    "abstract": "New solutions are found for the non-relativistic hydrodynamical equations.\nThese solutions describe expanding matter with a Gaussian density profile. In\nthe simplest case, thermal equilibrium is maintained without any interaction,\nthe energy is conserved, and the process is isentropic. More general solutions\nare also obtained that describe explosions driven by heat production, or\ncontraction of the matter caused by energy loss.",
