How are Supernovae Ia and Dark Energy Related?

Click For Summary
SUMMARY

Supernovae Type Ia (SNe Ia) serve as standard candles due to their consistent peak brightness, which results from the detonation of a white dwarf after accumulating mass up to the Chandrasekhar limit. This property allows astronomers to measure cosmic distances accurately. The relationship between SNe Ia and dark energy is established through observations that reveal distant supernovae appear dimmer than expected, indicating the accelerated expansion of the universe driven by dark energy. This discrepancy in brightness correlates with redshift measurements, highlighting the significance of SNe Ia in understanding cosmic phenomena.

PREREQUISITES
  • Understanding of Supernovae Type Ia and their characteristics
  • Familiarity with the Chandrasekhar limit in astrophysics
  • Knowledge of redshift and its implications in cosmology
  • Basic principles of dark energy and its role in the universe's expansion
NEXT STEPS
  • Research the properties and mechanisms of Supernovae Type Ia
  • Study the Chandrasekhar limit and its significance in stellar evolution
  • Explore the concept of redshift and its measurement techniques
  • Investigate the role of dark energy in the universe's accelerated expansion
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in cosmology and the relationship between supernovae and dark energy.

Hey! I made a similar question in another post and it was really useful, but I'd like to learn more about this relation, and why the propieties of SNe Ia make them so special, so we can call them standard candels and how did they lead us to the discovery of Dark Energy.

Thank you!:smile:

Sn1a is easy. Mass accreates upon the white dwarf member of a binary system until it reaches the Chandreskar limit and detonates. The dark energy part arises because distant supernova are not as bright as predicted.
 
what would be, say, a table of sn1a redshift discrepancies that occur parallel to the dimness? would there be a dimness tabulation with that? or where could i find some?
sigh, .. relegated to library computers for a while
