Undergrad Determining stellar mass independent of its gravity

Click For Summary
SUMMARY

This discussion focuses on methods for determining stellar mass independent of gravitational effects. Participants explore various research avenues and emphasize that all methods ultimately relate back to the solar mass. The conversation highlights the challenge of finding alternative techniques for measuring stellar mass without relying on gravitational influence.

PREREQUISITES
  • Understanding of stellar astrophysics
  • Familiarity with mass measurement techniques
  • Knowledge of solar mass as a standard unit
  • Basic concepts of celestial mechanics
NEXT STEPS
  • Research alternative methods for measuring stellar mass, such as spectroscopic analysis
  • Explore the role of stellar evolution in mass determination
  • Investigate the use of photometry in assessing stellar properties
  • Study the implications of mass measurements on galaxy formation theories
USEFUL FOR

Astronomers, astrophysicists, and researchers interested in stellar dynamics and mass measurement techniques.

Ultimately, all roads will lead back to the solar mass.
That from a previous thread.
Of yours.

And round and round we go.

I remember that with galaxies :) Just wanted to see if something different might turn up with a single celestial object.

K, L X-rays would certainly ionize atoms. https://www.scientificamerican.com/article/whats-the-most-distant-galaxy/ The James Webb Space Telescope has found the most distant galaxy ever seen, at the dawn of the cosmos.
