The youngest stars in the galactic region surrounding around the Solar Neighborhood are associated with «subgroup B1» of the Pleiades (M 45) stellar moving group, and astronomers hypothesize that the more massive stars born in this group may have already exploded as 20 or so supernovae over the past 10 to 20 million years as the entire group of stars moved through a nearby region of the Local Bubble (Berghoefer and Breitschwerdt, 2002).

Assuming that the Local Bubble or Chimney was created by the supernovae of young, massive stars during the past few million years, some astronomers have been looking for their probable source among the 27 member B stars of the Pleiades moving group, which are located towards the nearest part of Gould's Belt of massive hot, OB - type stars (more discussion in pdf).
