Abstract:
A program of high resolution spectroscopy of comets is being conducted
at TNG (Canary Islands) using the echelle spectrograph SARG. The aim
of the program is to catalogue emission lines in the visible range of
various comets, compare them and possibly identify the many existing
unknown lines. As a first step, we catalogued the lines in the
spectrum of the comet 153P/Ikeya-Zhang and compared them with the
lines already listed in existing catalogues. The comet was observed
with SARG on the night 19-20 of April, 2002, with a short slit
covering the spectral range of 4620-7920Å and with a resolving
power R=57000, finding 8468 emission lines.
Description:
Catalog of emission lines of comet 153P/Ikeya-Zhang, obtained from a
spectrum in the visible spectral range 4620-7920 Angstrom. The comet
was observed on the night 19-20 April 2002 with the TNG telescope and
the SARG echelle spectrograph using the slit 0.8x5.3 arcsecs providing
a resolving power of 57000. The identification of the emissions was
based on the catalog and the context plots of Cochran & Cochran
(2002Icar..157..297C 2002Icar..157..297C). In addition to the table we have prepared 28
plots of the 55 echelle orders showing all the emission lines
catalogued. Each plot name is composed by the initials of the comet
name (iz) and the number of the two orders plotted.
