During a phase of planet formation, planetary embryos interact, collide, and/or combine to form the surviving planets we know and love. Simulating this phase is computationally challenging, but could machine learning help out?
TESS was designed to find transiting planets. Today’s authors use TESS to search for free-floating planets via gravitational lensing and find a candidate event.
Close-in planets are expected to have shrinking orbits. Catching a planet decay on its way to the warm embrace of its star is however impressively difficult.
Everyone wants to find a habitable planet. The authors of today’s paper make a compelling case that the HR 5183 system is not the best place to look.
