S6 - C.Fontanive, The effects of binary companions on planet formation and evolution
16 Novembro 2022, 14:00 • Maria Margarida Cruz
Abstract: While numerous exoplanets have now been uncovered in
stellar binaries, the impact of companion stars on planet formation and
evolution is still not understood. In this talk, I will present results
of population trends seen among the known sample of planets in multiple
star systems, which allows us to investigate the effects of stellar
binarity on the resulting planetary architectures. In particular,
observations of stars hosting high-mass close-in giant planets find an
excess of binary companions on few hundred AU separations, suggesting
that such systems may provide favourable conditions for the formation of
the observed inner companions. I will also show results from
simulations of circumstellar disks adapted to binary star environments,
which indicate that certain binary configurations may help trigger the
formation of giant planets.
