The Reciprocal Transit C. Scharf (2019)

Since the first detected exoplanetary transit in 1999, use of this technique of looking for tiny dips in light as planets pass in front of their parent stars has surged. On paper it is simplicity itself, in practice it requires exquisite precision in measuring the brightness of stars, along with a deep knowledge of the intrinsic behavior of stellar photospheres (the outer layer of stars where the majority of light is emitted), orbital mechanics, and statistical techniques for eking out detections and characterizations of other worlds.
