Mind the gap: Distinguishing disc substructures and their impact on the inner disc composition

Jingyi Mah, Sofia Savvidou, Bertram Bitsch

Improved observational technologies have enabled the resolution of substructures and the measurement of chemical abundances in discs. Understanding the chemical composition of the…

Which stars can form planets: Planetesimal formation at low metallicities

Geoffrey Andama, Jingyi Mah, Bertram Bitsch

The exoplanet diversity 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 o…

Composition of giant planets: the roles of pebbles and planetesimals

Claudia Danti, Bertram Bitsch, Jingyi Mah

One of the current challenges of planet formation theory is to explain the enrichment of observed exoplanetary atmospheres. Past studies have focused on scenarios where either pebb…

Enriching inner discs and giant planets with heavy elements

Bertram Bitsch, Jingyi Mah

Giant exoplanets seem to have on average a much larger heavy element content than the solar system giants. Past attempts to explain these heavy element contents include collisions…

Close-in ice lines and the super-stellar C/O ratio in discs around very low-mass stars

J. Mah, B. Bitsch, I. Pascucci +1

The origin of the elevated C/O ratios in discs around late M dwarfs compared to discs around solar-type stars is not well understood. Here we endeavour to reproduce the observed di…

Forming super-Mercuries: The role of stellar abundances

J. Mah, B. Bitsch

Super-Mercuries, rocky exoplanets with bulk iron mass fraction of more than 60 per cent, appear to be preferentially hosted by stars with higher iron mass fraction than the Earth.…
