Origin of the Local Bubble

Breitschwerdt, Dieter; de Avillez, Miguel A.; Fuchs, Burkhard +1 more

We present a new unbiased search for OB associations in the Solar neighbourhood which have hosted the progenitor stars of the core collapse supernovae responsible for the Local Bubble in the interstellar gas. For this purpose we have analyzed a volume complete set (with a diameter of 400 pc) of B stars drawn from the Hipparcos catalogue and the Ar…

What Physical Processes Drive the Interstellar Medium in the Local Bubble?

Dettbarn, C.; Breitschwerdt, D.; Fuchs, B. +1 more

Recent 3D high-resolution simulations of the interstellar medium in a star forming galaxy like the Milky Way show that supernova explosions are the main driver of the structure and evolution of the gas. Its physical state is largely controlled by turbulence due to the high Reynolds numbers of the average flows. For a constant supernova rate a dyna…
