TSD: An inverse problem approach for recovering the exoplanetary atmosphere transmission spectrum from high-resolution spectroscopy
The episode discusses Nikolai Piskunov's paper, "TSD: An inverse problem approach for recovering the exoplanetary atmosphere transmission spectrum from high-resolution spectroscopy." The hosts discuss how TSD uses orbital Doppler shifts and modeling physical noise instead of pre-made templates to extract planetary signals. They conclude that while computationally intensive, this method offers a more objective way to characterize exoplanetary atmospheres.
