A-type star in the constellation Eridanus
Tau3 Eridani ,Latinized fromτ3 Eridani , is astar in theconstellation Eridanus . It is visible to the naked eye with anapparent visual magnitude of 4.10.[ 2] parallax method ,[ 1] light years . In 2001 it was reported as a candidateVega -like star, meaning it appears to radiate aninfrared excess from an orbitingcircumstellar disk .[ 11] [ 12]
This is anA-type star with astellar classification of A3 IV-V.[ 3] luminosity class of IV-V indicates the spectrum displays traits intermediate between amain sequence andsubgiant star . It is around 476[ 6] projected rotational velocity of 133 km/s.[ 9] [ 13] 3 Eridani has 178%[ 6] Sun's mass and nearly double theradius of the Sun .[ 7] solar luminosity from anouter atmosphere at aneffective temperature of 8,251 K.[ 6]
