“Modelling tidal decay of hot Jupiters through wave breaking”

mgr Jan Golonka
Instytut Astronomii, Uniwersytet Mikołaja Kopernika

Streszczenie:
Tidal interactions shape the evolution of close-in giant planets and internal gravity-wave breaking offers an efficient pathway for dynamical-tide dissipation, although its population-wide impact remains poorly constrained. In this talk I will focus on detailed predictions of wave-breaking for a large sample of hot Jupiter systems, discussing both population level trends and results for individual systems. These include predictions for currently operating tidal interactions, and simulations of the orbital evolution of known hot Jupiters until their engulfment or disruption by their host star. Additionally I will present the results of my follow-up observations dedicated to testing the predicted shifts in central times of transits from tidal theory.
