The first detection of an inverse Rossiter-McLaughlin effect
How do you observe an Earth transit, from Earth? You use some of the Solar System’s largest mirrors. The authors did. They found an anomaly.
Strange Inclinations: A Unique Multiplanet System
Our Solar System is pretty straightforward. Roughly speaking, all the planets orbit in the same plane, most spin on their axes in the same direction in that plane, and even the Sun rotates in a manner consistent with all this. The small, rocky planets are closer to the Sun, and the big, gaseous planets are farther from the Sun. Simple. Now that we are finding planets orbiting other stars, many are turning out to be multiplanet systems like our own Solar System.
A New Explanation for Spin-Orbit Misalignment In Planetary Systems?
This work presents an interesting new idea to explain the apparent misalignment between the rotation of stars and the orbits of their planets.
