Biography

Frederick Walter is a galactic astronomer. His research interests include novae, neutron stars, Solar and stellar activity (flares and coronal mass ejections, and their effects on the Earth), and the formation of sun-like and low mass stars, brown dwarfs, and exoplanets. He has been consulted about Mars and Pluto. He observes regularly, using observatories in Chile and Arizona, and is a guest investigator on the Hubble Space Telescope and the Chandra and XMM-Newton X-ray observatories.
