The circumstellar environment around the extreme Galactic red supergiant NML Cygni: Dense, dusty, and asymmetric
E. De Beck, H. Andrews, G. Quintana-Lacaci +1
Supernova observations imply the presence of a dense and asymmetric circumstellar environment around SN Type II progenitors, whereas the mass loss from these progenitors, namely, r…
