摘要

我回顾了恒星形成背景下的恒星反馈数值模拟的现状，从单个恒星的形成到包括宇宙再电离在内的星系形成模型。我调查了最近开发的大量算法来解决辐射传输问题和模拟恒星风、超新星和原恒星喷流。我将讨论这些模拟的结果，包括分子云中的恒星形成，不同反馈机制之间的相互作用以及与磁场的相互作用，以及在银河系和宇宙尺度模拟的更广泛背景下的模拟。

The modelling of feedback in star formation simulations

I review the current state of numerical simulations of stellar feedback in the context of star formation at scales ranging from the formation of individual stars to models of galaxy formation including cosmic reionisation. I survey the wealth of algorithms developed recently to solve the radiative transfer problem and to simulate stellar winds, supernovae and protostellar jets. I discuss the results of these simulations with regard to star formation in molecular clouds, the interaction of different feedback mechanisms with each other and with magnetic fields, and in the wider context of galactic- and cosmological-scale simulations.
