Question
Wolf-Rayet stars have very strong stellar winds, losing as much as $10^{-5} M_{\odot}$ per year. If a typical Wolf-Rayet star is $20 \mathrm{M}_{\odot}$, what percentage of its mass might it lose in a million years?
Step 1
Mass loss per year = $10^{-5} M_{\odot}$ Mass loss in a million years = mass loss per year * 1,000,000 years Mass loss in a million years = $10^{-5} M_{\odot} * 10^6$ Mass loss in a million years = $10 M_{\odot}$ Show more…

An O star can lose 20 percent of its mass during its mainsequence lifetime. Estimate the average mass loss rate (in solar masses per year) of a $25-M_{\text {sun }}$ O star with a main sequence lifetime of 7 million years.
A red giant that was originally a 9.5 MSun main-sequence star loses a solar mass in 100,000 years via a superwind. What is this mass loss rate in units of solar masses per year? (The answer is not 0.000095 solar masses per year). Additionally, at this mass loss rate, what will the red giant's mass be after 0.5 million years? (Enter your answer as a multiple of MSun.)
A neutron star has a mass of $2.0 \times 10^{30} \mathrm{kg}$ (about the mass of our sun) and a radius of $5.0 \times 10^{3} \mathrm{m}$ (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a distance of 0.010 m? (Assume that the gravitational force is constant over the distance of the fall and that the star is not rotating.)
