Discussion Overview

The discussion revolves around the classification and evolutionary phases of stars, particularly focusing on red supergiants and black holes. Participants explore the characteristics of different stellar types and their transitions, touching on theoretical aspects of stellar evolution.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that black holes represent an interesting phase in the life cycle of a red supergiant star.
  • Others argue that black holes are not a phase of red supergiants, suggesting a different sequence of stellar evolution.
  • One participant mentions that supergiant stars can be of various colors, not just red, and emphasizes the sequence from supergiant to neutron star to black hole.
  • It is noted that Population III stars, which had zero metallicity, were supergiants, adding a historical context to the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the classification of stellar phases, particularly regarding the relationship between red supergiants and black holes. There is no consensus on the definitions or sequences presented.

Contextual Notes

Participants' claims depend on specific definitions of stellar phases and may involve assumptions about stellar evolution that are not fully articulated.

i say black holes are the most interesting phase of a red supergiant star.
 
Well, you could say that J20gU3, but black holes are not a "phase" of a red supergiant star.

u have start - can't mabe the next one - supergiant - red supergiant - nuteron star and if big enough black hole.
 
supergiant - red supergiant
No, no,... Supergiant stars are not necessarily red, they can also be white or blue. The sequence must be supergiant (whatever colour it has)-neutron star-black hole. It's interesting to know that the first generation of stars (Population III stars, that had zero-metallicity) were supergiants
