We present evidence for the impact of a supernova blast-wave on a molecular cloud located inside the Local Bubble, in the area of interaction with the Sco-Cen OB association.
The evidence comes from the analysis of the line of sight toward the nearby (170 pc) star HD102065, located behind the tail of a cometary-shaped, infrared cirrus-cloud which we believe is only 70 pc away from the Sun. The analysis includes numerous transitions of atoms, ions and molecules, in absorption and in emission, in the UV, the optical and the sub-millimeter.
Several peculiar characteristics of the cloud like the spatial structure of its cold phase, the high negative velocities, the high abundance of atoms in excited states and the highly ionized species associated with the highest velocities, as well as the unusually high abundance of small dust particles, are interpreted as the result of the interaction with a supernova shock wave.
This line of sight provides an ideal laboratory to study turbulent flows and mixing layers in the ISM.
