|
The Flaming Star Nebula
|
|
IC405 is a large (37’ by 19’) reflection nebula in Auriga, traditionally known as The Flaming Star Nebula. It is illuminated by a central star, AE Aur (HD 34078), which is a runaway from the Orion Nebula.
AE Aur is thought to have been ejected from Orion roughly 2.5 million years ago in a binary-binary interaction.
AE Aur is moving with a large proper motion through the nebula (17 AU/yr), and has been traditionally observed to study spectral time variations.
