Temperature and cooling rate data for a conductively cooling 250km radius planetesimal with and without temperature-dependent material properties (NERC Grant NE/L002574/1)

The data contain the results of model of a conductively cooling planetesimal with a radius of 250 km and a core radius of 125 km. Two data files are included: one for a model run which uses constant values for thermal properties (conductivity, heat capacity, and density) while the second uses temperature-dependent functions for these properties. Further details of the model in Murphy Quinlan et al., (in prep). Four arrays are included in each of the compressed data files: mantle temperature array; core temperature array; mantle cooling-rate array; core cooling-rate array. All arrays are the same size (125 by 126229) and hold data for radii values through time, with a radius-step of 1 km and time-step of 1E11 seconds over a total time period of 400 Myr.

Statement: The arrays are the output of a numerical model that solves the conduction equation using an explicit finite difference scheme, FTCS (Forward-Time Central-Space) which gives first-order convergence in time and second-order in space. The radius-step was 1 km and time-step was 1E11 seconds. The arrays contain results up to 400 Myr.
