Instead of happily orbiting in circles with constant velocity, the two stars spend most of their time far apart, and a few harrowing hours racing past each other. Or, to put it another way: hours and hours of boredom punctuated by moments of sheer terror. This is a heartbeat star.
Artist’s impressions of exoplanets are often wrong!
There are nine Earth-like planets detectable in the Kepler data set… better get searching!
According to planet formation theory, gas giants are more massive than rocky, terrestrial planets. But Kepler-10c is the size of Neptune, and denser than the Earth! Read on to find out more about the discovery of a new class of planets.
Kepler-93b is a super-Earth with a radius of 1.481 Earth radii, plus or minus Long Island.
This paper introduces a new method of searching for occultations in Kepler data to study the albedos of close in super-Earths.
From examining extrasolar planetary systems, we can test if the Titius-Bode “law” is actually a law.
Exoplanets with moons could mimic alien life-signs.
How do pulsating stars give away their secret identities as binary dance partners? In this paper, the authors demonstrate a new way to not only detect binaries we may have missed in the Kepler data, but also to measure their velocities without spectra.
Kepler finds the signature of a transiting white dwarf. Instead blocking the light of its companion star, the white dwarf magnifies it, creating a light curve that periodically brightens.
