In the optical spectra of some young supernova remnants,Balmer line is often observed to have two components:a broad component produced by charge exchange between cold neutral atoms and high energy protons,and a narrow component produced mainly by collisional excitation of preshock cold neutral atoms.
但是,近来更细致的观测和理论计算表明,超新星遗迹中Balmer发射线的双线结构很可能还要受到其他因素的影响,并且与激波速度和电子-质子的热平衡有着密切的关系。
SS433 is a famous high energy source in our Galaxy, W50 is the supernova remnant surrounding it.
SS433是银河系内一个著名的高能天体,W50是它周围的超新星遗迹,自20世纪70年代末SS433的运动模型建立以来,已经受到了越来越多的关注,取得了丰富的多波段观测资料。
