Radio Stars: From kHz to THz

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 discuss the 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.
