The evolution of hierarchical triple star-systems
S. Toonen, A. Hamers, S. Portegies Zwart
Field stars are frequently formed in pairs, and many of these binaries are part of triples or even higher-order systems. Even though, the principles of single stellar evolution and…
White dwarf pollution by planets in stellar binaries
Adrian S. Hamers, Simon F. Portegies Zwart
Approximately of white dwarfs (WDs) show signs of pollution by metals, which is likely due to the accretion of tidally disrupted planetary material. Models invoking p…
Secular dynamics of multiplanet systems: implications for the formation of hot and warm Jupiters via high-eccentricity migration
Adrian S. Hamers, Fabio Antonini, Yoram Lithwick +2
Hot Jupiters (HJs) are Jupiter-like planets that reside very closely to their host star, within . Their formation is not well understood. It is generally bel…
Dynamical constraints on the origin of hot and warm Jupiters with close friends
Fabio Antonini, Adrian S. Hamers, Yoram Lithwick
Gas giants orbiting their host star within the ice line are thought to have migrated to their current locations from farther out. Here we consider the origin and dynamical evolutio…
Mass transfer between debris discs during close stellar encounters
Lucie Jilkova, Adrian S. Hamers, Michael Hammer +1
We study mass transfers between debris discs during stellar encounters. We carried out numerical simulations of close flybys of two stars, one of which has a disc of planetesimals…
