Tidal dissipation in evolving low-mass and solar-type stars with predictions for planetary orbital decay
AJ Barker - Monthly Notices of the Royal Astronomical Society, 2020 - academic.oup.com
We study tidal dissipation in stars with masses in the range 0.1–1.6 M⊙ throughout their
evolution, including turbulent effective viscosity acting on equilibrium tides and inertial …

WASP-121 b: a hot Jupiter close to tidal disruption transiting an active F star
We present the discovery by the WASP-South survey of WASP-121 b, a new remarkable
short-period transiting hot Jupiter. The planet has a mass of M Jup, a radius of 1.865±0.044 …

Departure from the constant-period ephemeris for the transiting exoplanet WASP-12 b
Aims. Most hot Jupiters are expected to spiral in toward their host stars because the angular
momentum of the orbital motion is transferred to the stellar spin. Their orbits can also …

HATS-6b: a warm Saturn transiting an early M dwarf star, and a set of empirical relations for characterizing K and M dwarf planet hosts
We report the discovery by the HATSouth survey of HATS-6b, an extrasolar planet transiting
a V= 15.2 mag, i= 13.7 mag M1V star with a mass of 0.57${{M} _ {\odot}} $ and a radius of …

Orbital decay of hot jupiters due to nonlinear tidal dissipation within solar-type hosts
We study the orbital evolution of hot Jupiters due to the excitation and dam** of tidally
driven g-modes within solar-type host stars. Linearly resonant g-modes (the dynamical tide) …

Evidence of long-term period variations in the Exoplanet Transit Database (ETD)
SR Hagey, B Edwards, AC Boley - The Astronomical Journal, 2022 - iopscience.iop.org
We analyze a large number of citizen science data and identify eight hot Jupiter systems that
show evidence for deviations from a constant orbital period: HAT-P-19 b, HAT-P-32 b, TrES …
