Last talk before the break: Sarah Millholland on empirical constraints on tidal dissipation in exoplanets host stars.

Close in planets are subjected to heavy tides that are circularising the orbits quickly. Stellar tides cause orbital decay for close-in planets.

But we don‘t know the dominant tidal mechanism and how efficient they are! Equilibrium? Dynamical (waves?)?

To overcome this problem, they use the approach to look at the decay timescale. See maths below 👇
