsch, Julia Lena Lienert
Stars mostly form in clusters where neighboring stars can influence proto-planetary disc evolution. Besides gravitational interactions, external photoevaporation can shape these di…
The role of density perturbation on planet formation by pebble accretion
Geoffrey Andama, Nelson Ndugu, Simon . K. Anguma +1
Protoplanetary discs exhibit a diversity of gaps and rings of dust material, believed to be a manifestation of pressure maxima commonly associated with an ongoing planet formation…
Planet population synthesis: The role of stellar encounters
Nelson Ndugu, Oyirwoth Patrick Abedigamba, Geoffrey Andama
Depending on the stellar densities, protoplanetary discs in stellar clusters undergo background heating, disc truncation-driven by stellar encounter, and photo-evaporation. Disc tr…
Planetary core formation via multi-species pebble accretion
Geoffrey Andama, Nelson Ndugu, Simon Katrini Anguma +1
In the general classical picture of pebble-based core growth, planetary cores grow by accretion of single pebble species. The growing planet may reach the so-called pebble isolatio…
Probing the impact of varied migration and gas accretion rates for the formation of giant planets in the pebble accretion scenario
Nelson Ndugu, Bertram Bitsch, Alessandro Morbidelli +2
The final orbital position of growing planets is determined by their migration speed, which is essentially set by the planetary mass. Small mass planets migrate in type I migration…
Are the observed gaps in protoplanetary discs caused by growing planets?
Nelson Ndugu, Bertram Bitsch, Edward Jurua
Recent detailed observations of protoplanetary discs revealed a lot of sub-structures which are mostly ring-like. One interpretation is that these rings are caused by growing plane…
Planet population synthesis driven by pebble accretion in cluster environments
Nelson Ndugu, Bertram Bitsch, Edward Jurua
The evolution of protoplanetary discs embedded in stellar clusters depends on the age and the stellar density in which they are embedded. Stellar clusters of young age and high ste…
