标题： Was an Outburst of Aquila X-1 a Magnetic Flare?

摘要： 我指出在2009年11月X射线双星天鹰座X-1的爆发期间，射电和软X射线光曲线之间存在一个有趣的相似性，这与一些太阳耀斑类似。 在那次爆发中，天鹰座X-1的软X射线和射电光度比也与一些弱太阳耀斑类似，而且8 GHz附近的射电谱也是如此。 基于这些观察，以及一些最近的研究指出吸积盘日冕和恒星耀斑的一些类似特性，例如射电与X射线光度比（Laor & Behar 2008），我推测天鹰座X-1的软X射线爆发可能与其盘日冕的巨大磁耀斑有关。 显示英文摘要

摘要： I point to an interesting similarity in the radio and the soft X-ray light curves between the November 2009 outburst of the X-ray binary Aquila X-1 and some solar flares. The ratio of the soft X-ray and radio luminosities of Aquila X-1 in that outburst is also similar to some weak solar flares, and so is the radio spectrum near 8 GHz. Based on these, as well as on some other recent studies that point to some similar properties of accretion disk coronae and stellar flares, such as ratio of radio to X-ray luminosities (Laor & Behar 2008), I speculate that the soft X-ray outburst of Aquila X-1 was related to a huge magnetic flare from its disk corona.
