Jason Dittmann

Postdoctoral Fellow

Jason Dittmann believes that forming a deep understanding of new worlds requires that we first understand their host stars. Through his work, Jason overcomes barriers to understanding nearby stars to better characterize their physical attributes and detect the new worlds orbiting them. His research focuses on small and cool stars, which are the most abundant type in the Milky Way Galaxy and often the best targets when searching for habitable exoplanets. Jason makes use of parallax techniques—applying multiple viewpoints to measure the distances to 1600 nearby stars, and then using these measurements to accurately determine the physical attributes of these stars and of the planets that may orbit them. He found that these small stars are similar in composition to our Sun, lending an important clue to what makes a star likely to have a planetary companion. MORE
