宽多重系统中的冷矮星:论文I:在一个松散约束的共同自行对中的两个中M矮星

Cool dwarfs in wide multiple systems: Paper I: Two mid-M dwarfs in a loosely-bound common-proper-motion pair

Jose A. Caballero

摘要:

这是第一个一系列的作品致力于调查冷矮星在广泛的多系统。在这里,我介绍了Koenigstuhl 4 A和B,两个明亮的中间M矮星,具有共同的高自行,相隔299弧秒。在系统的最可能距离19 pc,预计物理距离为5700 AU,这使得Koenigstuhl 4 AB成为迄今为止发现的具有晚型组件的最小边界双星系统之一。我还第一次将主要与ROSAT X射线源联系起来。

英文摘要:

This is the first of a series of works devoted to investigate cool dwarfs in wide multiple systems. Here, I present Koenigstuhl 4 A and B, two bright, intermediate M dwarfs with a common high proper-motion and separated by 299 arcsec. At the most probable distance of the system, 19 pc, the projected physical separation is 5700 AU, which makes Koenigstuhl 4 AB to be one of the least bound binary systems with late-type components found to date. I also associate the primary with a ROSAT X-ray source for the first time.
