Five key exoplanet questions answered via the analysis of 25 hot-Jupiter atmospheres in eclipse

Q Changeat, B Edwards, AF Al-Refaie… - The Astrophysical …, 2022 - iopscience.iop.org
Population studies of exoplanets are key to unlocking their statistical properties. So far, the
inferred properties have been mostly limited to planetary, orbital, and stellar parameters …

TESS transit timing of hundreds of hot Jupiters

ES Ivshina, JN Winn - The Astrophysical Journal Supplement …, 2022 - iopscience.iop.org
We provide a database of transit times and updated ephemerides for 382 planets based on
data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported …

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 …

Empirical limb-darkening coefficients and transit parameters of known exoplanets from TESS

JA Patel, N Espinoza - The Astronomical Journal, 2022 - iopscience.iop.org
Although the main goal of the Transiting Exoplanet Survey Satellite (TESS) is to search for
new transiting exoplanets, its data can also be used to study already-known systems in …

Detection of the tidal deformation of WASP-103b at 3 σ with CHEOPS

SCC Barros, B Akinsanmi, G Boué, AMS Smith… - Astronomy & …, 2022 - aanda.org
Context. Ultra-short period planets undergo strong tidal interactions with their host star which
lead to planet deformation and orbital tidal decay. Aims. WASP-103b is the exoplanet with …

Visible-light Phase Curves from the Second Year of the TESS Primary Mission

I Wong, D Kitzmann, A Shporer, K Heng… - The Astronomical …, 2021 - iopscience.iop.org
We carried out a systematic study of full-orbit phase curves for known transiting systems in
the northern ecliptic sky that were observed during Year 2 of the TESS primary mission. We …

ExoClock Project. II. A large-scale integrated study with 180 updated exoplanet ephemerides

A Kokori, A Tsiaras, B Edwards… - The Astrophysical …, 2022 - iopscience.iop.org
The ExoClock project is an inclusive, integrated, and interactive platform that was developed
to monitor the ephemerides of the Ariel targets to increase the mission efficiency. The project …

The continuing search for evidence of tidal orbital decay of hot Jupiters

KC Patra, JN Winn, MJ Holman, M Gillon… - The Astronomical …, 2020 - iopscience.iop.org
Many of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot
Jupiter for which orbital decay has been directly detected is WASP-12, for which transit …

Assessing the C/O Ratio Formation Diagnostic: A Potential Trend with Companion Mass

KKW Hoch, QM Konopacky, CA Theissen… - The Astronomical …, 2023 - iopscience.iop.org
The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a
potential diagnostic of planet formation. Now that a number of exoplanets have measured …

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 …
