From this spectrum obtained with just one transit, we only slightly prefer the atmosphere over the stellar inhomogeneities. On the plus side, several different atmospheric setups and retrieval scenarios all come up with high H2S/SO2 abundances
The retrieved spectra for the main retrievals: Stellar + Atmosphere scenario is plotted in red, Atmosphere Only in blue, and Stellar Only in green. The 1σ and 2σ credible intervals are plotted in dark and light shades of the corresponding colors respectively. The NRS2 points are shifted by the retrieved offset, and the unshifted NRS2 points are shown in gray. Underneath the spectrum, in the first row from left to right, the retrieved posterior distributions for log(H2S), log(SO2), and Temperature are shown. In the second row, from left to right, the retrieved posterior distributions for fhet, Tphot, and ∆Thet are shown.

Spotting atmospheric signals on small planets is challenging. To add to that, sometimes stuff on the star (spots/faculae) can mimic those signals.

That counts as a Trappist transmission spectrum right? #exoplanets5

At #dotastro 13 at the ESAC in Madrid. A very different feel to regular conferences!

Loving it and looking forward to more

Also my first time in Spain!

Thanks #UKExom23 organisers for the chance to present this. Had a great time there! Check out the other threads from @drjovian.bsky.social for a live coverage of the talks
