A planet about eight times the mass of Jupiter has been confirmed to orbit a sun-like star that's some 300 times farther from its own star than Earth is from its sun. The newly confirmed planet is the least massive planet known to orbit at such a great distance from its host star.

A planet about eight times the mass of Jupiter has been confirmed to orbit a Sun-like star that's some 300 times farther from its own star than Earth is from its sun.

The newly confirmed planet is the least massive planet known to orbit at such a great distance from its host star.

The discovery, first reported in September 2008, was made using high-resolution adaptive optics technology at the Gemini Observatory. These latest results, published in the Astrophysical Journal, were led by David Lafrenière of the University of Montreal Department of Physics and a researcher at the Center for Research in Astrophysics of Quebec.

The suspected planetary system required further observations to confirm that the planet and star were indeed moving through space together. "Back in 2008 what we knew for sure was that there was this young planetary mass next to a young Sun-like star," says Lafrenière. The extreme proximity of the two objects strongly suggested that they were associated and not just aligned by chance.

"Our new observations rule out this chance alignment possibility, and thus confirms that the planet and the star are related to each other," says Lafrenière.

With its initial detection by the team using the Gemini Observatory in April of 2008 this object became the first likely planet known to orbit a sun-like star that was revealed by direct imaging. At the time of its discovery the team also obtained a spectrum of the planet and was able to determine many of its characteristics, which are confirmed in this new work.

"In retrospect, this makes our initial data the first spectrum of a confirmed exoplanet ever," says Lafrenière, adding the images show water vapor, carbon monoxide and molecular hydrogen in the planet's atmosphere.

David Lafrenière, along with René Doyon and Christian Marois, received the 2009 NSERC John C. Polanyi Award for capturing the first-ever image of a planetary system outside of our own solar system.
