![Binary Stars Q1) A binary star system has a distance from Earth of 42.2 light years. The distance between the stars is 1.08 x 101 m and the rotation period is 104 days. Assume equal masses of the stars, and circular orbits (centre of mass of the system is at rest relative to the Earth). a) Calculate the speed of the stars relative to the centre of mass of the system. Further assume the stars emit particles with a relative velocity of 3.0x108 m/s. b) How long does it take on average for these particles to reach the Earth? Dont overthink this one.] c) What is the time difference with which two particles reach Earth if they were emitted at the same time, one from the star moving away from Earth at the maximum velocity and the other from the star moving towards Earth at the maximum velocity?](http://img.homeworklib.com/questions/a0e713d0-0230-11ec-913a-199395ea5558.png?x-oss-process=image/resize,w_560)

4) A binary star system consists of two stars, one of which is 1 solar mass and one of which is 2 solar masses. They are separated by a distance of 5 astronomical units and have approximately circular orbits. a) What is the orbital period of each star? b) What is the orbital velocity of each star? c) What is the angular momentum of the two star system, assuming that each star's radius is much smaller than its orbital radius?

A certain binary star system consists of two stars with masses m1 and m2, separated by a distance b. A comet, originally nearly at rest in deep space, drops into the system and at a certain point in time arrives at the midpoint between the two stars. For that moment in time, find its velocity, v, symbolically in terms of b, m1, m2, and fundamental constants. p

Plaskett's binary system consists of two stars that revolve in circular orbits around a fixed point half-way between them. This means that the masses of the two stars are equal (see the figure below). --- M If the orbital velocity of each star is v= 188 km/s and the orbital period of each is 11.7 days, calculate the mass Mof each star. (For comparison, the mass of our Sun is 1.99x1030 kg.)

Consider a binary star system that has bright lines at 656.72 and 656.86 nm. Over the course of six months the 656.72-nm line moves to longer wavelength and the 656.86-nm line moves to shorter wavelength, until finally the two have swapped (i.e., the spectrum of the star system again shows bright lines at 656.72 and 656.86 nm). Assume that the stars are of roughly equal mass and moving in a circular orbit with axis perpendicular to the line connecting the...

In a particular binary star system, only one star is visible because the other star is too faint to see at that distance. An astronomer measures the size (semimajor axis) and period of the orbit of the visible star. From this information the astronomer can calculate nothing about the mass—both stars have to be visible to do so. the mass of each star. the sum of the masses of the two stars but not the mass of each star separately....

Alpha Centauri A and B are Sun-like stars, and together they form the binary star Alpha Centauri AB. Alpha Centauri A has 1.1 times the mass of the Sun, while Alpha Centauri B has 0.907 times the Sun’s mass. (Sun’s mass is 1.989 × 1030 kg.) The pair orbit about a common centre with an orbital period of 79.91 years. Their elliptical orbit is eccentric, so that the distance between A and B varies, but if we assume it is...

5- Consider a binary system composed of a star 1 and a star 2 that both have very eccentric orbits (el = e2 = 0.500). They both take 3.00 months to complete an orbit but the semi-major axis of star 2 is three times larger than that of star 1. The two stars are very close to each other since the sum of their semi-major axes is 0.500 AU. They both lie 50.0 ly from us. a) Make a somewhat...

In a certain binary-star system, each star has the same mass which is 3.7 times of that of the Sun, and they revolve about their center of mass. The distance between them is 6.9 times the distance between Earth and the Sun. What is their period of revolution in years?
