HD 196050 is a triple star[1][2] system located in the southern constellation of Pavo. This system has an apparent magnitude of 7.50[3] and the absolute magnitude is 4.01.[3] It is located at a distance of Шаблон:Convert from the Sun based on parallax, and is drifting further away with a radial velocity of +61 km/s.[4] It is also called by the Hipparcos designation HIP 101806.

Characteristics

The primary component is a G-type main-sequence star with a stellar classification of G3V.[5] It has a quiescent chromosphere and does not appear to be variable.[1] The star has 18%[6] 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.[7] The star is radiating 2.21[6] times the luminosity of the Sun from its photosphere at an effective temperature of 5,834 K.[6]

A faint co-moving companion star, designated component B, was detected based on observations during 2003–2004,[1] located Шаблон:Val[2] to the south of the primary component. This corresponds to a projected separation of Шаблон:Val.[1] The star is magnitude 10.62[2] A third companion, component C, was discovered in 2007, located about Шаблон:Val from component B.[8] It has a visual magnitude of 15.6.[2]

Planetary system

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] In 2023, the inclination and true mass of HD 196050 b were determined via astrometry.[11]
