Fomalhaut

(fō`məlhôt'), brightest star in the constellation Piscis Austrinus (southern fish); Bayer designation Alpha Piscis Austrini; 1992 position R.A. 22^h57.3^m, Dec. −29°39'. A white, main-sequence star of spectral classspectral class,
in astronomy, a classification of the stars by their spectrum and luminosity. In 1885, E. C. Pickering began the first extensive attempt to classify the stars spectroscopically.

The star, also known as Fomalhaut A, is part of a triple-star system. Images made in 2004 and 2006 by the Hubble Space Telescope were believed to show a planet orbiting the star, but subsequent study has questioned that interpretation. The star's name is from the Arabic meaning "mouth of the southern fish."

Fomalhaut

(foh -măl-hawt) (α PsA) A white star that is the brightest in the constellation Piscis Austrinus. In 1983 the infrared satellite IRAS detected a shell of cool matter surrounding this star. The shell, which has a temperature of about 50 K, is thought to be solid material orbiting the star and forming a protoplanetary system. See also Vega. m_v : 1.16; M_v : 2.0; spectral type: A3 V; distance: 6.7 pc.

Fomalhaut

(also a Piscis Austrinus), the brightest star in the constellation Piscis Austrinus. With a visual stellar magnitude of 1.2, Fomalhaut is 14 times brighter than the sun. It is located at a distance of seven parsecs from the sun.
