Evaporating exoplanet WASP-69b solves two planetary puzzles

<p>The first successful methods for finding exoplanets involved measuring the light from a parent star very exquisitely. If there are planets orbiting the star in question, the star isn&rsquo;t only going to gravitationally pull on that planet, but the planet will gravitationally pull on the star, causing the star to move in an elliptical pattern around the mutual center-of-mass of the star-planet system. That causes the star to appear to &ldquo;wobble&rdquo; with respect to us, as it will periodically move towards-and-away from us leading to its light redshifting and blueshifting in a periodic fashion. This detection method, known as either the radial&hellip;</p> <p><a href="https://medium.com/starts-with-a-bang/evaporating-exoplanet-wasp-69b-solves-two-planetary-puzzles-3f8e843b5a2c"><strong>Learn More</strong></a></p>
