Exoplanets can be detected through transits from "summary" of Exoplanets and Alien Solar Systems by Tahir Yaqoob
One effective method for detecting exoplanets is through transits. When a planet passes in front of its parent star from our perspective, it causes a temporary decrease in the star's brightness. This phenomenon is known as a transit and can be observed by telescopes on Earth or in space. By carefully monitoring the light curve of a star over time, scientists can identify these periodic dips in brightness and infer the presence of an exoplanet. Transits offer valuable information about exoplanets, such as their size, orbital period, and distance from their star. The depth and duration of a transit can reveal the size of the planet relative to its star and provide clues about its composition. Additionally, repeated transits allow scientists to calculate the exoplanet's orbital period and distance from its star, which are crucial factors in determining its habitability. One c...
