One of the effects that Universe Sandbox uses to [[Temperature Calculation|calculate]] the temperature of an object is supernova drag heating, which is produced by the friction between the object and any [[Supernova Cloud|supernova clouds]] passing by the object. ==Related Properties & Settings== ===Properties=== * The rate at which energy is added to the object from passing supernova clouds is shown in the [[Gas Drag Power]] property. * The amount of heating depends on the [[Maximum Cloud Radius]] and [[Cloud Mass]] properties of the expanding supernova. * The amount of heating also depends on the object's [[Radius]]. * Supernova drag heating will affect an object's [[Average Temperature]] or [[Surface Temperature]]. ==Models== At every [[N-Body_Simulation#Time_Step|time step]] of a simulation where a [[supernova]] has occurred, Universe Sandbox checks whether any of the [[Supernova Cloud|supernova clouds]] have reached the object. If so, the amount of energy produced by friction is calculated based on the object's size, the supernova cloud's density, and the relative [[Velocity Vector|velocity]] between the object and the cloud. The rate at which energy is added to the object via friction with passing clouds is represented by the [[Gas Drag Power]] property. The Gas Drag Power is included in the [[Energy Absorption Rate]], which is used to calculate the [[Temperature Calculation|change in temperature]] for the object.
