Binary stars orbiting around each other are equidistant [closed]
This is a problem that was given to me in my Classical Mechanics course:
J.S.Plaskett's star is one of the most massive stars known at present. It is a binary star, that is, it consists of two stars ...

Solving for the mass of the larger star in a binary star system. (Larger star is much larger, so orbit is essentially circular)
I'm a teaching assistant for a class on Newtonian mechanics, and was confronted with a way of solving for the larger mass in this two-star system that gets the right symbolic solution, but seems to ...

Can Binary Stars Escape Each Other?
updated 8/27/2020
While the recession of our Moon from the Earth may slow and even stop,
(see When will the Moon reach escape velocity?)
binary star systems will
(1) never stop experiencing mutual ...

Definition of eclipsing binaries?
In the second minimum (the 3rd step) there is a smaller decrease in light intensity. For this to happen, wouldn't you need to be looking at the plane of orbit from above rather than directly along the ...

Gravitational force between astronomical bodies in a binary system
If two celestial bodies of similar mass form a binary system and both have fairly relativistic velocities does in that case gravity act with delay and does the picture shown present the problem in the ...

Ratio of masses of double star problem
I am currently studying Classical Mechanics, fifth edition, by Kibble and Berkshire. Problem 2 of chapter 1 is as follows:
The two components of a double star are observed to move in circles of radii ...

Question about proportionally rules
I don't think context is needed but to make sure: I'm doing a homework exercise on binary system. P is the orbital period and E the energy of the system. The following is in the solution when trying ...

How do tidal forces change gravitational waves
If there is a binary of two neutron stars, they are going to be deformed because of the tidal forces. I suppose that it will cause a change in the movement of the stars and that will cause a change in ...

Eccentricity of two bodies in an unbound orbit
There seems to be two definitions of an eccentricity of orbiting bodies, one for when it’s not bound and the other for when it is bound (Keplerian binary).
When the binary is bound there is a simple ...

Derive hamiltonian from equations of motion
Is there a method for deriving the hamiltonian given that you know the equations of motion?
For example given the equation (equation 5 in paper linked) they simply the derive the Hamiltonian in ...

Discerning binary stars
What is the minimum magnification that one would need to discern a pair of binary stars if viewed from Earth? Are there factors other than magnification that matter? If so, why?

In which direction would gravitational waves be emitted when two black holes colide?
Imagine two black holes on the x-axis coming together at the origin (not rotating around each other, just falling towards each other).
In which direction would the most intense gravitational waves be ...

Why do gravitational waves circularize a binary?
I understand that a binary orbiting around one another will circularize due to the emission of GWs due to Peters equations and that highly eccentric binaries evolve faster.
But GW emission also ...

Are there any black hole neutron star binary?
Has a black hole-neutron star binary aver been observed?
I mean observed in any way: gravitationally, through eclipse, or any other means.
EDIT Thanks to the comment to this question, we know that ...
