It is often assumed that mixed-morphology (MM) SNRs evolve in very dense environments, and that their centre-filled X-ray morphology is due to interactions between the SNRs and their surroundings. We aim to determine whether MMSNR VRO 42.05.01 is embedded in, and interacting with, a dense molecular environment. We used the IRAM telescope in Pico Veleta, Spain, to search for interaction between the SNR and neighbouring molecular clouds.
