Astronomy and exoplanet science are entering into an era of unprecedented precision. Check out Dr. Keivan Stassun’s plenary talk at #AAS232 to learn more!
Using new Gaia data, the authors update the stellar radii for the majority of Kepler’s stars. While they find that most stars have similar radii to previous reported values, there are some large discrepancies.
What is responsible for the excess radio emission from our nearest star, Proxima Centauri? No alien radio stations required!
In or out? Today’s paper explores whether or not an unusual object belongs to the AB Doradus moving group—and what it means if it does.
After accidentally observing the wrong star this paper’s authors discovered a previously-unknown solar twin, a type of star which can help shed light on a number of questions in astronomy.
The light from a star is not constant, it varies as the layers of hot material move back and forth, clump and disperse. Most of these vibrations are visible, detectable, and well understood. But some bizarre new vibration is happening in stars, for which we have no clear path to an explanation.
