摘要:

我们提出了一个模型来估计产生的同步辐射在微类星体(MQ)喷流由于二次对通过衰变产生的带电π介子质子碰撞恒星风离子和喷流相对论质子。电子/正电子的签名是从一致的粒子能量分布,考虑到由于同步加速器和逆康普顿(IC)过程,以及绝热膨胀的能量损失。探讨了该模型的空间参数和相应的光谱能量分布(SED)。我们的结论是,二次轻子发射代表了一个显着的,但几乎没有占主导地位的贡献,总的无线电发射的质量,与观测结果,可用于测试一些仍然未知的过程中发生在这些对象,以及在其喷流的物质的性质。

英文摘要:

We present a model to estimate the synchrotron radio emission generated in microquasar (MQ) jets due to secondary pairs created via decay of charged pions produced in proton-proton collisions between stellar wind ions and jet relativistic protons. Signatures of electrons/positrons are obtained from consistent particle energy distributions that take into account energy losses due to synchrotron and inverse Compton (IC) processes, as well as adiabatic expansion. The space parameter for the model is explored and the corresponding spectral energy distributions (SEDs) are presented. We conclude that secondary leptonic emission represents a significant though hardly dominant contribution to the total radio emission in MQs, with observational consequences that can be used to test some still unknown processes occurring in these objects as well as the nature of the matter outflowing in their jets.
