Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system. Assume that Star 1 has m1 = 3.2 solar masses, Star 2 has m2 = 1.6 solar masses, and the total separation of the two (R) is 80 AU. (One AU is Earth's average distance from the Sun.) (a) What is the distance, d1, (in AU) from Star 1 to the center of mass?

(a) The figure shows the three stars and their velocities. Which star has the largest proper motion? Which star has the smallest proper motion? A B Earth

(Astronomy) Binary Pulsar. Part A: Use the orbital period 27 min for the binary pulsar (two neutron stars orbit each other) to find the orbital separation of the pair in AU and solar radii. Assume a neutron star's mass is 3 solar masses. (Hints: Use the version of Kepler's third law for binary stars.) Part B: Is this system orbiting closer or further than Mercury is to the Sun?

using the center-of-mass equations or the Carter of Mass Calculator (under Binary-Star Basics, abova), you will investigate a specific binary star system. Assume that Star 1 has m, 3.2 solar masses, Star 2 has m,-0.9 solar masses, and the total separation of the two (R) is 34 All (One AU is Earth's average distance from the Sun) (2) What is the distance, d. (In Au) from Star 1 to the center of mass? AU (b) What is the distance, dy On Au) from Star 2 to the center of mass AU ( what is the ratio of d, tod?

Problem Set on Binary Systems: 1.Consider two stars in orbit about a mutual center of mass. If a1 is the semimajor axis of the orbit of star of mass m, and a, is the semimajor axis of the orbit of star of mass m2, prove that the semimajor axis of the orbit of the reduced mass is given by a = a, + a2. points)

If the mass of a star is 9.94  10^30 kg then what is Kepler's constant for that star?Reminder k = ( T^2 / R^3 )

What is the magnitude of the proper motion in tau Leonis

A supernova in a distant galaxy is observed to be having an absolute magnitude of -19 and an apparent magnitude of 17. Estimate the distance to the galaxy.

What is the total mass of a visual binary system if the average separation of the stars is 7.1 AU and their orbital period is 12 years?
