The circumstellar medium of the peculiar supernova SN1997ab
We report the detection of the slow-moving wind into which the compact supernova remnant SN 1997ab is expanding. Echelle spectroscopy provides clear evidence for a well-resolved narrow (full width at zero intensity, FWZI ~180 km s^-1) P Cygni profile, both in Hα and Hβ, superimposed on the broad emission lines of this compact supernova remnant
