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…

Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Ana Glidden, Alexander I. Shapiro, Sara Seager +19

Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of sp…

Veiled in Starlight: Impacts of Stellar Contamination on Retrievals of TRAPPIST-1f's Atmospheric Composition

Harper Rosenthal, Lisa Kaltenegger, Ryan J. MacDonald +2

The TRAPPIST-1 system offers seven terrestrial exoplanets with tight orbits and large radii ratios to the host star. If an atmosphere exists, transmission spectroscopy can be used…

Aerosols and hydrocarbons in the atmosphere of a white dwarf planet

Ryan J. MacDonald, Christopher E. O'Connor, Victoria A. Boehm +15

Most stars, including our Sun, will one day evolve into red giants and, subsequently, white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs, d…

Magnesium Silicate Clouds in the Atmosphere of HD 209458b from a Rule-Based Tree-Structured Data Reduction

Katy L. Chubb, David Grant, Hannah R. Wakeford +14

HD 209458b is the canonical hot Jupiter: the first to have its atmosphere measured and the first to hint at the role of aerosols in exoplanet atmospheres through the muting of Na a…

The Rocky Planet Picture Show: Implementation of Surface Reflection and Emission in with Application to and Interpretation of JWST Data

Elijah Mullens, Ryan J. MacDonald, Marina E. Gemma +3

The surface characterization of rocky exoplanets via emission spectroscopy represents a frontier of current (JWST) and future (HWO) observational efforts. Here, we implement new fe…

Identifying Surface Degeneracies in Single-Visit Reflected Light Observations of Modern Earth using the Habitable Worlds Observatory

Aiden S. Zelakiewicz, Elijah Mullens, Lisa Kaltenegger +1

Characterizing the surface and atmosphere of Earth-like planets in reflected light is a key goal for upcoming direct imaging surveys. NASA's next flagship-class astrophysics missio…
