在有限的,相对论的,热等离子体的过程和平衡进行了研究,考虑到电子-正电子的产生和湮灭,光子产生的内部过程,光子产生的磁场。后者的加入扩展了先前对这类等离子体的研究。分析了热同步辐射、复合同步辐射的基本关系,包括无复合辐射的发射和吸收、复合热同步辐射、复合同步辐射和轫致辐射光度。计算了偶平衡,包括近似值和无量纲参数,偶平衡方程,最高温度和场强,以及个别模型和冷却曲线。
Processes and equilibria in finite, relativistic, thermal plasmas are investigated, taking into account electron-positron creation and annihilation, photon production by internal processes, and photon production by a magnetic field. Inclusion of the latter extends previous work on such plasmas. The basic relations for thermal, Comptonized synchrotron emission are analyzed, including emission and absorption without Comptonization, Comptonized thermal synchrotron emission, and the Comptonized synchrotron and bremsstrahlung luminosities. Pair equilibria are calculated, including approximations and dimensionless parameters, the pair balance equation, maximum temperatures and field strengths, and individual models and cooling curves.
