Özet
Optical CCD imaging with Hα and [SII] filters and spectroscopic observations of the galactic supernova remnant G85.9-0.6 have been performed for the first time. The CCD image data are taken with the 1.5 m Russian-Turkish Telescope (RTT150) at TÜBI{dot above}TAK National Observatory (TUG) and spectral data are taken with the Bok 2.3 m telescope on Kitt Peak, AZ.The images are taken with narrow-band interference filters Hα, [SII] and their continuum. [SII]/Hα ratio image is performed. The ratio obtained from [SII]/Hα is found to be ∼0.42, indicating that the remnant interacts with HII regions. G85.9-0.6 shows diffuse-shell morphology. [SII]λλ6716/6731 average flux ratio is calculated from the spectra, and the electron density Ne is obtained to be 395 cm-3. From [OIII]/Hβ ratio, shock velocity has been estimated, pre-shock density of nc=14 cm-3, explosion energy of E=9.2 × 1050 ergs, interstellar extinction of E(B-V)=0.28, and neutral hydrogen column density of N(HI)=1.53 × 1021 cm-2 are reported. © Springer Science+Business Media B.V. 2009.
