概要
- 論文の詳細を見る
Shell motion in the expanding universe is investigated using a simple solution, which is derived from the momentum conservation under the effect of gravity and energy-input. A similarity solution is given for the constant energy-input case. For the explosion without a continuous energy-input, partition of energy between kinetic and gravitational energies is discussed. The blast wave expansion due to an activity of galactic objects in the early universe is discussed.
