Summary: TEHRAN (FNA)- Three extrasolar comets have been discovered around the star Beta Pictoris
, 63 light years away.
The astronomers pinned Beta Pictoris
b's mass to between 9 and 13 times that of Jupiter.
The researchers proved the theory after testing it on the images - taken by ESO's SINFONI instrument - of a star named Beta Pictoris

A day on the planet Beta Pictoris
b is roughly eight hours long--shorter than on any planet in the solar system, the team reports in the May 1 Nature.
The scientists were able to identify the orbit of the exoplanet, Beta Pictoris
b, which sits 63 light-years from our solar system, by using the Gemini Planet Imager's (GPI) next-generation, high-contrast adaptive optics (AO) system.

. An intensive study around the magnitude 3.8 white-coloured type A3 star, 63 light years away, is being undertaken of late.
Los astronomos del Observatorio Steward de la Universidad de Arizona, Estados Unidos, obtuvieron imagenes de Beta Pictoris

The group, comprising researchers from the National Astronomical Observatory of Japan, Nagoya University and Hokkaido University, has observed Beta Pictoris
, a star thought to resemble the young sun.
Later photographs revealed an edge-on debris disk around the southern star Beta Pictoris
. In the late 1990s, Hubble's second-generation instruments, which had the capability of blocking out the glare of a central star, allowed many more disks to be photographed.
"That was the night where we said, 'y'know, let's just point it at a damn planet and see what it looks like.'" The team slewed the telescope toward Beta Pictoris
, a star 63 light-years from Earth with a hot, young giant planet that orbits its star at almost twice the distance that Jupiter orbits the Sun.
