What Caused the Ejection of Mu Columbae and AE Aurigae from Orion?

In summary, during a discussion on the regional NPR station, it was mentioned that the two brightest stars in the Columba constellation are Alpha and Beta Columbae, with Mu Columbae being the most famous. Mu Columbae is a "runaway star" that was ejected from near Orion's Trapezium Cluster due to a binary interaction involving another massive star and a third binary system. This event occurred approximately 2.5 million years ago and may have been caused by a supernova explosion. There are different theories about the origin of Mu Columbae, with one suggesting it was originally part of a binary system with AE Aurigae. Further research is being conducted to gain more insight into this topic.

I was listening to the regional NPR station yesterday and hear a brief discussion of two binary systems.

http://stardate.org/radio/program.php?f=detail&id=2009-12-26

The two brightest stars in Columba are Alpha and Beta Columbae. They're a bit fainter than most of the stars of the Big Dipper. Alpha Columbae is a blue star that's about 260 light-years from Earth. Orange Beta Columbae is only about a third as far.

The most famous star in Columba, however, is a still-fainter member of the constellation: Mu Columbae, a massive star that's racing away from Orion. It's 1300 light-years away. Mu Columbae probably was thrown out of the Orion Nebula, a cloud of gas and dust that has thousands of newborn stars.

According to one scenario, Mu Columbae and another massive star orbited each other as a binary in Orion. But the system encountered another binary. One star in that system stole Mu Columbae's partner, ejecting its own partner to the north, where it's racing through the constellation Auriga. The encounter sent Mu Columbae hurtling to the south, . . . .
Is this common? Is it plausible? I presume that some how the velocity of Mu Columbae and the other star traveling 'north' can be traced back to some neighborhood.

Mu Columbae is a "runaway star" that was ejected from near Orion's Trapezium Cluster 2.5 million years ago along with Auriga's AE Aurigae as a result of a binary interaction that also involved Na'ir al Saif (Iota Orionis).

A different scenario - http://jumk.de/astronomie/big-stars/mu-columbae.shtml
The big blue star once was the partner of AE Aurigae. The stars came into existence together in the Orion Nebula and since then drift away with high speed. Reason for this could have been a supernova explosion a long time ago.

@Astronuc did you find any more insight on this topic?
 

1. What are binary star interactions?

Binary star interactions refer to the gravitational interactions between two stars that are orbiting around each other. These interactions can lead to various phenomena such as mass transfer, tidal effects, and even mergers between the two stars.

2. How do binary star interactions affect the evolution of stars?

Binary star interactions can significantly affect the evolution of stars. They can change the mass, temperature, and luminosity of the stars involved, and can even lead to the formation of new types of stars. These interactions are also responsible for the creation of various astronomical objects such as planetary nebulae and supernova remnants.

3. Can binary star interactions lead to the formation of planets?

Yes, binary star interactions can play a crucial role in the formation of planets. The gravitational forces between the two stars can cause disturbances in the protoplanetary disk, leading to the formation of gaps and concentration of materials that eventually coalesce into planets.

4. What observational techniques are used to study binary star interactions?

Various techniques are used to study binary star interactions, including radial velocity measurements, astrometry, and photometric observations. These techniques help in determining the orbital characteristics and physical properties of the stars involved, such as their masses, distances, and luminosities.

5. Can binary star interactions have an impact on our solar system?

While our solar system is not a binary star system, it is possible for binary star interactions to have an impact on it. For example, if a binary star system passes close to our solar system, it can potentially disrupt the orbits of planets and comets, leading to changes in the dynamics of our solar system.
