CO Observations of the Type Ia Supernova Remnant 3C 397 by the Nobeyama 45 m Radio Telescope: Possible Evidence for the Single-degenerated Explosion

We present a new CO observation toward the Type Ia supernova remnant 3C 397 using the Nobeyama 45 m radio telescope at an unprecedented angular resolution of  ∼18″. We newly found that the CO cloud at V LSR = 55.7–62.2 km s −1 (60 km s −1 cloud) shows a good spatial correspondence with the radio con...
