Document Summary
Involves measuring the wobble of a star produced by the gravitational pull of a large. The star & planet orbit around a shared center of mass, causing the star to wobble . As a star moves to & from earth due to the wobble , the frequency of light emitted is. Precise measurement of this small change in frequency allows the orbits of the star & planet to be deduced, which provides info on the size of the planet & its distance from the star. Giant planets that orbit very close to their stars. The degree of reduction is a function of planet size, & the periodicity w/ which it. Measures the drop in luminosity that results as a planet passes in their star & spiraled inward front of a star, blocking part of its light occurs is a function of orbital period, & therefore distance. Designed to continuously measure the brightness of over 145,000 stars, looking for.
