For about three years, it was known that precision spectrophotometry with FORS2 suffered from systematic errors that made quantitative observations of planetary transits impossible. We identified the Longitudinal Atmospheric Dispersion Compensator (LADC) as the most likely culprit, and therefore engaged in a project to exchange the LADC prisms with the uncoated ones from FORS1. This led to a significant improvement in the depth of FORS2 zero points, a reduction in the systematic noise, and should make FORS2 again competitive for transmission spectroscopy of exoplanets.

  1. LRG-BEASTS: transmission spectroscopy and retrieval analysis of the highly-inflated Saturn-mass planet WASP-39b

    astro-ph.EP 2019-08 conditional novelty 6.0 of 10

    A combined analysis of all WASP-39b transmission spectra with one equilibrium-chemistry retrieval code yields an atmospheric metallicity of roughly 280 times solar and attributes literature scatter to retrieval assumptions.
