Star Distribution - Types, Galaxies & Time

    Distribution Stars
AI Thread Summary
The discussion focuses on the percentage distribution of star types (O, B, M, etc.) within our galaxy and various galaxy types, such as globular clusters, and how these distributions evolve over time. Participants express interest in understanding the specific structures of galaxies and their evolutionary relationships. The HR diagram is mentioned as a tool for visualizing star distribution, but it does not provide percentage data. There is a call for resources or insights that can clarify these distributions and their changes over time. Overall, the conversation seeks to deepen knowledge about stellar classification and galactic evolution.

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.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
