The loudest planets in our sky: gravitational waves from Super-Jupiters
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
More Informative Mapping of Exoplanetary Peekaboos
Mapping the atmospheres and surfaces of exoplanets is ailed by degeneracies due to the choice of map structure and orbital parameter uncertainties. Today’s paper attempts to solve this by using a principal component analysis approach.
What happened to the Milky Way’s sister galaxy?
Cosmic cannibalism, or the merging of small galaxies with larger ones, happens all over the universe. We now know that the Milky Way lost a sister galaxy to Andromeda, and we’re now a step closer to understanding what might ultimately happen when Andromeda comes for us.
The Jupiter Analog Companions to Super-Earths
Today’s authors search for Jupiter analogs in foreign star systems to see how these giant worlds might affect the development of planets closer to the sun.
A different kind of planetary ring
Higher-order effects are beginning to surface in the photometry of exoplanets. Today we look at the way particles can add a ring to an exoplanet’s silhouette.
SETI on the Side: Seeking Dyson Spheres with Gaia
Could Gaia’s immense catalog of stellar positions help us find extraterrestrial intelligence?
