天蝎座V 393：双周期变星的另一个线索
The interacting binary V 393 Scorpii: another clue for Double Periodic Variables
摘要：
本文简要报道了天蝎座V393的光谱性质. He I 5875的H α发射、形状和径向速度都受到长周期的调制。长周期被解释为一个弛豫周期的circumprimary光盘，累积的质量转移从捐助者，直到某些不稳定性产生光盘耗尽。
英文摘要：
We give a brief report on spectroscopic properties of V 393 Scorpii. H alfa emission and shape and radial velocity of He I 5875 are modulated with the long cycle. The long cycle is explained as a relaxation cycle in the circumprimary disc, that cumulates the mass transferred from the donor until certain instability produces disc depletion.
