Radio Stars in the Era of New Observatories

An international conference Radio Stars in the Era of New Observatories was held at the Massachusetts Institute of Technology Haystack Observatory on 2024 April 17-19. The conference brought together more than 60 researchers from around the world, united by an interest in using radio wavelength observations to explore the physical processes that operate in stars (including the Sun), how stars evolve and interact with their environments, and the role of radio stars as probes of our Galaxy. Topics discussed at the meeting included radio emission from cool and ultracool dwarfs, extrasolar space weather, stellar masers, thermal radio emission from evolved stars, circumstellar chemistry, low frequency observations of the Sun, radio emission from hot stars, applications of very long baseline interferometry techniques to stellar astrophysics, stellar explosive events, the detection of radio stars in the latest generation of widefield sky surveys, the importance of radio stars for understanding the structure and evolution of the Milky Way, and the anticipated applications for stellar astrophysics of future radio observatories on the ground and in space. This article summarizes research topics and results featured at the conference, along with some background and contextual information. It also highlights key outstanding questions in stellar astrophysics where new insights are anticipated from the next generation of observational facilities operating at meter through submillimeter wavelengths.
