Sep 26, 2018 at 19:10 | comment | added | HDE 226868♦ | @JustinThyme So, the O star I talk about there likely has a mass of $\sim30M_{\odot}$, and losing half a solar mass would be a mere pittance. For an AGB star, it's possible that the mass loss rate would change from one time to another, but keep in mind that AGB stars are expected to lose around half of their mass over the course of their time on the branch ($\sim10^4$ years), so I think you're okay. | |
Sep 26, 2018 at 18:46 | comment | added | Justin Thyme | Any idea if the fact that the O star becomes increasingly smaller would have any effect on the loss rate, or is the AGB wind effect independent of star size? | |
Sep 26, 2018 at 18:38 | comment | added | Justin Thyme | I think I could live with 100,000 years, but it would be on the extreme limit. A bit of hand waving away the inconvenient facts, and I could probably get away with calling it 10,000 years or so. | |

Added in timescales.

Sep 26, 2018 at 17:46 | comment | added | Justin Thyme | Since it turns out that the mass loss is the same for any planet in any star system, and the solution (50% loss) would apply equally throughout the galaxy, there is no requirement for the answer to be limited to our system. | |

Sep 26, 2018 at 17:15 | comment | added | HDE 226868♦ | @JustinThyme I'm glad. I'm going to add some new calculations soon, talking about the necessary timescales to lose the amount of mass you want. | |
Sep 26, 2018 at 17:14 | comment | added | Justin Thyme | I appreciate your time and effort to repost, as I had your answer in mind when I posited this new question. | |
Sep 26, 2018 at 17:11 | comment | added | HDE 226868♦ | As a note: This is a modification of a section of my answer to your other question. I removed the part there about mass-loss rates and have transferred it here, with some particular modifications. | |
