    • Are the observed gaps in protoplanetary discs caused by growing planets? 

      Ndugu, N.; Bitsch, B.; . Jurua, E (Oxford University Press on behalf of the Royal Astronomical Society, 2019-06-25)
      ABSTRACT Recent detailed observations of protoplanetary discs revealed a lot of substructures that are mostly ring like. One interpretation is that these rings are caused by growing planets. These potential planets are ...

    • Planet population synthesis driven by pebble accretion in cluster environments 

      Ndugu, N.; Bitsch, B.; Jurua, E. (Oxford University Press on behalf of the Royal Astronomical Society, 2016-12)
      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 stellar surface density destroy protoplanetary ...

    • Probing the impact of varied migration and gas accretion rates for the formation of giant planets in the pebble accretion scenario 

      Ndugu, N; Bitsch, B; Morbidelli, A; Crida, A; Jurua, E (Monthly Notices of the Royal Astronomical Society, 2020)
      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, while more massive planets migrate in ...

    • The Structure of a Quasi-Keplerian Accretion Disk around Magnetized Stars 

      Habumugisha, Isaac; Jurua, Edward; Tessema, Solomon B.; Simon, Anguma K. (The Astrophysical Journal, 2018-06)
      In this paper, we present the complete structure of a quasi-Keplerian thin accretion disk with an internal dynamo around a magnetized neutron star. We assume a full quasi-Keplerian disk with the azimuthal velocity deviating ...
