The dumpler technique is most sensitive to planets in the plane of where we're looking, but maybe not quite as sensitive imean. If they were a little bit out perfect aliment, ou counld still maybe get a dobler shift. The trick is that you can also change that signal by changing the mass of the planet. And if i make the planet more massive, then i move to make the star move more.

Recent years have seen a revolution in the study of exoplanets, planets that orbit stars other than the Sun (or don’t orbit stars at all). After a few tentative detections in the 1990s, dedicated instruments in the 2000s have now pushed the number of known exoplanets into the thousands, enough to begin to categorize their distribution and properties. Today’s guest is John Asher Johnson, one of the leaders in this field. We talk about the various different ways that exoplanets can be detected, what we know about them know, and what might happen in the future.
