A Spatial Map of the Atmospheric Limb of a Hot Jupiter

Lili Alderson, Hannah R. Wakeford, David Grant +18

Planets are inherently three-dimensional objects shaped by their thermal structure and dynamics. Observations of transiting exoplanets have begun to uncover this three-dimensional…

The asymmetric limbs of HD 209458 b observed with JWST NIRCam F322W2/F444W

Cathal Maguire, Eva-Maria Ahrer, Charlotte Fairman +6

We present a reanalysis of JWST NIRCam F322W2/F444W transit observations of the hot Jupiter HD 209458 b to extract morning and evening transmission spectra. To determine whether as…

JWST-TST DREAMS: Sulfur dioxide in the atmosphere of the Neptune-mass planet HAT-P-26 b from NIRSpec G395H transmission spectroscopy

Amélie Gressier, Natasha E. Batalha, Nicholas Wogan +24

We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with th…

New perspectives on MASCARA-1b: A combined analysis of pre- and post-eclipse emission data using CRIRES+

Swaetha Ramkumar, Neale P. Gibson, Stevanus K. Nugroho +2

We present high-resolution emission spectroscopy observations of the ultra-hot Jupiter MASCARA-1b with CRIRES+ in the K-band, covering the post-eclipse phases of its orbit. These o…

High-resolution atmospheric retrievals of WASP-76b transmission spectroscopy with ESPRESSO: Monitoring limb asymmetries across multiple transits

Cathal Maguire, Neale P. Gibson, Stevanus K. Nugroho +4

Direct atmospheric retrievals of exoplanets at high-resolution have recently allowed for a more detailed characterisation of their chemistry and dynamics from the ground. By monito…

How do wavelength correlations affect transmission spectra? Application of a new fast and flexible 2D Gaussian process framework to transiting exoplanet spectroscopy

Mark Fortune, Neale P. Gibson, Daniel Foreman-Mackey +3

The use of Gaussian processes (GPs) is a common approach to account for correlated noise in exoplanet time series, particularly for transmission and emission spectroscopy. This ana…
