μ Fornacis (Latinised as Mu Fornacis) is the Bayer designation for a star in the southern constellation of Fornax. With an apparent visual magnitude of 5.27,[2] it is visible to the naked eye. The distance to this star, as determined by its annual parallax shift of 10.18 mas,[1] is around 320 light years.
This is an A-type main sequence star with a stellar classification of A0 V.[3] It is a Be star that displays "central quasi emission" (CQE) bumps in its spectrum due to a surrounding shell of material.[10] The star has an estimated 3.1[6] times the mass of the Sun and 2.5[7] times the Sun's radius. Mu Fornacis is spinning rapidly with a projected rotational velocity of 320 km/s[3] and is around 188 million years old.[6] It radiates 68.7[8] times the solar luminosity from its outer atmosphere at an effective temperature of 11,745 K.[6]
Mu Fornacis appears to be emitting an infrared excess at a wavelength of 22 μm, which could be due to an orbiting debris disk.[11]
