Stellar contamination of the transmission spectrum of transiting exoplanets is emerging as a major challenge to the detailed atmospheric characterization of exoplanetary atmospheres. We are organizing a workshop to explore the impact of the transit light source effect on transmission spectra around different host stars and identify methods capable of correcting for this contamination.

The workshop will be part of the NExSS Workshops without Walls: an online workshop open to the entire community.
