nice. these posteriors imply K2-18 b's atmosphere could be anywhere from 0 to 100% DMDS (and same for the other molecules)

exciting news Ames and Goddard employees - you get to move to Alabama!

With access to multiple volatile and refractory species, we were able to measure the C/O AND refractory/volatile ratios, both of which appear to be superstellar. Comparing to Yayaati Chachan's disk models, this seems to be most consistent with formation b/t the soot line and H2O snow line-weird! 6/8

Yes, UHJs are hot enough that the "rocks" are actually gas! Typically, we look for these in optical wavelengths, but motivated by recent NIR Fe detections with CRIRES+ (see e.g. Swaetha Ramkumar's paper on MASCARA-1 b) we searched for the refractories... and found them! 5/8

The bread and butter of NIR exoplanet spectroscopy are the molecules H2O, CO, and OH, all three of which we see using standard cross-correlation methods. However, they're all at different velocities!! This is a wonderful reminder that planets are, in fact, three dimensional objects. 3/8

Today, we're taking a look at WASP-121 b, one of the prototypical UHJs that's still enigmatic today. We have both pre-eclipse data from the Marshmallows survey and post-eclipse data graciously shared by @astronemly.bsky.social from a queue program. Look how close the planet is to the star! 2/8

in the beginning the twitter clone releases were spaced apart 24 weeks. then 12, then 6, then every 2 weeks. the last one was a week. in 4 days we could be seeing a new twitter clone every 8 hours until they’re coming every 4 minutes
