Supernova 1957D In M83, Supernova Remnants: Ccd Images
Scientific paper
A pilot programme dedicated to studying previously reported extragalactic supernovae of advanced age (> 300 days) has had some early success with observations made at La Silla in April 1989. We report here the detection from direct imaging, and subsequent spectroscopy of the remnant of SN 1957 d in M 83. This galaxy has been a prolific producer of SNe this century (5 so far), and therefore offers a good opportunity for studying evolutionary effects in SNe of different types concentrated in a small area of sky. Unfortunately SN 1957d was not a well observed SN at early phases, and therefore neither the light curve nor the early spectroscopy was available to ensure an unambiguous classification. We now know that many SNe, as they age, develop strong lines of [OI] lambda 6300,63 or strong lines of [OIII] lambda lambda 4959, 5007, and these characteristics facilitate detection by using narrow band filters to image objects in the light of these emission lines. Figure 1 shows the result of imaging of an area of M83 in the light of (a) [OIII] lambda 5007 and (b) a nearby continuum wavelength with EFOSC on the 3.6 m telescope. The arrow points to the position of an object with enhanced brightness in the [OIII] lambda 5007. This object coincides closely with the known reported position of SN 1957d.
