Abstract

Advances in technology and instrumentation have now opened up virtually the entire radio spectrum to the study of stars. An international workshop "Radio Stars: from kHz to THz" was held at the Massachusetts Institute of Technology Haystack Observatory on 2017 November 1-3 to enable the discussion of progress in solar and stellar astrophysics enabled by radio wavelength observations. Topics covered included the Sun as a radio star, radio emission from hot and cool stars (from the pre- to post-main-sequence), ultracool dwarfs, stellar activity, stellar winds and mass loss, planetary nebulae, cataclysmic variables, classical novae, and the role of radio stars in understanding the Milky Way. This article summarizes meeting highlights along with some contextual background information.
