Abstract

Optical spectra of faint emission along the northern limb of Kepler's supernova remnant (SN 1604) show only H-alpha and H-beta line emissions over the spectral range 4700-7000 A. The detected H-alpha emission consists of a broad component and a narrow, unresolved component. The observational data suggests the presence of Balmer-dominated, or nonradiative, emission associated with the remnant's high-velocity shocks. Nonradiative shock models are used to interpret the width of the broad component and the flux ratio of the broad to narrow components. The shock velocity is estimated at 1670-2800 km/s. 29 refs.
