List the stages in the star’s life during which it most likely lost some of the mass it started with. How did mass loss occur in each stage?arrow_forwardWhat is the free-fall time of a 10 MSun main-sequence star?

Two stars in the same system might be born at the same time, but they will evolve at a different pace, depending on their _________. Transfer of material between two stars in the same system can be especially dramatic if one star is __________. When one star transfers mass to the remnant that is the other star, it can re-ignite fusion and produce what astronomers call a _________. If the accumulated mass causes the remnant to have a mass greater than ____________, it can explode violently. Astronomers call this kind of explosion a ________________.arrow_forward
- The Sun's mass is 2.0x1030 kg, its radius is 7.0x105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.7x103 km, what would its period be if no mass were ejected and a sphere of uniform density can model the Sun both before and after? 60.40 s Incorrect.

Use the formula that you derive to estimate the mass of hydrogen atoms that are converted into helium in the interior of the sun (LSun = 3.9 x 1026 W). (Note: the mass of a hydrogen atom is 1 mproton and the mass of a helium atom is 3.97 mproton. You need four hydrogen nuclei to form one helium nucleus.)arrow_forward
