On the Compositions of Interstellar Objects

Matthew J. Hopkins, Michele T. Bannister, Bertram Bitsch +2

As physical samples of distant planetary systems, the compositions of interstellar objects (ISOs) should correlate with the properties of their diverse parent stars. We combine a c…

Planetary gas gaps and kinematic signatures in the planet forming disk around WISPIT 2

Nienke van der Marel, Jochen Stadler, Andres F. Izquierdo +8

The giant planet formation process in disks of gas and dust surrounding young stars is observationally still poorly constrained. Direct detection of protoplanets within the disk re…

How disc initial conditions sculpt the atmospheric composition of giant planets

Angie Daniela Guzmán Franco, Sofia Savvidou, Bertram Bitsch

Past studies have revealed the dependency of the disc parameters (mass, radius, viscosity, grain fragmentation velocity, dust-to-gas ratio) on the formation of giant planets, where…

Heavy element enriched atmospheres and where they are born

Barry O'Donovan, Bertram Bitsch

The heavy element content of giant exoplanets, inferred from structure models based on their radius and mass, often exceeds predictions based on classical core accretion. Pebble dr…

The SPACE Program. I. The featureless spectrum of HD 86226 c challenges sub-Neptune atmosphere trends

K. Angelique Kahle, Jasmina Blecic, Reza Ashtari +26

Sub-Neptune exoplanets are the most abundant type of planet known today. As they do not have a Solar System counterpart, many open questions exist about their composition and forma…

How does the chemical composition of solids influence the formation of planetesimals?

Konstantinos Odysseas Xenos, Bertram Bitsch, Geoffrey Andama

The formation of planetesimals is a necessary step in the formation of planets. While several mechanisms have been proposed, a local dust-to-gas ratio above unity is a strong requi…
