We measure rotation periods for 12151 stars in the Kepler field, based on the photometric variability caused by stellar activity. Our analysis returns stable rotation periods over at least six out of ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

Stars are not perfect spheres. While they rotate, they become flat due to the centrifugal force. A team of researchers around Laurent Gizon from the Max Planck Institute for Solar System Research and ...

Using asteroseismology, an international research team has discovered a surprising alignment of the rotation axes of stars in open clusters, shedding light on the conditions in which stars are formed ...

For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an aging star. The doomed world appears destined to spiral closer and closer to its expanding star until they ...
