TRIDENT: A Rapid 3D Radiative Transfer Model for Exoplanet Transmission Spectra
Ryan J. MacDonald, Nikole K. Lewis
Transmission spectroscopy is one of the premier methods used to probe the temperature, composition, and cloud properties of exoplanet atmospheres. Recent studies have demonstrated…
Gemini/GMOS Transmission Spectroscopy of the Grazing Planet Candidate WD 1856+534 b
Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald +12
WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained fro…
A comprehensive revisit of select Galileo/NIMS observations of Europa
Ishan Mishra, Nikole Lewis, Jonathan Lunine +4
The Galileo Near Infrared Mapping Spectrometer (NIMS) collected spectra of Europa in the 0.7-5.2 m wavelength region, which have been critical to improving our understanding of…
The Emission Spectrum of the Hot Jupiter WASP-79b from HST/WFC3
Trevor O. Foote, Nikole K. Lewis, Brian M. Kilpatrick +12
Here we present a thermal emission spectrum of WASP-79b, obtained via Hubble Space Telescope Wide Field Camera 3 G141 observations as part of the PanCET program. As we did not obse…
Differentiating Modern and Prebiotic Earth Scenarios for TRAPPIST-1e: High-resolution Transmission Spectra and Predictions for JWST
Zifan Lin, Ryan J. MacDonald, Lisa Kaltenegger +1
The TRAPPIST-1 system is a priority target for terrestrial exoplanet characterization. TRAPPIST-1e, residing in the habitable zone, will be observed during the JWST GTO Program. He…
ACCESS & LRG-BEASTS: a precise new optical transmission spectrum of the ultrahot Jupiter WASP-103b
James Kirk, Ben Rackham, Ryan MacDonald +17
We present a new ground-based optical transmission spectrum of the ultrahot Jupiter WASP-103b (K). Our transmission spectrum is the result of combining five new tran…
HST PanCET Program: A Complete Near-UV to Infrared Transmission Spectrum for the Hot Jupiter WASP-79b
Alexander D. Rathcke, Ryan J. MacDonald, Joanna K. Barstow +12
We present a new optical transmission spectrum of the hot Jupiter WASP-79b. We observed three transits with the STIS instrument mounted on HST, spanning 0.3 - 1.0 um. Combining the…
A Spectral Survey of WASP-19b with ESPRESSO
Elyar Sedaghati, Ryan J. MacDonald, Núria Casasayas-Barris +10
High resolution precision spectroscopy provides a multitude of robust techniques for probing exoplanetary atmospheres. We present multiple VLT/ESPRESSO transit observations of the…
ACCESS: An optical transmission spectrum of the high-gravity, hot Jupiter HAT-P-23b
Ian C. Weaver, Mercedes López-Morales, Munazza K. Alam +11
We present a new ground-based visible transmission spectrum of the high-gravity, hot Jupiter HAT-P-23b, obtained as part of the ACCESS project. We derive the spectrum from five tra…
