I got a question today for Planetary Radio Q&A that I couldn't answer, being pretty ignorant about solar system formation research. Can anybody help?
QUOTE We know from the metal composition of our solar system that the Sun is at least a second or third generation star. It made me wonder if it was possible that some of the comets or other KBOs that we witness might be from the Sun's predecessor star or stars. If not, could such bodies exist a bit further out? I should think it would be fantastic to be able to investigate such objects. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I got a question today for Planetary Radio Q&A that I couldn't answer, being pretty ignorant about solar system formation research. Can anybody help? That's not your run-of-the-mill Q&A inquiry, Emily. Is this, by chance, a grad student asking? I'm working off dim memory but I believe Jane Luu and David Jewitt did some work a few years ago on the survival of Kuiper belts over the main sequence lifetime of central stars. I believe they (or someone else) came up with estimates on the sizes of given belts and the amount of material that would survive the clearing phases of stellar evolution. I'll try and track down a reference. |
