Disentangling Metallicity Effects in Hot Jupiter Occurrence across Galactic Birth Radius and Phase-space Density

The Astronomical Journal
We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius ( R _birth ) and phase-space density in the Milky Way disk.

THERMODYNAMICS OF ATMOSPHERIC CIRCULATION ON HOT JUPITERS [PDF]

The Astrophysical Journal, 2009
Atmospheric circulation on tidally-locked exoplanets is driven by the absorption and reradiation of heat from the host star. They are natural heat engines, converting heat into mechanical energy. A steady state is possible only if there is a mechanism to dissipate mechanical energy, or if the redistribution of heat is so effective that the Carnot ...

Limited Hysteresis in the Atmospheric Dynamics of Hot Jupiters

The Astrophysical Journal
Over the past two decades, a coherent picture has emerged of the atmospheric dynamics of hot Jupiters from a combination of three-dimensional general circulation models and astronomical observations.

Probing the Possible Causes of the Transit Timing Variation for TrES-2b in the TESS Era

The Astronomical Journal
Nowadays, transit timing variations (TTVs) are proving to be a very valuable tool in exoplanetary science to detect exoplanets by observing variations in transit times. To study the TTV of the hot Jupiter TrES-2b, we have combined 64 high-quality transit

Eight New Candidate Multiplanet Systems among TESS Objects of Interest

The Astronomical Journal
We present a search of the TESS Object of Interest (TOI) Catalog for new multiplanet systems. We perform a Box Least Squares search on light curves prepared by the Quick-Look Pipeline to recover known candidates and perform a targeted search for ...

The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201

The Astrophysical Journal Letters
Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities of FGK stars with hot Jupiters, mainly based on observations of the ...

Observations of Hot-Jupiter occultations combining Spitzer and Kepler photometry

EPJ Web of Conferences, 2011
We present the status of an ongoing program which aim at measuring occultations by their parent stars of transiting hot giant exoplanets discovered recently by Kepler. The observations are obtained in the near infrared with WarmSpitzer Space Telescope
