"Model Reveals Impact of Star's Brightness on Exoplanet Sizes"

New model calculations show that the brightness distribution of a star's limb, influenced by its magnetic field, affects the shape of the light curve and the interpretation of exoplanet data. Researchers demonstrate that including the star's magnetic field in model calculations resolves discrepancies between observational data and previous models, providing a more accurate analysis of exoplanet atmospheres. This study offers a way to improve the interpretation of data from space telescopes like the James Webb Space Telescope and suggests the potential for inferring stellar magnetic field strength from exoplanet observations.
