Detection of optical emission in the area of G127.1+0.5.
Abstract
Diffuse optical emission has been detected around the area of the galactic SNR G127.1+0.5 for the first time. Deep H-alpha CCD images have been used to identify the nebulosity that correlates with both the IR emission evident on the IRAS maps and the radio contours of the galactic remnant G127.1+0.5. The optical filaments of the known nearby remnant G 126.2+1.6 have also been observed in order to evaluate the detection ability of our instrumental set-up. The intensity of the optical emission from the nebulosity has been determined by comparison with the standard star BD +28 deg 4211. The detection of the diffuse optical emission is established beyond doubt. The structure of the surrounding area is discussed and an attempt is made to identify the origin of the detected emission by studying this area at other wavelengths.
