论文摘要
使用一维恒星演化代码,我们模拟了红色超级巨星(RSG)恒星对注入能量和批量去除的响应。我们采用我们注入的能量的值以及根据先前的三维流体动力学模拟(NS)在高度偏心轨道上进行的三维流体动力学模拟,该轨道进入了RSG恒星的封装半年,并通过积分磁盘吸收质量。我们发现,对于〜1E47-1E48 ERG的注入能量,去除〜0.03-0.6mo的质量,RSG包膜扩展到大半径。因此,我们预计NS将继续在这个大规模膨胀的信封内绕过几个月,最初是最初的RSG半径的两倍,将继续吸收质量并发射喷气机长时间。尽管这些后期喷气机比NS发射的喷气机更弱,而在原始的RSG信封内部,但后期喷气机实际上可能对光曲线更具影响力,导致长时间,几个月到几年,明亮,大约是10^8lo的瞬态事件。大约十年后,RSG或多或少地返回放松的结构,因此在NS的下一个Periastron通道中可能发生另一个短暂事件。我们的结果增加了已经有很多令人困惑的瞬态事件的各种喷气驱动爆炸/爆发。
Using a one-dimensional stellar evolution code we simulate the response of a red supergiant (RSG) star to injection of energy and to mass removal. We take the values of the energy that we inject and the mass that we remove according to our previous three-dimensional hydrodynamical simulations of a neutron star (NS) on a highly eccentric orbit that enters the envelope of an RSG star for half a year and launches jets as it accretes mass via an accretion disk. We find that for injected energies of ~1e47-1e48 erg and removed mass of ~0.03-0.6Mo the RSG envelope expands to a large radius. Therefore, we expect the NS to continue to orbit inside this massive inflated envelope for several more months, up to about twice the initial RSG radius, to continue to accrete mass and launch jets for a prolonged period. Although these late jets are weaker than the jets that the NS launches while inside the original RSG envelope, the late jets might actually be more influential on the light curve, leading to a long, several months to few years, and bright, about >10^8Lo, transient event. The RSG returns to more or less a relaxed structure after about ten years, and so another transient event might occur in the next periastron passage of the NS. Our results add to the already rich variety of jet-driven explosions/outbursts that might account for many puzzling transient events.
