Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
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.
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.
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.
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.
Could Gaia’s immense catalog of stellar positions help us find extraterrestrial intelligence?
