Swift Observations of Proxima Cen
Abstract
Swift observed Proxima Cen (dM5.5e) for more than 40 segments (roughly 100 separate exposures) from 2009 to 2012, including several UV grism observations. We present analyses of variability in the optical, UV, and X-ray bands on time scales covering individual flares to a possible multiyear stellar cycle, and show moderate-resolution spectra covering 2300-6000 Angstroms.
