    • Planet population synthesis: The role of stellar encounters 

      Ndugu, Nelson; Oyirwoth, Patrick Abedigamba; Andama, Geoffrey (Royal Astronomical Society, 2022-02-28)
      Depending on the stellar densities, protoplanetary discs in stellar clusters undergo: background heating; disc truncation-driven by stellar encounter; and photo-evaporation. Disc truncation leads to reduced characteristic ...

    • Planetary core formation via multispecies pebble accretion 

      Andama, Geoffrey; Ndugu, Nelson; Anguma, Simon Katrini; Jurua, Edward (Oxford University Press, 2021-12-02)
      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 isolation mass, at which it induces a pressure ...

    • Which stars can form planets: Planetesimal formation at low metallicities 

      Andama, Geoffrey; Mah, Jingyi; Bitsch, Bertram (EDP Sciences, 2024-01-26)
      The diversity of exoplanets has been linked to the disc environment in which they form, where the host star metallicity and the formation pathways play a crucial role. In the context of the core accretion paradigm, the ...
