- The mission scientists also will use the light curves to study the stars and their interiors. 开普勒项目科学家还将运用光变曲线研究恒星及其内部结构。
- The gamma-ray bursts (GRB) are the sudden flashes of the hard X/gamma-rays in the sky with very complicated light curves. g射线暴是天空中突然的硬X射线/g射线爆发现象,有着非常复杂的光变曲线。
- We calculate the cross-correlation function (CCF) for the light curves in 25-55 and 110-300 keV bands and derive the spectral lag by fitting the CCF with the Gaussian model. 我们计算了25-55和110-300kev能段的互相关函数(COF),并通过高斯模型拟合CCF得到光谱时滞。
- For four systems (i.e., FG Hya, IK Per, GSC 0619-0232 and V410 Aur), the asymmetric or distorted light curves are fitted fairly well by the dark-spot model. 此外,过相接双星FG Hya的光变曲线还随时间变化,这种变化可能是周期性的磁活动造成的。 结合测光解和分光解,确定了五个双星系统(FG Hya、GR Vir、TV Mus、V410 Aur和XY Boo)的绝对物理参数。

- I groped for the light switch in the dark room. 我在黑暗的房间里摸索着找电灯开关。
- Peak brightnesses in the light curve are known as maxima , while troughs are known as minima . 光度曲线的最高峰处即为 最大值 ,低谷处为 最小值 。
- When a star goes behind another, there will be a reduction of total luminosity. Since the motion of the stars is periodic, the light curve will also be periodic. 当子星经过伴星的前后,由于两星重叠,所以整体亮度会下跌,再加上双星的运动是周期性的,所以光变曲线亦会出现同一周期的变动。
- We use this method to the historical light curve of OJ 287 and find that its main period is 11.9 years, which is in good agreement with the results obtained by other authors. 将此方法用于OJ2 87的历史光变曲线 ;得到其最主要的周期为 11.;9年;与其它结果相符合。
