Star in the constellation Fornax
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 .
