Exoplanet Atmosphere Spectral Sensitivity Analysis with PICASO: Jacobians, Linear-Gaussian Approximations, and Information Content
Natasha E. Batalha, Nicholas F. Wogan
Designing observatory and instrument architectures for complex missions like the Habitable Worlds Observatory (HWO) requires a rapid and rigorous mathematical framework to evaluate…
Time-resolved JWST Retrieval Analysis of the Coldest Brown Dwarf: Temperature and Chemical Variations in WISE 0855-07
Harshil Kothari, Caroline V. Morley, Brittany E. Miles +12
WISE J0855-07 is the coldest known brown dwarf (estimated Teff~250 K), offering a rare opportunity to probe atmospheric physics in the temperature and mass regime that overlaps dir…
The Sonora Substellar Atmosphere Models. VII. Flame Skimmer: Cloud-free Atmospheric and Evolutionary Models for the Coldest Substellar Objects
James Mang, Yayaati Chachan, Caroline V. Morley +7
JWST has provided unprecedented access to ultra-cool brown dwarfs and has pushed the boundaries of directly imaging temperate giant planets. As we continue to push toward detecting…
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…
Impact of Clouds on the Atmosphere-Mantle Interface of Sub-Neptunes
Sagnick Mukherjee, Matthew C. Nixon, Luis Welbanks +4
Sub-Neptunes are among the most common type of close-in planets found in our galaxy, yet their bulk composition remains largely uncertain; H-rich envelopes overlaying rocky cores,…
JWST COMPASS Program: The 3--5m transmission spectrum of LTT 1445 A b
Natasha E. Batalha, Nicole Wallack, Tyler Gordon +16
The search for an atmosphere on the closest rocky M dwarf planet, LTT 1445 A b, has been the subject of intense investigation from both the ground and space. Here, we present the f…
A Climate-Constrained Bayesian Inverse Method for JWST Rocky Exoplanet Eclipse Spectra: A Case Study of LTT 1445A b
Nicholas Wogan, Natasha Batalha, Jegug Ih +2
Determining whether temperate rocky exoplanets orbiting M stars retain atmospheres is currently a central goal of exoplanet astronomy. To this end, the James Webb Space Telescope h…
Toward Inferring the Surface Fluxes of Biosignature Gases on Rocky Exoplanets from Telescope Spectra
Nicholas F. Wogan, Natasha E. Batalha, Joshua Krissansen-Totton +5
The James Webb Space Telescope and the future Habitable Worlds Observatory aim to discover exoplanet atmospheric spectra that detect life. Currently, most existing spectral "retrie…
Protosolar D-to-H abundance and one part-per-billion PH in the coldest brown dwarf
Melanie J. Rowland, Caroline V. Morley, Brittany E. Miles +24
The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (200 -- 400 K) giant exoplanets. We can therefore use their atmospheres as proxi…
High-Contrast Imaging at First-Light of the GMT: The Preliminary Design of GMagAO-X
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +15
We present the preliminary design of GMagAO-X, the first-light high-contrast imager planned for the Giant Magellan Telescope. GMagAO-X will realize the revolutionary increase in sp…
Report of the Working Group on Strategic Exoplanet Initiatives with HST and JWST
Seth Redfield, Natasha Batalha, Björn Benneke +7
This STScI Working Group (WG) was charged with soliciting community feedback and evaluating the strategic planning for exoplanet science with JWST and HST given the high quality of…
Modeling Atmospheric Lines By the Exoplanet Community (MALBEC) version 1.0: A CUISINES radiative transfer intercomparison project
Geronimo L. Villanueva, Thomas J. Fauchez, Vincent Kofman +15
Radiative transfer (RT) models are critical in the interpretation of exoplanetary spectra, in simulating exoplanet climates and when designing the specifications of future flagship…
Simulating medium-spectral-resolution exoplanet characterization with SCALES angular/reference differential imaging
Aditi Desai, Stephanie E. Sallum, Ravinder Banyal +30
SCALES (Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy) is a 2 - 5 micron high-contrast lenslet-based integral field spectrograph (IFS) designed to characterize…
The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES): driving science cases and expected outcomes
Steph Sallum, Andrew Skemer, Deno Stelter +34
