Binary Stars; Relativity Too

In summary, there are some new releases of interest in General Astronomy, including a discussion on the Physics Forums and an article about pulsar gravity. According to Dr. Vicky Kalogera, a neutron star merger could potentially be detected every one to two years by the first generation of gravitational wave detectors. This could potentially challenge current theories and lead to major modifications.

Under the most favourable distribution model, we can say at the 95% confidence level that this first generation of gravitational wave detectors could register a neutron star merger every one to two years," said Dr Vicky Kalogera, Assistant Professor of Physics and Astronomy at Northwestern University in Illinois, USA.

thanks for origonal post LAB GUY.
it seems the axe may fall on some theories in a very few years,
or be subject to major modification, when null results are
returned from LIGO etc, i just wounder how much "wiggle", room
will be left after these null results.
 

1. What are binary stars?

Binary stars are a type of star system in which two stars are gravitationally bound to each other, orbiting around a common center of mass. They are often close to each other and can be seen as two distinct stars from Earth.

2. How do binary stars form?

Binary stars form when a cloud of gas and dust collapses under its own gravity. As the cloud collapses, it breaks into smaller fragments, with each fragment forming a separate star. If the fragments are close enough, they will become gravitationally bound and form a binary star system.

3. What is the significance of binary stars in astronomy?

Binary stars are important in astronomy because they provide a unique opportunity to study the properties and evolution of stars. By observing the orbit of the stars, scientists can determine their masses and calculate other important variables. Binary stars also play a role in the formation of planetary systems.

4. How does relativity come into play with binary stars?

Relativity is important in understanding binary stars because it helps to explain the behavior of the stars as they orbit each other. According to Einstein's theory of general relativity, the massive stars will warp the space-time around them, causing the orbits to deviate from what would be expected based on Newton's laws of motion.

5. Can binary stars ever merge or collide?

Yes, binary stars can merge or collide, but it is a rare occurrence. When two stars are close enough, they can merge to form a single, more massive star. If the stars are too close, they may collide and create a supernova explosion. This can happen in some binary star systems with very short orbital periods.
