In summary, stars are born when gas compresses and ignites a fusion reaction. Binary stars are formed when a large volume of gas partitions during compression into two different stars, and end up as binaries to conserve angular momentum. If one star is much bigger than the other, the big/primary usually burns its fuel faster, ends up as a white dwarf, accretes material from the binary companion, reach critical mass and explodes while synthesising heavier elements. If you are a good poet you can turn simple ideas into complex, convoluted, romantic verses :)

Does anyone else find it cosmically romantic the significance of binary stars? The fact that they orbit a common area, looping around each other is stuff that poems, are made of.. Anyway, I'm a hopeless romantic, but I love the idea, its just really beautiful if you think about it..Any how, does anyone know how these systems are formed? Have most always been a pair, or do they slowly drift until they find each other?

stars are formed by gases compressing to a critical density and igniting a fusion reaction. binary stars are formed when a large volume of gas partitions during compression into two different stars, they end up as binaries to conserve angular momentum. or drifting stars that are influenced by each others gravitational field can also end up as binary system to conserve angular momentum.
in cases where one star is much bigger than the other, the big/primary usually burns its fuel faster, ends up as a white dwarf, accretes material from the binary companion, reaches critical mass and explodes while synthesising heavier elements.

It's worth noting that MOST stars are in multiple-star systems, dominated by binaries. As the above discusses, they form in the same stellar nursery and are gravitationally bound to each other from their conception. By contrast, while it is possible for two single stars to come together to form a gravitationally bound binary system, such an interaction is exceedingly rare. What would happen almost 100% of the time is the bodies would simply scatter off each other and fly away in different directions.

Could you form a romantic idea about a globular cluster, please?

The birthing of multiple star systems is still being debated. The two leading contenders are fission and fragmentation, although computer simulations are not entirely successful at replicating either. As Nabeshin noted, gravitational capture is not a contender, save in the case of globular clusters where tidal captures are more common [albeit still rare] than in less densely populated regions [re: http://www.nasa.gov/centers/marshall/news/news/releases/2003/03-130.html] .

Mother Sun and Father Gravity

Hydrogen atoms drifting in space Father Gravity captivated
Atoms in the vicinity felt His attraction and were accelerated
Each atom joined a brother, proving the Laws of Nature cooperated
For thousands of centuries a huge cloud of hydrogen gas accumulated
Containing more atoms than anyone had ever contemplated

During untold billions of years Hydrogen molecules congregated
Drifting in the cosmos, the massive gas cloud was created
Into a hot dense core the molecules concentrated
To become a protostar they were fated
Because Father Gravity’s intense hug never abated

Pressure and temperature rose so high the atoms incinerated
In the process a tiny fraction of their mass annihilated
Energy, proving Prophet Albert correct, was liberated
Electromagnetic energy was immediately radiated
Out into space at the speed of light photons propagated

After a meal a Primitive Man and His Family luxuriated
Their gardens and orchards Mother Sun illuminated
Mother Sun and Father Gravity the Family appreciated
The gift of Life-giving Light they celebrated
And Mother Sun and Father Gravity they venerated

Wow that is beautiful... It accurately describes the birth of a star and it's progression to a main sequence star (poetically of course) without feeling the slightest bit forced at any time. Not an easy task!
 

FAQ: The Cosmic Romance of Binary Stars: How Are They Formed?

1. How do binary stars form?

Binary stars form through the gravitational collapse of a large cloud of gas and dust, which leads to the formation of two separate protostars. As the protostars continue to accrete material, they begin to orbit each other due to their mutual gravitational attraction, eventually becoming a binary star system.

2. What determines the characteristics of a binary star system?

The characteristics of a binary star system, such as the distance between the two stars, their masses, and their orbital period, are determined by the initial conditions of the gas cloud from which they formed. Factors such as the size and rotation of the cloud, as well as the amount of gas and dust present, can all influence the formation and characteristics of the binary stars.

3. How common are binary stars?

Binary stars are actually quite common, with some estimates suggesting that as many as 50% of all stars in our galaxy are part of a binary or multiple star system. However, the majority of these binary stars are too far away to be observed individually, so they appear as a single point of light in the night sky.

4. Can binary stars have planets?

Yes, binary stars can have planets orbiting around them, just like single stars. However, the presence of a second star in the system can affect the formation and stability of planets. Some binary star systems have been found to have planets orbiting both stars, while others have only one star with planets.

5. How do binary stars evolve over time?

As binary stars age, their evolution is influenced by their mutual interactions and the exchange of mass between them. Depending on their masses and distances from each other, the stars may eventually merge or one may become a white dwarf, while the other continues to shine as a main sequence star. The exact fate of a binary star system depends on its unique characteristics.
