light curve

noun

, Astronomy.

First recorded in 1885–90

Such a diagram is called the star's light curve, and we may read from it that at any time between 5h.

The lower curve is the light-curve of the star during a period of 7.167 days.

Thus we have valuable evidence in confirmation of the correctness of the conclusions drawn from the light-curve.

Thus the light curve and the spectroscopic velocity curve are very similar in shape, but one is like the other turned upside down.

These last are all to be determined from the nature of the light-curve.
