stellar particle IDs

Hi there,
I am wondering that whether a stellar particle IDs will also sometimes cease to exist? For gas particles, it can be promoted into black holes or stars and then, it ceases to exist. I don't know if stellar particle will turn into a black hole and stop existing.
Thanks,
David Wang

Hi David,

No, this shouldn't happen. Although stars lose mass with time, they are never completely removed from the simulation after they are formed.

Thanks for the reply! To be precise, I am thinking about some event such as supernova explosion. After that, will the simulation just delete this stellar particle?

Hi David,

No, this may involve the release of energy/mass near stars, but it won't ever destroy stars (this is because star particles represent entire populations, not just a single star which would explode and then be gone). You can find the details in the TNG methods papers.

Got it! Thank you!
