Homework Answers
Binary stars can be detected optically in that case they are called visual binaries .
Binary stars can also be detected with the help of spectroscopy, astrometry and can be detected during change in brightness of eclipses by photometric binaries.
Binary star system is a combination of two star system in which both the star move about their barycentre .
Star having greater mass have short orbit & star having
smaller mass have larger orbit.

The two stars in a binary star system have masses 2.0 times 10^30 kg and 5.8 times 10^30 kg. They are separated by 1.7 times 10^12 m. What is the system's rotation period, in years? What is the speed of the lightest star? What is the speed of the heaviest star?

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...

The two stars in a binary star system have masses 2.2×1030 kg and 5.8×1030 kg . They are separated by 2.3×1012 m . What is the system's rotation period, in years? What is the speed of the lightest star? What is the speed of the heaviest star?

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 binary star system has two stars, each with the same mass as our sun, separated by 1.50×1012 m . A comet is very far away and essentially at rest. Slowly but surely, gravity pulls the comet toward the stars. Suppose the comet travels along a straight line that passes through the midpoint between the two stars. What is the speed at the comet's midpoint?

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

Suppose you find a binary star system in which the more massive star is a red giant and the less massive star is a main-sequence star. Would you expect that mass transfer between the stars has played an important role in the evolution of these stars? Explain your reasoning.

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....

Sirius, the brightest star in the sky, is actually a binary system. Sirius A is a main sequence star of two solar masses in orbit with Sirius B, a white dwarf star. Assuming the two stars orbit each other with an average radius of 19.85 AU, what is the period of their orbit? What is their average tangential velocity? Warm Up
