Is there a maximum mass limit for stars in the universe?

Click For Summary
SUMMARY

The discussion confirms that while there is no strict theoretical maximum mass limit for stars, practical limits exist due to rapid burnout rates. Specifically, Population I stars have a maximum mass of approximately 100 solar masses, as their pulsations can disrupt the star. The upper mass limit in our region of the universe is estimated to be around 200 solar masses, with theoretical models suggesting that stars formed over 13 billion years ago may have reached masses close to 300 solar masses due to low primordial metallicity.

PREREQUISITES
  • Understanding of stellar evolution and lifecycle
  • Familiarity with Population I and Population II stars
  • Knowledge of supernova mechanisms and outcomes
  • Basic concepts of metallicity in astrophysics
NEXT STEPS
  • Research the characteristics and differences between Population I and Population II stars
  • Study the process of supernova formation and its implications for stellar remnants
  • Explore the role of metallicity in star formation and evolution
  • Investigate theoretical models of massive star formation in the early universe
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in the dynamics of star formation and the limits of stellar mass.

Is there a maximum mass a star can have?

Thanks

I don't believe there is a theoretical limit as such. However, there is a practical limit in that, the more mass a star has, the quicker it burns out. At that point it goes supernova and leaves behind something. This something could be a neutron star or a black hole, depending on size.

For Population I stars, the maximum limit is ~100 solar masses since the (normal) main sequence pulsations are so strong as to disrupt and disperse the star. For others, link where turbo-1 suggested.
 
There is an upper limit because at some point the star will ignite and the stellar wind will begin carrying off the outer protosphere. The upper limit is not firmly established, but, as turbo-1 noted, our region of the universe caps out at around 200 solar masses. Theoretical models suggest stars formed over 13 billion years ago could acquire even larger masses due to low primordial metallicity - approaching 300 solar masses.
