论文摘要
富里型恒星的光度爆发,其大小为$ \ sim100 l _ {\ odot} $,并且持续了数十年,可能会影响周围原磁性磁盘的化学组成。使用星体化学模型,我们分析了爆发引起的变化,并寻找对亮度升高敏感的物种。磁盘分子组成的某些变化不仅出现在爆发本身中,而且在爆发结束后数十年也可以保留。我们分析了负责这些影响的主要化学过程,并评估化学惰性物种恢复到前爆发丰度的时间表。
Luminosity outbursts of the FUOri type stars, which have a magnitude of $\sim100 L_{\odot}$ and last for decades, may affect chemical composition of the surrounding protoplanetary disk. Using astrochemical modeling we analyze the changes induced by the outburst and search for species sensitive to the luminosity rise. Some changes in the disk molecular composition appear not only during the outburst itself but can also retain for decades after the end of the outburst. We analyze main chemical processes responsible for these effects and assess timescales at which chemically inert species return to the pre-outburst abundances.
