JWST-TST High Contrast: First Direct Spectroscopy of GJ 504 b reveals Clouds and Possible Metal Enrichment

Aneesh Baburaj, Jean-Baptiste Ruffio, Marshall Perrin +27

Characterizing the coldest directly imaged companions through direct spectroscopy has only recently become possible with the James Webb Space Telescope. We present moderate-resolut…

High-contrast L-band Integral Field Spectroscopy of HD 33632 Ab

Jordan M. Stone, Steve Ertel, Travis Barman +5

We present LBTI/ALES 3.07-4.08 micron spectroscopic observations of HD~33632~Ab, a ~53 M_Jup directly imaged companion to an F8 star. Spectroscopic measurements of HD 33632 Ab now…

Effects of Ultraviolet Radiation on Sub-Neptune Exoplanet Hazes Through Laboratory Experiments

Lori Huseby, Sarah E. Moran, Neil Pearson +9

Temperate sub-Neptune exoplanets could contain large inventories of water in various phases, such as water-worlds with water-rich atmospheres or even oceans. Both space-based and g…

Water absorption in the transmission spectrum of the water-world candidate GJ9827d

Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +16

Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than often host H…

Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager

Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne +49

HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved obs…
