Description
The authors examine, using K I and Na I absorptions, a generally conical volume out to some 200 pc from the Sun placing constraints on a number of the individual interstellar cold clouds. Using the hypothesis of pressure confinement, they find temperatures in these clouds of ≡70K; typical cloud masses range up to a few hundred solar masses. The authors also show that the mass fraction of the LISM in these cold clouds is high, at least 80% of the total, while the filling factor is low, well below 10% of the total LISM volume.
