Could the Local Cavity be an Irregularly Shaped Strömgren Sphere?

Extending for 50–200 pc in all directions from the Sun, the Local Cavity has been characterized as an old supernova bubble consisting of low-density million-degree plasma heated by supernova shocks. We summarize the arguments for and against this model and conclude that hydrogen in the Local Cavity...
