夸克星的韧致辐射
Bremsstrahlung emission from quark stars
摘要:
数值计算了裸夸克星表面电子-电子韧致辐射的发射率和表面通量。由于有效光子质量的存在,电子相空间受到限制,导致强抑制。的发射率和表面通量被发现是大大小于在以前的工作中发现的,电子-正电子对生产的点将仍然是在相对论制度的所有温度下的主导机制。因此,即使在低表面温度下,电子对的产生仍然是一个主导过程,正如Usov在arXiv:astro-ph/9712304中最初提出的那样。
英文摘要:
We calculate numerically the emissivity and surface flux of electron-electron bremsstrahlung radiation from the surface of a bare quark star. The restricted electronic phase space due to the presence of an effective photon mass results in a strong suppression. The emissivity and surface flux are found to be substantially smaller than those found in previous work, to the point where electron-positron pair production would remain the dominant mechanism at all temperatures in the relativistic regime. As a consequence, pair production remains a dominant process even at low surface temperatures as originally suggested by Usov in arXiv:astro-ph/9712304.
