In 1995, astronomers found the first known planet around a sun-like star outside our solar system. The news caused a buzz of excitement around the world. Finally we had proof of a planet orbiting anot...
Scientists at Cornell and the American Museum of Natural History have identified 2,034 nearby star-systems – within the small cosmic distance of 326 light-years – that could find Earth merely by watch...
Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so ...

EVANSTON, Ill. --- During its four-year mission, NASA’s Kepler space telescope discovered thousands of “planetary candidates” in our Milky Way galaxy -- the vast majority of which are almost certainly...
The Radial Velocity Signature of Tides Raised in Stars Hosting Exoplanets
stars: planetary systems – stars: solar type – hydrodynamics – waves – planet-star interactions
2011/10/18
Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximation. The predicted ra...

We present estimations of dipolar magnetic moments for terrestrial exoplanets using the Olson & Christiansen (2006) scaling law and assuming their interior structure is similar to Earth. We find that ...
Transiting exoplanets from the CoRoT space mission. XVIII. CoRoT-18b: a massive hot jupiter on a prograde, nearly aligned orbit
stars: planetary systems - techniques: photometry - techniques: radial velocities - techniques: spectroscopic
2011/9/30
We report the detection of CoRoT-18b, a massive hot jupiter transiting in front of its host star with a period of 1.9000693 +/- 0.0000028 days. This planet was discovered thanks to photometric data se...
The Great Escape: How Exoplanets and Smaller Bodies Desert Dying Stars
planet-star interactions planets supernovae: general
2011/9/29
Mounting discoveries of extrasolar planets orbiting post-main sequence stars motivate studies aimed at understanding the fate of these planets. In the traditional "adiabatic" approximation, a secondar...
In the search for Earthlike exoplanets, GJ 436b has much to tell us（图）

2010/4/28
Although we have yet to find an exoplanet, or planet outside our solar system, that is small and cool enough to resemble Earth and possibly host life, planetary scientists say it could happen within t...
Scientists working on NASA's Kepler mission have unveiled the first five exoplanets discovered by the space telescope since it was launched in March 2009. The exoplanets – planets orbiting stars other...

NASA's Kepler Space Telescope Five Exoplanets
2010/1/11
NASA's Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system.Kepler's hi...
