标题： Fireball Models for Flares in AE Aquarii

摘要： 我们研究了灾变变星AE~Aqr在该系统的“磁力螺旋桨”模型背景下的爆发行为。 爆发被认为是由于系统中高速旋转的白矮星磁层相互作用后喷出的物质中的高密度区域之间的碰撞产生的。 我们计算了爆发的第一个定量模型，并从由此产生的高温、膨胀的气体球中计算出随时间变化的发射光学光谱。 我们在不同假设下将结果与观测进行比较，并推导出参与爆发的物质的质量、尺度和温度值。 我们发现拟合结果表明该系统中的次级恒星具有第二星族成分。 显示英文摘要

摘要： We examine the flaring behaviour of the cataclysmic variable AE~Aqr in the context of the `magnetic propeller' model for this system. The flares are thought to arise from collisions between high density regions in the material expelled from the system after interaction with the rapidly rotating magnetosphere of the white dwarf. We calculate the first quantitative models for the flaring and calculate the time-dependent emergent optical spectra from the resulting hot, expanding ball of gas. We compare the results under different assumptions to observations and derive values for the mass, lengthscale and temperature of the material involved in the flare. We see that the fits suggest that the secondary star in this system has Population II composition.
