#exo3 Glad Dr. Günther highlighted the link between flares and the habitability of M dwarf planets! Flares can be sneaky. The widely acclaimed "boring" M dwarf GJ 887 looks flare-less in TESS data, but not so in the far ultraviolet!

It's so nice to live a life free of #racism. My residence (#Tempe), my career (#astronomy), and especially my hobbies (#climbing) – not an ounce of hate in any! Curious, isn't it, that they're all almost entirely white?

One last #SPUV abstract: Brown et al. found Joule heating is influencing Saturn's outer atmosphere. I wonder, could Joule heating also play a role exoplanet atmospheric escape? For details on the rescheduled #SPUV, go to eiseverywhere.com/ultraviole…

A reminder from Moore & Cowan a la #SPUV that the lower boundary condition to a planetary atmosphere is not as simple as we scientists often like to make it. In short: rocks "breathe."
Another #SPUV highlight: Fleury et al. are making hot giant planet atmospheres in the lab!
Another #SPUV highlight: This question has been on my find for a while. Teal et al. have been testing what uncertainties in stellar UV spectra mean for photochemical models of planetary atmospheres. Can we fudge the UV or not? I hope to find out at the rescheduled SPUV 2021!
ALT We use a coupled 1D photochemistry and climate model to study the impact of uncertainties in host star UV spectra using the MUSCLES Treasury Survey. We also reconstruct these spectra using UV scaling relations to quantify the errors induced in photochemical modeling if the host star UV emission is not known a priori.
#SPUV might be delayed, but COVID can't stop us from tweeting some exciting SPUV science. SPUV would have (and will!) bring solar system and "exo system" scientists together. A solar system example: we can use UV light to detect surface carbon on Mercury, say Vilas et al.
I'm going to pick out my five favorite abstracts and post one per day this week!
Dear UV Enthusiasts, Today would have been the first day of the "Stars and Planets in the Ultraviolet" symposium @ASU, but we postponed to May 3-5, 2021. However, we posted the submitted abstracts we would have heard about this week here: #SPUV
ENJOY!
