A Search for Planetary Metastable Helium Absorption in the V1298 Tau System

Shreyas Vissapragada, Guðmundur Stefánsson, Michael Greklek-McKeon +28

Early in their lives, planets endure extreme amounts of ionizing radiation from their host stars. For planets with primordial hydrogen and helium-rich envelopes, this can lead to s…

The Stellar Variability Noise Floor for Transiting Exoplanet Photometry with PLATO

Brett M. Morris, Monica G. Bobra, Eric Agol +2

One of the main science motivations for the ESA PLAnetary Transit and Oscillations (PLATO) mission is to measure exoplanet transit radii with 3% precision. In addition to flares an…
