AE Aurigae (abbreviated as AE Aur) is a

runaway star in the constellation Auriga; it lights the Flaming Star Nebula
.

Description

Hipparcos light curves for AE Aurigae. The main plot shows the long-term variation, and the inset plot shows the variation folded over a period of 213.7 days. Adapted from Marchenko et al. (1998)[8]

AE Aurigae is a blue

light-years from Earth
.

AE Aur is a

Trapezium cluster in the Orion Nebula two million years ago. The binary Iota Orionis may have been the other half of this collision.[9]

Flaming star nebula
Nebula IC 405 around AE Aurigae

AE Aur is seen to light up the Flaming Star nebula, but it was not formed within it. Instead it is passing through the nebula at high speed and producing a violent bow shock and high energy electromagnetic radiation.[10][11]

Companions

Possibly due to its runaway star nature, AE Aurigae has no physical companion stars, although some nearby stars have been erroneously identified as ones. A theoretical companion 1000 AU (0.016 light-years) away from AE Aurigae would have an angular separation of less than 2.5 arcseconds and would probably be lost in the star's glare.[citation needed]
