Narrow features in the early spectrum of SN 1993J.

BENETTI S., PATAT F., TURATTO M., CONTARINI G., GRATTON R. and CAPPELLARO E.

Abstract (from CDS):

High resolution spectra of SN 1993J obtained on March 31.0, only three days past outburst, show narrow emission lines due to Hα, HeII λ4686 and to the high ionization [FeX]λ6374 and [FeXIV]λ5303. The latter, to our knowledge, has never been identified before in SN spectra. The FWHM of the recombination lines indicates that the emitting gas has velocities ∼170km/s which seems too large to be attributed to a normal stellar wind. The detection of narrow lines soon after outburst and their disappearance one week later, indicate that the circumstellar gas is confined close to the exploding star (R≤4x1015cm). The coronal lines are probably generated in the CSM heated by the radiation emerging from the shocked regions. A kinetic temperature of ∼2.5x106K is derived from the line widths. The interstellar NaID absorption shows a multiple component structure in agreement with previous reports. Its equivalent width suggests a moderately high reddening, 0.2≤E(B-V)=<0.8 wheras the upper limits to the 5780A and 5797A DIBs indicates a reddening E(B-V)=<0.4

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
