A very cool result! Julo+ with a paper on “Stellar halo subtraction … with integral field spectroscopy… on the PDS70, HTLup, and YSES1 systems” showing that the YSES 1b #exoplanet has a lot of emission lines - H alpha , H beta, He I, Ca H and K triplets, Na in absorption… oh my! #astrodon ☄

Two spectra of the planet YSES 1b. The left hand spectrum shows a huge peak of Hydrogen alpha emission, and the right hand spectrum shows Calcium II triplet in emission, next to a fuzzy Sodium absorption feature.
