Question

3. Estimate the distance to a galaxy whose redshift indicates that it is moving away from us at a speed of 22,000 km/s. Assume that Hubble's constant is 22 km/s/Mly. 4. What is the mass-to-light ratio of a 30 $M_{sun}$ supergiant star with luminosity 300,000 $L_{sun}$? 5. The Milky Way Galaxy contains about 90 billion solar masses of material within the Sun's orbit, and the total luminosity of stars within that same region is about 15 billion solar luminosities. What is the mass-to-light ratio in our galaxy within the Sun's orbit?

Step 1

Hubble's law states that the recessional velocity of a galaxy is proportional to its distance from us. The formula for Hubble's law is v = H0 * d, where v is the recessional velocity, H0 is Hubble's constant, and d is the distance to the galaxy. Show more…
