I also have ALL the receipts from the grad student trip to the Long Beach AAS in 2013. I can probably toss these now lol. Although why *I* have them I don't know

Very thankful to my collaborators as I go through another #JWST cycle recovering from illness (not covid this time thankfully!). I managed to get my resubmits in and will have to hope I get a chance at next year for my new ideas.

Took stock of local EV charger rates to compare to home rate. Last time I did this they were at $0.17/kWh now its $0.38/kWh Looks like my home energy is still competitive at 0.22 but it used to be 0.16 🫠

These tests of our methodologies on Solar System objects, where we KNOW the answers are critical as we prepare for exoplanet data. We have a couple more papers coming down the pipeline that get into the modeling of Exo-Titans so keep an eye out!

Then we said, well what if we were looking at an Exo-Titan. If a planet like TRAPPIST-1h had a hazy Titan-like atmosphere could we figure out where the haze is and what it is made of?

Turns out that with JWST-like observations, both can get a good fit, but they have different guesses of what parameters it takes to make it. The models separate at the shortest wavelengths, which means observatories, like HWO, will have the data we'll need to figure out what haze is made of.

We looked at two exoplanet tools and put them to the test of on actual Titan. One with an actual physical haze particle prescription and another with a model of what haze does to a spectrum. This is our control! Both are able to get something resembling Titan with consistent parameters.

Samuel Grunblatt tackles asteroseismology with TESS. This can be difficult because single sector datasets are too short to retrieve pulsation signals. Asteroseismology not only enables refined masses and radii measurements but also ages. #exoplanets6 #exo6

Pietro Leonardi looks at the HIP 41378 system, which contains three transiting planets, def, in 7:5 resonance with period of 278d+ So some transits have never been seen again. #exoplanets6 #exo6

Niamh Mallaghan (which I don't know how to pronounce!) will close out the session with a talk on exoRings. ASASSN-21js is unusual in that it seems to *still* be transiting Plot from Pramono et al 2024! #exoplanets6 #exo6

If ring modeling is to be believed, we will never see another transit as the P>100kyrs. They recently acquired hires data and are trying to disentangle stellar, ISM, and disk spectral features. Mallaghan also has a poster on NOI 105872 and is on the postdoc market #exoplanets6 #exo6

Gaia Lacedelli examines the sub Neptune pop. Where recent works have tried to explain the formation of the savannah, ridge, and desert with various migration types. With espresso and supporting photometry they are looking at spin-orbit alignments as a tracer of migration #exoplanets6 #exo6

As room hopping continues, Morgan Saidel explains extreme mass loss not only affects the atmosphere but the escaped gas can torque the planet and change its orbit. Saidel attempts to build a survey of escaped gas structures with hires data. #exoplanets6 #exo6

Georgia Mraz looks at hires observations of uHJ WASP-33b as a function of phase. Due to the acceleration changes getting quadratic phases is difficult apparently. Looked at CO as a function of pre- and post- transit/eclipse. #exoplanets6 #exo6

As the room fills to the brim, Dario González Picos shows hires data of beta Pic b with support from photometry to break the cloud-metaliciity degeneracy. Finds a super color metallicity and solar-like C/O. The carbon isotopologue ratio would indicate it is very young. #exoplanets6 #exo6

As I give up fighting for wifi, Julia Seidel looks at winds in uHJs as a population study. In Seidel et al 2026, the data shows that the wind speeds are being damped as eqT increases. The theory is magnetic drag is dissipating energy. #exoplanets6 #exo6

Guo Chen looks at ultra-hot Jupiters in hires NIR spectra. As shown in Yang et al 2024 and submitted 2026 they find an inverted atmosphere and some tentative detections of various species. They've built a 3D parameterized model to infer phase offsets, temperatures, chemistry, etc #exoplanets6 #exo6

Engin Keles is looking for am atmosphere around 55 Cnc e with hires xc spectroscopy He posits that a variable atmosphere is present given the various detections and non detections #exoplanets6 #exo6

The Massive Exoplanet MEME Exhibition was here at #exoplanets6 #exo6 Their goal is to collect memes for use in engaging the public. Next exhibition is in January and they have been holding a contest here The youth have different memes! The memes have changed, I am elderly 😮‍💨

Jean-Michel Désert will "entertain" us with XUV flux impacts on atmospheric escape Particularly he'd like to apply multiple tracers to get around degeneracies but there is disagreement between tracers sometimes as in V1298 Tau c which is very young around a very active star #exoplanets6 #exo6

Among these science cases, searching for WD planets sticks out to me because the youngest WDs are super hot and that would catch their peak flux and what happens when you bake a planet like that?

The theory is that the planet could be a super Earth progenitor, i.e. it has much mass to lose yet The atmosphere doesn't appear to be in chemical equilibrium; the irradiation destroys methane and makes CO2 #exoplanets6 #exo6

Jared Kolecki attempts to convince us that stellar oxygen enrichment is a better predictor of giant planet formation rather than silicon using protoplanetary disk models #exoplanets6 #exo6

From 500 stellar abundance measurements they find a trend between stars with and without giant planets in [O/Fe] vs [Fe/H] space This paper is submitted. And the trend seems to hold across several other elements, but O is the strongest #exoplanets6 #exo6

Particularly at lower metallicities, there is almost 20% more O in the stars with giant planets At high metallicity, there is just so much stuff in the disk that you're gonna make some big planets anyway He's on the postdoc market! #exoplanets6 #exo6
