Phi2 Pavonis


Phi2 Pavonis (φ2 Pav, φ2 Pavonis), also known as HD 196378, is a yellow-white dwarf star approximately 82 light-years away in the constellation of Pavo (the Peacock). It is evolving into a subgiant.
This system was in 1991 a test case for the Zeta Herculis moving group, of low metallicity stars with 5 billion years of age. This group includes besides Zeta Herculis: δ Trianguli, ζ Reticuli, 1 Hydrae, Gl 456, Gl 678, and Gl 9079.
In 1998, using the European Southern Telescope in Chile, a planet was announced to be orbiting the star. This team retracted this claim in 2002, but found a different periodicity of 7 days possibly due to stellar rotation.
