Hot Jupiters are destroyed by tides while their host stars are on the main sequence

JH Hamer, KC Schlaufman - The Astronomical Journal, 2019 - iopscience.iop.org
While cooler giant planets are often observed with nonzero eccentricities, the short-period
circular orbits of hot Jupiters suggest that they lose orbital energy and angular momentum …
