Beta Pictoris

(pik-tor -is, -toh -ris) (β Pic) A 4th-magnitude star in the constellation Pictor, about 19 parsecs from Earth. Following the IRAS survey in 1983, which showed the star to have an infrared excess, optical detectors revealed a disk of dust and ices surrounding the star. Seen edge-on from the Earth, this disk may be a region in which planets could form. Analysis of the disk in the late 1990s and early 2000s revealed a warp or bulge in its outer regions that may have been caused when material was pulled from the disk by the gravitational effect of a passing star, a brown dwarf companion, or a planet several times the mass of Jupiter. Beta Pictoris is a young star a little larger than the Sun. Mv : 2.42; spectral type: A5 V

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.
Move across to the eastern part of the constellation to pin-point beta Pictoris. 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 b, un planeta 7 a 10 veces la masa de Jupiter, junto a su estrella, Beta Pictoris, a 63 anos luz de la Tierra, gradas a un dispositivo optico que es una pequena pieza de vidrio con un patron muy complejo grabado en su supedide.
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.
