BRITEning up the Be Phenomenon
摘要：
对猎户座25的观测大大扩展了用BRITE和SMEI得到的其他早型Be星的图像。两个而不是一个不同的频率规则的可变性：（a）较低的一个，0.0129 c/d，是事件的频率与100-200 mmag的全振幅可能信号质量损失可能由较高的一个，0.1777 c/d驱动。(b)整个功率谱的大部分是组合频率的紧密编织的网络：（i）低于0.25 μ c/d，许多频率是差频。(ii)许多高于2.5 c/d的频率可以表示为和频，在少数情况下可以表示为谐波。(iii)1.1 ~ 1.75 ′，c/d之间的许多频率可描绘为组合频率的亲本。组合频率的数量和分数随着幅度和频率匹配精度的降低而急剧增加。
英文摘要：
Observations of 25 Ori much expand the picture derived of other early-type Be stars with BRITE and SMEI. Two instead of one difference frequencies rule the variability: (a) The lower one, 0.0129 c/d, is the frequency of events with full amplitudes of 100-200 mmag which may signal mass loss possibly driven by the higher one, 0.1777 c/d. (b) Much of the entire power spectrum is a tightly woven network of combination frequencies: (i) Below 0.25\,c/d, numerous frequencies are difference frequencies. (ii) Many frequencies above 2.5 c/d can be represented as sum frequencies and in a few cases as harmonics. (iii) Many frequencies between 1.1 and 1.75\,c/d can be portrayed as parents of combination frequencies. The number and fraction of combination frequencies increases steeply with decreasing amplitude and and accuracy of the frequency matching.
