Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0x10^11 solar masses. A star orbiting near the galaxy's periphery is 6.0X10^4 light years from its center. (For your calculations, assume that the galaxy's mass is concentrated near its center.) (a) What should the orbital period of that star be in yr ? (b) If its period is 6.0 x 10^7 years instead, what is the mass of the galaxy? Such calculations are used to...

Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0 x 1011 solar masses. A star orbiting near the galaxy's periphery is 5.7 x 104 light-years from its center. (a) What should the orbital period (in y) of that star be? 24.2e6 ху (b) If its period is 5.1 x 107 years instead, what is the mass (in solar masses) of the galaxy? Such calculations are used to imply the existence of other matter,...

Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0×1011 solar masses. A star orbiting on the galaxy’s periphery is about 6.0×104 light years from its center. What should the orbital period in years of that star be? (You do not need to enter any units.) 2.61×108 yr ¡Correcto! Su recibo es 160-1991 Intentos Anteriores If its period is 5.0×107 light years instead, what is the mass of the galaxy in solar mass? Such...

Astronomers have observed a small, massive object at the center of our Milky Way galaxy. A ring of material orbits this massive object; the ring has a diameter of about 10 light years and an orbital speed of about 210 km/s . A) Determine the mass of the massive object at the center of the Milky Way galaxy. Give your answer in kilograms. B) Give your answer in solar masses (one solar mass is the mass of the sun). C)...

Andromeda Galaxy, M31, is considered a sister galaxy to Milky Way galaxy. One similarirty is their masses (a) Astronomers have used orbiting satellite galaxies to calculate the mass. At a distance of 190 kpc from the center of M31, the circular velocity of these objects is 150 km/s. Using the measurements and tools that astronomers use, calculate the total mass of M31 in units of the mass of the Sun, M. Watch your units in your calculations! Here are few...

Astronomers have observed a small, massive object at the center of our Milky Way Galaxy. A ring of material orbits this massive object; the ring has a diameter of about 12 light-years. If this massive object at the center has a mass of 2.75 x 1037 kg, what is the material orbital speed? Give your answer in km/h.

The sun orbits the center of the Milky Way galaxy (see figure)
in a period of 2.5 108 years.
(a) Assuming a circular orbit of radius 2.12 1020 m, compute the
mass of the Milky Way.
(b) Estimate the number of stars in the Milky Way, assuming the
average star mass equals the mass of the sun—2.0 1030 kg. units

The trajectory of one star (S2) around the center of the Milky Way, or Sagittarius A*. The semimajor axis of the star S2’s orbit is aS2 = rp/(1−e) =1.4∗1014m. Derive the mass that S2 is orbiting if the period is 16.0518 yr.

It is said that at the center of every galaxy is a supermassive black hole (the picture below shows a picture towards the center of the Milky Way from the Keck Observatory). By observing the orbits of nearby stars, you can get a crude estimate of the mass of this black hole by assuming the stars have a circular orbit. Consider the star SO-2, which has an orbital period of 16.3 years. Its average distance from the black hole is...

3. In this problem, we are going to examine the supermassive black hole in the center of our galaxy, Sagittarius A.. (a) (15 points) We can calculate its mass using the orbits of stars gravitationally bound to it in the same way that you can use the Earth's orbit to calculate the mass of the Sun). The orbit of a star, S2, has been fully mapped out. Its period is 15.24 yr and semi-major axis length is 980 AU. Using...
