A Stellar Review: Re-Analyzing the Kepler Stellar Radii with Gaia
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.
No dust ring required around Proxima Centauri
What is responsible for the excess radio emission from our nearest star, Proxima Centauri? No alien radio stations required!
Not Quite a Star, Not Quite a Planet: A Planetary-Mass Object in AB Dor
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.
Accidentally Finding a Solar Twin
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.
Something bizarre is happening in stars
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.
