Delta Pavonis is a yellow-orange main sequence dwarf star of spectral and luminosity type G5-8 V-IV. This star has about 1.1 times Sol's mass (RECONS), 1.06 times its diameter (Johnson and Wright, 1983, page 695), and about 1.18 times its luminosity. The star may be 95 percent to 2.7 times as enriched as Sol with elements heavier than hydrogen ("metallicity") based on its abundance of iron (Cayrel de Strobel et al, 1991, page 306), but although probably older than Sol, its exact age is uncertain (Harmer et al, 1970; and Alexander William Rodgers, 1969). It has a New Suspected Variable designation NSV 12790 and appears to be unusually bright for its spectral type, and so may be becoming a subgiant star that is beginning to evolve off the main sequence, as it begins to fuse the increasing amounts of helium "ash" mixed with hydrogen at its core. Since Delta Pavonis is fairly similar to our Sun, many speculate whether it might contain planets that harbor life.
