SUMMARY

The discussion centers on the L-LOG-SUN value displayed in the exoplanet database, which represents the logarithm of a star's luminosity measured in solar luminosities. Participants confirm that the "LOG" indicates a logarithmic calculation, specifically comparing the star's luminosity to that of the Sun. This clarification aids users in understanding stellar data more effectively.

PREREQUISITES
  • Understanding of stellar luminosity concepts
  • Familiarity with logarithmic functions
  • Knowledge of solar luminosity as a standard measurement
  • Basic navigation of exoplanet databases
NEXT STEPS
  • Research the concept of stellar luminosity and its significance in astrophysics
  • Learn how to perform logarithmic calculations in scientific contexts
  • Explore the structure and data types in exoplanet databases
  • Investigate the methods used for measuring solar luminosity
USEFUL FOR

Astronomers, astrophysics students, and researchers working with stellar data and exoplanet databases will benefit from this discussion.

On the exoplanet database they have a value which I am not familiar with, can anyone
help me understand what value they are displaying represents?

Luminosity ?
" compared to solar luminosity?

Does LOG mean they performed a logarithm?

see attached picture . Thanks/ bob

Yes---this is the logarithm of the star's luminosity, measured in solar-luminosities.
