英文摘要 | High-dispersion, high-S/N spectroscopic observations of SN 2002ap in M 74 were carried out in the wavelength range of 4120-6860 Angstrom using the High Dispersion Spectrograph of the Subaru Telescope. Neither emission nor absorption features relating to SN 2002ap itself were identified in the high-dispersion echelle spectrum, but a pair of Na I D1 and D2 absorption lines were detected at a redshift corresponding to the disk of M 74, and each was found to show three components. The column densities of these components are log N(NaI) = 11.47, 10.47, and 10.72 for the first, second, and third components, respectively. The interstellar reddening in M 74 was estimated from these components, and was combined with that in the Galaxy to yield a total value of E(B - V) = 0.09 +/- 0.01 along the line of sight to SN 2002ap. |
