The formation of planetary systems: physics, populations, and architectures

Andrin Kessler, Jesse Weder, Jesse Polman +5

We review the progresses made in global theoretical models of planetary system formation in the last decade using the example of the planetary system formation framework known as t…

The PAIRS project: a global formation model for planets in binaries. II. Gravitational perturbation effects from secondary stars

Arianna Nigioni, Julia Venturini, Emeline Bolmont +3

Roughly half of Sun-like stars have at least one stellar companion, whereas it is widely assumed that most known exoplanets orbit single stars, largely due to observational biases.…

The PAIRS project: a global formation model for planets in binaries. I. Effect of disc truncation on the growth of S-type planets

Julia Venturini, Arianna Nigioni, Maria Paula Ronco +2

Binary stars are as common as single stars. The number of detected planets orbiting binaries is rapidly increasing thanks to the synergy between transit surveys, Gaia and high-reso…

DIPSY: A new Disc Instability Population SYnthesis, II. The Populations of Companions Formed Through Disc Instability

O. Schib, C. Mordasini, A. Emsenhuber +1

We applied the global end-to-end model described in Paper~I of this series to perform a population synthesis of companions formed via disc instability (DI). By using initial condit…

DIPSY: A new Disc Instability Population SYnthesis, I. Modeling, evolution of individual systems, and tests

O. Schib, C. Mordasini, A. Emsenhuber +1

Disc instability (DI) is a model aimed at explaining the formation of companions through the fragmentation of the circumstellar gas disc. Furthermore, DI could explain the formatio…

The New Generation Planetary Population Synthesis (NGPPS). VII. Statistical comparison with the HARPS/Coralie survey

Alexandre Emsenhuber, Christoph Mordasini, Michel Mayor +8

We seek to quantify the fidelity with which modern population syntheses reproduce observations in view of their use as predictive tools. We compared synthetic populations from the…
