Lightcurve folding is frequently used to make signals in the data clearer. Today’s author describes a novel way to use the folding method to pick out exomoon signals from exoplanet transit lightcurves.
Traces of planets devoured by their host stars can possibly be found within the external layers of the stellar surface. These remains tell a story of the evolution and architecture of different planetary systems and grant new appreciation for our relatively calm environment.
The search for exomoons orbiting rogue planets.
Astronomers have caught the first directly-imaged exoplanet gravitationally tugging at its host star – thereby revealing its own weight.
This exoplanet has…a tail?! Read on to learn about how astronomers studied the atmosphere of exoplanet WASP-107b and clues they found about atmospheric escape.
Most planets in our solar system have multiple moons, from Mars’ 2 to Saturn’s ~82. Today’s paper explores the stability and detectability of multi-”exomoon” systems orbiting planets beyond our solar system.
