SUMMARY

The discussion focuses on the distribution of stars by type (O, B, A, F, G, K, M) within our galaxy and other galaxy types, such as globular clusters. Participants emphasize the importance of understanding how these distributions evolve over time and are represented in Hertzsprung-Russell diagrams. The conversation highlights the need for detailed insights into galactic structures and their evolutionary relationships. Key contributors, including mgb_phys, provide valuable input but do not fully address the specific data requested regarding percentage distributions.

PREREQUISITES
  • Understanding of stellar classification (O, B, A, F, G, K, M types)
  • Familiarity with Hertzsprung-Russell diagrams
  • Knowledge of galaxy types (e.g., spiral, elliptical, globular)
  • Basic concepts of galactic evolution and structure
NEXT STEPS
  • Research stellar population synthesis models to understand star distributions
  • Explore the evolution of different galaxy types over cosmic time
  • Study the impact of environmental factors on star formation rates in galaxies
  • Investigate advanced astronomical tools for measuring star types and distributions
USEFUL FOR

Astronomers, astrophysicists, and students interested in stellar classification, galactic structures, and the evolutionary dynamics of galaxies.

I'm quite interested in finding out the % distribution of stars (by type, viz. O,B,..,M), a) within our galaxy and b) within other galaxy types (ex. globular, etc) - and how these distributions change with time.

Can anyone sate my curiosity (or point me in the right direction) ?

Thanks mgb_phys for you input, but that's not exactly what I was looking for.

I would like to know the particular structures of galaxies, how they evolve and how they relate to other types during their period of evolution.
