Better known in the scientific community as IC 405, Sh 2-229, and Caldwell 31, the Flaming Star Nebula stands as an emission and reflection nebula. This celestial body is situated approximately 1,500 light-years away from us, nestled in the Auriga constellation. This wonder of the universe was first brought into human knowledge on the 21st of March, 1892, thanks to the efforts of John Martin Schaeberle.
At the heart of this nebula, powering its ethereal glow, is the star AE Aurigae. This star, an O9.5V-type Orion-type variable star, boasts a formidable mass of around 23 solar masses and an incredible temperature of 33,000 Kelvin. Orion-type variables are a fascinating class of stars known for their unpredictable and eruptive luminosity variations. Usually, these stars are found in association with diffuse nebulae, adding to their mystery.
Interestingly, AE Aurigae, despite appearing to envelop the Flaming Star Nebula, was not born within it. In fact, AE Aurigae is what astronomers term a 'runaway star'. Tracing its proper motion leads scientists to believe its origins lie in the Trapezium Cluster within the Orion Nebula.
The prevailing theory among astronomers is that AE Aurigae was most likely hurled into the cosmos following a collision of two binary stars. This violent encounter probably also resulted in the ejection of Mu Columbae and 53 Arietis approximately 2-3 million years ago.
These 'runaway stars', as they are classified by astronomers, move through space at high velocities relative to the surrounding interstellar medium. This characteristic makes their study both challenging and intriguing.
To visualize this cosmic spectacle, consider the composite optical image of the Flaming Star Nebula captured with a small amateur telescope. The image, crafted using broadband filters (RGB), offers a glimpse into the fascinating universe that surrounds us. Credit for this stunning image goes to Karol R @astrobin.
