Abstract The origin of the local interstellar matter, especially the hot component, is studied. The bulk of the local interstellar space is occupied with hot low-density matter, which is similar to the gas heated by the shock front of the supernova remnant. We investigate the model that our Sun is located in a superbubble. The superbubbles are observed in Orion-Eridanus region and Gum nebula. The similar objects are found in λ 21 cm H I maps as H I shells and holes. The superbubbles certainly correlate with OB associations and giant molecular clouds. The evolution of superbubbles formed by sequential supernova explosions in an OB association is studied by hydrodynamical simulations. We compare the results with observations. A model of cycling of interstellar matter is presented, in relation to the evolution of the superbubble.
