Solutions are developed for isothermal, mass-limited rarefactions in which the temperature is held constant by continued heating. The case of spatially constant temperature and fixed total energy is also revisited. These solutions are useful in the context of experiments in which plasmas are continuously heated for long periods (up to tens of ns) by present-day lasers or hohlraums.
