Stellar Imager (SI): developing and testing a predictive dynamo model for the Sun by imaging other stars

The StellarImager mission concept is a space-based UV/Optical interferometer designed to resolve surface magnetic activity and subsurface structure and flows of a population of Sun-like stars, in order to accelerate the development and validation of a predictive dynamomodel for the Sun and enable accurate long-term forecasting of solar/ stellarmagnetic activity.
