The Transit Light Source Effect: False Spectral Features and Incorrect Densities for M-dwarf Transiting Planets
TL;DR: In this paper, the Max Planck Institute for Astronomy, Heidelberg, Germany and NASA's Science Mission Directorate provided a grant for a study of the effect of solar radiation on the Earth's magnetic field.

TL;DR: A detection of helium absorption at 10,833 Å on the exoplanet WASP-107b reveals that its atmosphere is extended and eroding, and demonstrates a new way to study upper exoplanetary atmospheres.

TL;DR: In this paper, the authors report on six precise spectroscopic Magellan/IMACS observations, five of which target the full optical window from $0.45-0.9
Journal ArticleDOI
Retrieval of planetary and stellar properties in transmission spectroscopy with AURA
TL;DR: In this paper, a new retrieval paradigm for inferring both planetary and stellar properties from a transmission spectrum is presented, where the authors apply their retrieval framework to a sample of hot giant exoplanets to determine the significance of stellar heterogeneity and clouds/hazes in their spectra.
