X-ray Detection of SN1994W in NGC 4041?

Abstract

Optical spectra of SN1994W in NGC 4041 revealed the presence of a dense (N_e > 10^8 cm^-3) circumstellar shell. An observation with the ROSAT HRI detected a source, with a 0.2-2.4 keV luminosity of ~8x10^39 erg/sec, coincident with the position of SN1994W to within 1''.4. The positional coincidence plus the optical evidence for a dense circumstellar shell support the identification of the X-ray source as SN1994W.
