Einstein's planet," formally known as Kepler-76b, is a "hot Jupiter" that orbits its star every 1.5 days. ... This artist's conception shows Kepler-76b orbiting its host star, which has been tidally distorted into a slight football shape (exaggerated here for effect). The planet was detected using the BEER algorithm, which looked for brightness changes in the star as the planet orbits due to relativistic BEaming, Ellipsoidal variations, and Reflected light from the planet. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

... Astronomers have used a new technique to see the faint light from a planet that is orbiting a distant star. ... Instead, astronomers found them by looking for telltale clues, such as how the light from a star dims when an exo-planet passes in front of it, or how it wobbles because of the pull of an exo-planet s gravity. Astronomers can learn a lot about exo-planets that move in front of their stars. This is because the starlight passes through the exo-planet s atmosphere on its way to Earth. ...

Thanks to numerous ground and space-based surveys, we are now aware of over 1800 planets orbiting other stars, with another nearly 5000 candidates from the Kepler Mission awaiting confirmation. ... The answer to this question lies in the study of young planets and their formation environments. In this talk I will show how high-precision time series data from space telescopes is beginning to illuminate the conditions surrounding planet formation and the star-disk connection. ...
