Phi1 Pavonis, latinized from φ1 Pavonis, is a single [10] star in the southern constellation of Pavo. It has a yellow-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.75. [2] The star is located at a distance of approximately 92 light years away based on parallax. It is drifting closer to the Sun with a radial velocity of −20 km/s. [5]
This is an ordinary F-type main-sequence star with a stellar classification of F0V. [3] It has 1.5 [6] times the mass of the Sun and 1.8 [1] times the Sun's radius. This is a young star, perhaps 30 [8] million years old, and has a high rate of spin with a projected rotational velocity of 150 km/s. [7] It is radiating 8.2 [1] times the luminosity of the Sun from its photosphere at an effective temperature of 7,209 K. [1]
Phi1 Pavonis is a candidate debris disk star, although Gray et al. (2006) reported a non-detection of an infrared excess. [3] Nilsson et al. (2010) report a marginal detection, orbiting 74 AU from the host star with a temperature of 57 K and an estimated 3.1±1.7 times the mass of the Moon. [8]
