Deriving Angular Resolution from Bolometric Flux, Spectral Type & Temp

Click For Summary
SUMMARY

To derive angular resolution from bolometric flux, spectral type, and effective temperature of a star, one can utilize the limb-darkened diameter formula found in the referenced Springer paper. This formula connects the bolometric flux and effective temperature to the star's diameter. Additionally, lunar occultations may provide practical observational methods to measure angular resolution. Understanding these relationships is crucial for astrophysical studies involving stellar observations.

PREREQUISITES
  • Bolometric flux measurement techniques
  • Limb-darkening effects in stellar astrophysics
  • Effective temperature calculations for stars
  • Understanding of lunar occultations as observational methods
NEXT STEPS
  • Study the limb-darkened diameter formula in detail from the provided Springer paper
  • Research methods for measuring bolometric flux in stars
  • Explore effective temperature determination techniques for various spectral types
  • Investigate the application of lunar occultations in measuring angular resolution
USEFUL FOR

Astronomers, astrophysicists, and students studying stellar characteristics and observational techniques will benefit from this discussion.

If we know the bolometric flux, spectral type, and effective temperature of a given star, how can we derive the angular resolution from the information?

This was brought up in class and I've found myself obsessing since I can't figure it out.

I've found formula (3) of this page that gives the limb-darkened diameter of a star given its bolometric flux and effective temperature
http://aa.springer.de/papers/8331002/2300619/sc5.htm
Perhaps you know some formula relating the angular resolution with the limb-darkened diameter...

How about using lunar occultations? Here's a link.
