Answer:

The luminosity of both the stars is same star A is closer to the planet Earth as compared to star B.

Explanation:

From the mentioned case we can infer that the most accurate relation between the stars and the astronomer on earth observing for over a period is that the luminosity of the stars is same.

The more drawn out the pulsation time frame, the more brilliant the star. The period-luminosity connection for old style Cepheid was found in 1908 by Henrietta Swan Leavitt in an examination of thousands of different stars in the Magellanic Clouds.
