Recent advances in computational methods and high-performance computing have given rise to increasingly complex models of star formation, with simulations now able a variety of physical phenomena across a vast range of scales.
Much interest has been paid to effects of feedback processes in star-forming systems. In particular, the roles of radiation pressure from massive stars and kinetic feedback from outflows have begun to be explored in some detail. By comparison, the effects of thermal feedback have remained relatively obscure, partly due to the dominance of other mechanisms in many systems of interest, but also due to a lack of reliable methods with which to model them.
In this talk, I will give a brief overview of the main issues in attempting to simulate stellar heating in star formation calculations, and give an update on recent progress towards implementing a sub-grid model for calculating accretion feedback in the sphNG code.
