HD 196050

HD 196050 is a triple star[7][3] system located in the southern constellation of Pavo. This system has an apparent magnitude of 7.50[2] and the absolute magnitude is 4.01.[2] It is located at a distance of 112 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +61 km/s.[2] It is also called by the Hipparcos number 101806.

The primary component is a G-type main-sequence star with a stellar classification of G3V.[4] It has a quiescent chromosphere and does not appear to be variable.[7] The star has 18%[1] more mass than the Sun and a 46% greater size. It is around 2.5 billion years old with a higher than solar metallicity, and is spinning with a projected rotational velocity of 3 km/s.[5] The star is radiating 2.21[1] times the luminosity of the Sun from its photosphere at an effective temperature of 5.834 K.[1]

A faint co-moving companion star, designated component B, was detected based on observations during 2003–2004,[7] located 10.80″[3] to the south of the primary component. This corresponds to a projected separation of 7,511±22 AU.[7] The star is magnitude 10.62[3] A third companion, component C, was discovered in 2007, located about 0.4″ from component B.[8] It has a visual magnitude of 15.6.[3]

In 2002, the Anglo-Australian Planet Search team announced the discovery of an extrasolar planet orbiting the star.[9] The discovery was independently confirmed by the Geneva Extrasolar Planet Search team.[10]
