在Ariel V对蟹状星云的常规观测中,实验A,旋转调制准直器(RMC),发现了一个新的x射线源A0535+26。在4月13日的第一次观测中,光源才被探测到,在16天的观测中,它的亮度几乎是蟹状星云强度的两倍(在3-7 keV范围内)。光源周期性变化,周期为104 s,在3-7 keV范围内具有非常平坦的频谱。
DURING routine observations of the Crab Nebula by Ariel V, experiment A, the rotation modulation collimator (RMC), discovered a new X-ray source A0535+26. The source was just detectable during the first observation on April 13, and during the 16 d of observation was seen to brighten to nearly twice the Crab's intensity (in the 3–7 keV range). The source varies periodically, with a period of 104 s, and has a very flat spectrum in the 3–7 keV range.
