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...
An exoplanet may seem like the perfect spot to set up housekeeping, but before you go there, take a closer look at its star.Rice University astrophysicists are doing just that, building a computer mod...
The International School for Young Astronomers on Stars and Exoplanets will be held in November 26th to December 9th, 2017 in Kunming, China, under the organization of Yunnan Observatories (YNOs) of C...
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 exoplanetsnearly 3,500 have been confirmed so ...
2017SPIE探测系外行星的技术和仪器专题会议(Techniques and Instrumentation for Detection of Exoplanets VIII)。
Brown dwarfs are smaller than stars, but more massive than giant planets. As such, they provide a natural link between astronomy and planetary science. However, they also show incredible variation whe...
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 – 400 ìm wavelength range, a far-IR interferometer will revolutionize our understanding of planetary system format...
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...
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 ...
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...
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...
We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate the mo...
Transiting planet discoveries have largely been restricted to the short-period or low-periastron distance regimes due to the bias inherent in the geometric transit probability. Through the refine-ment...
