Exoplanetary Wiki

This mini-wiki is intended to collect all interesting facts about exoplanetary systems. Planetary System articles are not written in encyclopedic format, but rather in bullet form. This can really be considered a "scratch-pad" for exoplanetary systems information, just jot down notes as seen fit. Links to other sites, message board threads, and news articles are encouraged. When creating a new system, please copy the the page Stellar System Boilerplate and fill in the details.

This wiki started out as a set of "System of the Day" posts at the bullitin board of the Extrasolar Visions web site. Concepts and terminology found in that web site are supported in this wiki. Speculations are also welcome.

Substellar Systems in the News
Index of systems that have been in the news. Sorted by the date of the most recent headline news the system is featured in. Each system should only appear once in this list.

Systems of 2007

 * Corot-exo-1 System (May 07) - Planet b is the first exoplanet discovered by the Corot satelite.
 * HD 147506 System (May 07) - Hat-P-2b is the most massive transiting exoplanet discovered, has very eccentric orbit.
 * Gliese 581 System (Apr 07) - Planet c is the first terrestrial world found within its star's habitability zone.
 * HD 209458 System (Apr 07) - Has famous "inflated" transiting hot Jupiter "Osiris". They detected water in its atmosphere (they had failed earlier), the first time this has been done for any exoplanet.
 * HD 189733 System (Feb 07) - Planet b is the nearest transiting exoplanet (62.9 ly). It is the first exoplanet to have its infrared spectrum measured.  They failed to find water, but dark silicate clouds might be covering them up.
 * Helix Nebula (Feb 07) - The nearest planetary nebula. The dust observed may be from thousands of comets banging into each other.
 * Mira System (Jan 07) - Well known binary star. It was found that material from the dying red giant was being syphoned off by the white dwarf in the system, beginning a new planetary system.
 * 51 Pegasi System, HD 179949 System (Jan 07): Tidally locked Hot Jupiters in these systems were found to have supersonic winds that caused the eternal night-side hemisphere to be as hot as the day-side one.

Systems of 2006

 * G29-38 System (Dec 06) - White dwarf star found to have a debris disk thought to be the result of an asteroid collision.
 * Tau Bootes System (Nov 06) - First planet-bearing star to have its magnetosphere probed. Hot Jupiter is embedded within it.
 * 54 Piscium System (Oct 06) - Nearby star with an eccentric planet. A very faint T type brown dwarf was recently discovered orbiting the star.
 * Epsilon Eridani System (Oct 06) - Planet b found to be the first planet known to orbit within the protoplanetary disk it was formed in.
 * Upsilon Andromedae System (Oct 06) - Well known multiplanet system. Roaster Planet b found to be hot on one side and cold on the other.
 * Sweeps 10 System (Oct 06) - One of first Ultra-Short-Period Planets detected near the Galactic Bulge. Orbits small star in only 10 hours.
 * WASP-1 System, WASP-2 System (Sep 06) - Have transiting Hot Jupiters, the first planets detected by the UK SuperWASP program.
 * GSC 03549-02811 System (Sep 06) - Discovery of transiting planet TrES-2, which was the most massive nearby transiting planet known at the time.
 * Mu Arae System (Aug 06) - Nearby multiplanet system that contains the first Neptunian discovered. Recent discovery of Planet e in the habitable zone made this the second known four-planet system after 55 Cancri.
 * HD 69830 System (May 06) - First multi-planet system found that does not have a Jupiter-sized planet. Contains 3 Neptunians and an asteroid belt.
 * OGLE-2005-BLG-390L System (Jan 06) - Has smallest yet detected exoplanet orbiting a star at the time. Has five times Earth's mass.  Detected by micro-lensing.

Systems of 2005

 * BD +20 307 System (Jul 05) - Sunlike star with a warm dust disk which may be signs that an Earth-like planet is forming there.
 * HD 188753 System (Jul 05) - First triple star system found to have a planet, which was nicknamed "The Tatooine Planet".
 * Gliese 876 System (Jun 05) - Very nearby triple planet system. Contains the first found rocky planet around a normal star (the first "Super-Earth").
 * 2M1207 System (May 05) - Has a "planet" orbiting a brown dwarf, which is possibly the first planet imaged.
 * GQ Lupi System (May 05) - Contains a planet that might be the first planet imaged.
 * GSC 02652-01324 System (Mar 05) - Contains well-studied transiting planet TrES-1, whose light was separated from its host star.
 * OTS 44 System (Jan 05) - Very low mass Brown Dwarf found to have a circumstellar disk.

Systems of 2004

 * Gliese 436 System (Sep 04) - Nearby red dwarf that contains one of the first Neptunians discovered.
 * 55 Cancri System (Sep 04) - Nearby multiplanet system that contains one of the first Hot Neptunians discovered.
 * OGLE-TR-113 System and OGLE-TR-132 (Apr 04) - 2nd and 3rd Very Hot Jupiters discovered.

Systems of 2003
OGLE-TR-113 System - Contains first Very Hot Jupiter discovered. Discovered by transit, confirmed with Dopplar Spectroscopy.
