SUMMARY

Third generation stars in the Milky Way can be nearly as old as the universe, approximately 14 billion years. Supermassive Population III stars are capable of going nova in under 100 million years, while their offspring may have slightly longer lifespans. However, low mass stars, considered the "grandkids" of the first generation, can still exist today, contributing to the age estimation of nearly 14 billion years for some stars.

PREREQUISITES
  • Understanding of stellar evolution and lifecycle
  • Familiarity with Population I, II, and III star classifications
  • Knowledge of supernova mechanisms and their implications
  • Basic concepts of cosmic chronology and the age of the universe
NEXT STEPS
  • Research the lifecycle of Population III stars and their characteristics
  • Explore the implications of supernova events on stellar populations
  • Study the methods used to estimate the age of stars in the Milky Way
  • Investigate the role of low mass stars in galactic evolution
USEFUL FOR

Astronomers, astrophysicists, and students of cosmology interested in stellar formation and the history of the universe.

In the Milky Way?

Some could be nearly as old as the universe [~14 billion years]. Supermassive pop III stars could go nova in less than 100 million years. Some of their offspring could also have expired after a similarly brief existence [although not quite as quick as their metal free parents]. But low mass grandkids of the first generation could still be around - hence nearly as old as the universe.
