磁活动,magnetic activity
1)magnetic activity磁活动
1.Since RS CVn-type binary was defined by Hall in 1976, the solar-type activity(" chromospheric activity" or "magnetic activity") of contact binaries interests many astronomic researchers.自从1976年，Hall明确地提出RS CVn型双星的定义以来，密近双星的类太阳活动(也叫“色球活动”或“磁活动”)性质就引起众多天文工作者的极大兴趣。
2.Under this extreme physical conditions, RS CVn-type binaries show all features of solar activity: chromospheric emission lines (such as Hα, Hβ, CaII H&K), X-ray emission, spots, flare, mass loss due to star wind,magnetic activity, and orbital period variations.在这种极端物理条件下,RS CVn型双星表现出了许多类似太阳的磁活动现象:色球活动(如Hα,Hβ,CaII H&K等谱线发射)、X射线发射、大面积的黑子活动、耀斑、星风损失以及轨道周期变化。
