球形喷出物以超相对论速度膨胀进入星周物质的早期演化

Early evolution of spherical ejecta expanding into the circumstellar matter at ultra-relativistic speeds

Toshikazu Shigeyama, Akihiro Suzuki, Ko Nakamura

摘要:

我们提出了一个新的自相似解,描述了由同源膨胀的球形喷出物与星周物质碰撞产生的超相对论流的早期演化,其中激波在星周物质中传播,而弱间断以声速在喷出物中传播

英文摘要:

We present a new self-similar solution describing early evolution of an ultra-relativistic flow resulting from a collision of homologously expanding spherical ejecta with the circumstellar matter, in which a shock wave propagates in the circumstellar matter while a weak discontinuity propagates in the ejecta at the sound speed
