Inhomogeneous Cloud Coverage and Altitude-Dependent Heat Transport on the Hot-Jupiter NGTS-10 Ab from its Optical-to-Infrared Phase Curve
Louis-Philippe Coulombe, Vivien Parmentier, Kevin B. Stevenson +15
Hot-Jupiters, gas giant planets with equilibrium temperatures above 1,000 K, host large temperature gradients between their permanent day- and nightsides, resulting in circulation…
Breaking the brightness barrier: JWST/NIRCam DHS spectroscopy for high-precision time-series observations
Achrene Dyrek, John Stansberry, Louis E. Bergeron +12
Many of the most scientifically compelling exoplanets orbit bright nearby stars that exceed the brightness limits of existing JWST spectroscopic observing modes. To address this li…
slicersim: A python package to simulate image slicer spectroscopic observations -- application to the Lazuli Spectrograph
M. Rigault, Y. Copin, G. Aldering +8
Integral Field Spectroscopy (IFS) is a key technique to study galaxies, stellar and planetary systems, and transients, by spatially splitting the scene and dispersing this light on…
Horizontal transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet
Vivien Parmentier, Kevin B. Stevenson, Luis Welbanks +15
Hot Jupiters have temperature gradients of several hundreds of degrees between their permanent day and nightsides. In equilibrium, the primary carbon reservoir is expected to trans…
The tale of the 3 planets: 3D cloud feedback enhances the spectral diversity of warm Jupiters
Nishil Mehta, Vivien Parmentier, Xianyu Tan +14
JWST has shown a large diversity in warm Jupiter spectra, despite only small variations in the planetary parameters. However, the main driver of this diversity remains unclear. We…
The Identification of CS2 and Evidence for Carbon-Sulfur Chemical Coupling in a Warm Giant Exoplanet Atmosphere
Anastasia Triantafillides, Thomas G. Beatty, Matthew C. Nixon +14
Transmission spectroscopy with the James Webb Space Telescope (JWST) is revealing growing chemical complexity in giant exoplanet atmospheres. Of particular interest is sulfur, whic…
