We are restarting #CHEXO #Exoplanet meetings in the DMV+ area!
We'll be having #CHEXO11 @stsci in Baltimore on Friday May 17th 2024 (abstracts due Today). All day, no fees.

YA WEY, CINCO ABANDONOS MÁS Y CHEQUITO P1 ALV!! 💪😎
#AusGP
Signals are large, but transits are short (minutes), so need multiple transits and JWST is still going to bill your for a whole hour.... 50 transits gets you N2, N2O, CH4, O3 and H2O and CO2, but need 100 for O2. Remember these are spread in time by orbital period #CHEXO
So if a planet survives it is could be straightforward for atmospheric characterization, and it'd be neat if the planet was in the new HZ by either migrating into it and survived the star (and then life survived or re-evolved on the planet...) #CHEXO
JWST will require years of observations to get at earth-like atmospheres around M-dwarfs. MacDonald suggests we go even smaller. WD1856+534b, e.g., is bigger than its white dwarf host. #CHEXO
Smaller stars mean that planets have proportionally larger signals in transmission spectroscopy, this is why rocky planets around M-dwarfs can be determined to be non-H/He dominated, but not yet other high mmw atmospheres (a la TRAPPIST-1) #CHEXO
Next up is @elenamanjavacas talking about vertical cloud structure of an AB Pic b analog through spectro-photometric variability #CHEXO
Next up is Carlos E. Cruz-Arce talking about simulating surface albedos for reflection spectra of rocky exoplanets. His favorite object in the Solar System is Enceladus #CHEXO
Teresa Monsue on quasi-periodic pulsations in stellar flares using NASA Swift data and TESS 20sec . Team includes postdocs Laura Vega and @rrpaudel18. Need high cadence data due to the short periods. #ChExo
We're back with with Teresa Monsue, talking about quasi-periodic pulsations (QPP) in stellar flares #CHEXO
They now have a social media presence. A youtube channel with demonstration videos and "unofficially" (this is from the website) @ExoplanetModels #CHEXO
There's a MyBinder tool which lets you quickly get started on a tool in a Jupyter notebook that already has it installed so you don't have to figure it out just to see if it'll work for you #CHEXO
Next up is Nick Susemiehl talking about the new enhancements to the exoplanet modeling analysis center, which is a repository for exoplanet related software. They've added a lot of tools recently (ours got requested to be added so we did). #CHEXO
Michael Meyer now describing brown dwarf binary distributions and gas giant exoplanet orbital distributions. Observed companions to A, G, M dwarfs can be seen as combinations of these two populations. "Brown dwarf 'desert' is expected local minimum" not mystery.
#ChExo
Daniel Apai shows his group's work on winds in the Luhman 16 brown dwarfs using TESS. In many ways the brown dwarf Lehman 16B looks similar to Jupiter. Check out the videos at https://t.co/eGfY31HPsM. #ChExo
Next up at #CHEXO we have @MartianColonist talking about planets around White Dwarfs....or at least he should be....
