“Probing planet-star tidal interactions with precise transit timing of hot Jupiters”

mgr Jan Golonka (Instytut Astronomii, Uniwersytet Mikołaja Kopernika)

Streszczenie:
Hot Jupiters are gas giants on tight orbits around their host stars. Due to their high mass and close proximity, it is thoerised that they could induce tidal interactions with their host stars. An observational proof of these interactions could be a shift in transit times of the planet, caused by transfer of orbital angular momentum from the planet to the star. In this talk I will present my preliminary results from transit timing analysis of select objects, with the goal of putting observational constraints on theoretical predictions of tidal interactions.
