POSEIDON: A Multidimensional Atmospheric Retrieval Code for Exoplanet Spectra
Spectroscopic observations of exoplanet atmospheres can reveal the chemical composition, temperature, cloud properties, and (potentially) the habitability of these distant worlds. The inference of such properties is generally enabled by […]

Sealing Europa’s Vents By Vapor Deposition: An Order Of Magnitude Study
Fractures and vents in the ice crust of Europa, exposing the sub-surface ocean to the vacuum, might be responsible for the generation of planetary-scale water-vapor plumes.

A Search For Water Vapor Plumes On Europa By spatially Resolved Spectroscopic Observation Using Subaru/IRCS
We present near-infrared high-dispersion spectroscopic observations of Europa using the Infrared Camera and Spectrograph (IRCS) onboard the Subaru Telescope, seeking direct evidence of water plumes on Europa and exploring spatial […]

JWST/NIRISS and HST: Exploring The Improved Ability to Characterise Exoplanet Atmospheres In The JWST Era
The Hubble Space Telescope has been a pioneering instrument for studying the atmospheres of exoplanets, specifically its WFC3 and STIS instruments. With the launch of JWST, we are able to […]

Investing in the Unrivaled Potential of Wide-Separation Sub-Jupiter Exoplanet Detection and Characterisation with JWST — Strategic Exoplanet Initiatives with HST and JWST White Paper
We advocate for a large scale imaging survey of nearby young moving groups and star-forming regions to directly detect exoplanets over an unexplored range of masses, ages and orbits. Discovered […]

Probing the Heights and Depths of Y Dwarf Atmospheres: A Retrieval Analysis of the JWST Spectral Energy Distribution of WISE J035934.06−540154.6
We present an atmospheric retrieval analysis of the Y0 brown dwarf WISE J035934.06−540154.6 using the low-resolution 0.96–12 μm JWST spectrum presented in Beiler_2023. We obtain volume number mixing ratios of […]
