IUE and Optical Spectra of RZ LMI and ER UMa Throughout their 19 and 43 Day Cycles

Abstract

Abstract. IUE and optical data were obtained throughout the supercycles of RZ LMi and ER UMa during 1993/94. While most of the spectral and photometric characteristics are consistent with disk changes in systems with a relatively high accretion rate and low inclination, the cause of the high accretion rate in this subset of SU UMa stars is not known.
