Abstract

(Abstract only) In ancient times, people occasionally looked up to find a “nova,” or new star, in the sky. With about thirty-five per year in our galaxy, novae are the most common major stellar explosions. Although researchers now understand what causes a white dwarf to suddenly brighten into a nova, many puzzles remain, such as why novae appear to eject orders of magnitude more material than predicted by theory, and how a uniform eruption on a spherical white dwarf can expel matter in the form of jets, clumps, and rings. Coordinated observations at radio, optical, and X-ray wavelengths can answer these questions. I will describe a new opportunity for amateur astronomers to work with professional astronomers who are using X-ray and newly upgraded radio telescopes to observe novae. Participants will have the opportunity to learn about novae, share their own expertise, and participate in the process of scientific discovery.
