What is mass loss: Definition and 4 Discussions

Stellar mass loss is a phenomenon observed in stars. All stars lose some mass over their lives at widely varying rates. Triggering events can cause the sudden ejection of a large portion of the star's mass. Stellar mass loss can also occur when a star gradually loses material to a binary companion or into interstellar space.

    I Black hole merger question (effect of mass radiated away via gravitational waves)

    Hi I have two black holes 1 Sun mass each, when they merge a significant percentage of the mass is lost and is radiated away, so the combined black hole remnant is only, say, 1.8M. What is a behavior of the test body on an orbit far away from that binary? I assume that after some time...

    Mass Loss and Orbit Expansion

    I need help with d) and e). Currently how I've approached it is by using the fact that e=mc^2 and I can correlate this emission of light with loss of mass. Then I can use the formulas in a) to correlate this with da/dt. I'm struggling to figure out what the rate of energy loss is though.

    Nuclear Fission Energy and Mass Loss

    (112 x 8.36 + 122 x 8.51) - 235 x 7.59 = 190.89 MeV My question is what should I do about the incoming neutron on the left that starts the fission. My thinking is that it does not have any binding energy and therefore I left it out of the calculation. Is that correct? Thank you

    B Sun's Mass Loss: 4 Billion kg/sec from Sunlight & Ejected Particles

    Found out the sun loses 4 billion kg per second worth of sunlight in e = mc². How much mass does the sun lose per second if we include all particles that the sun ejects such as ions and neutrinos? (and, neutrons?)
