Really enjoying Dr. Shreyas Vissapragada's @carnegiescience.bsky.social seminar on three population-level surveys of atmospheric escape @oxoplanets.bsky.social!

My 15th Science Olympiad National tournament as part of the Astronomy event led by the fearless Donna Young — as usual, we’re hard at work proctoring and marking 60 exams, making it as fun as possible for the students (and ourselves!).

After a presentation of the Block award to Kimberly Paragas, we finished up our talks today with Daphne Broski-Laing presenting JWST phase curve observations of WD-BD binaries and Ted Johnson discussing studying planetary atmospheres with variable planetary infrared excess.

To kick off the last day of the meeting we have @johndebes.bsky.social and @sabrinapoulsen.bsky.social presenting results of JWST surveys searching white dwarfs for planets. There's a range of interesting targets that warrant follow-up!

Finishing off the day of talks before the conference banquet we have Ryan Challener showing 2D and 3D eclipse maps of WASP-43b and Jean-Baptiste Ruffio presenting the transformative capability of the JWST/NIRSpec IFU for characterizing directly imaged gas giant exoplanets.

Finishing off our morning session with Brianna Lacy showing model predictions for the viewing angle effects on late T and Y dwarfs and Michael Zhang showing the first JWST phase curve of a pulsar planet.

Continuing after the coffee break with Jerry Xuan telling us about volatile-to-refractory abundance ratios in the HR 8799 planets and Arthur Adams showing us JWST time-resolved observations of 2M 1207b!

Starting off Thursday with @astrorickman.bsky.social and Kielan Hoch telling us about space-based direct imaging of substellar objects -- Emily Rickman presented her recent Cycle 3 GO results, and Kielan is telling us about directly detecting silicate clouds in a multi-planet system.

Loving the public lecture by Prof. Zach Berta-Thompson (UC Boulder) @aspenphysics.bsky.social on The Glow of Distant Worlds. I’m especially enthralled by the IR camera, projector spectrum, and terrarium demos!

Finishing off our conference talks today with Kristin Sotzen and Reza Ashtari from @jhuapl.bsky.social telling us about applying PIE to JWST data and AI-based JWST data processing, respectively.

Continuing after the morning break with two talks on gas giants: Taylor Bell on a panchromatic JWST spectrum of WASP-80b and Lisa Dang on the enigmatic CoRoT-2b.

Kicking off Wednesday morning @aspenphysics.bsky.social with Drake Deming presenting lessons from Spitzer and Hubble thermal emission and Joost Wardenier presenting the recently observed WASP-76b phase curve.

We wrap up our talks today with two theorists, Maria Steinrueck and Isaac Malsky, presenting the impacts of photochemical hazes and the coupled impact of clouds and hazes, respectively for GJ 1214b. Their papers were recently posted to arXiv: arxiv.org/abs/2503.22642, arxiv.org/abs/2503.22608.

We finish our morning session with some interesting new JWST datasets of Neptunes and sub-Neptunes: Pierre-Alexis Roy showing the thermal emission spectrum of a hot and high-density sub-Neptune, and Michael Radica showing highlights from the NIRISS NEAT GTO team.

After a snowy conference photo outside @aspenphysics.bsky.social, we continue with terrestrial planet atmospheric dynamics with talks by Christopher Wirth on day-night heat transport on hot rocky planets and Eric Wolf on GCMs of temperate terrestrial exoplanets.

Starting off Day 2 in the winter wonderland of @aspenphysics.bsky.social with Renyu Hu telling us about the thermal emission of 55 Cancri e and Brandon Park Coy describing population-level hypothesis testing with rocky planet emission data.

After an afternoon of skiing/tubing/co-working at Snowmass, we finished off Day 1 with Kimberly Paragas telling us about smashing rock samples and taking their spectra and Amélie Gressier showing the thermal emission from the NIRSpec phase curve of K2-141b. More rocky planets tomorrow for Day 2!

After the morning coffee break we continued the theme of searching for atmospheres on planets around M dwarfs with Ben Rackham telling us about stellar activity, Sebastian Zieba's results on LHS 3844b, Megan Weiner Mansfield on survey strategies for the DDT, and Pat Wachiraphan on LTT 1445Ab.

Nestor Espinoza and Hannah Diamond-Lowe kicked off the 2025 Aspen Center for Physics meeting on Atmospheric characterization of rocky to giant exoplanets in thermal emission with JWST with two excellent talks on the rocky worlds DDT and the hot rocks survey. Looking forward to a great meeting!
