What is the most reliable way to measure the mass of a star for which the distance is known?

Question

Quizplus · Accepted Answer

Measuring the orbit of a star around another massive object (such as another star or a black hole) using Kepler's laws allows us to calculate its mass, as the mass of the object it is orbiting around can be determined through other means (such as measuring its own orbit). This method is particularly useful for binary star systems or for stars with companions that can be observed. The other methods listed (mass-luminosity and mass-temperature relations, and calculating mass from radius and density) are less reliable as they depend on assumptions about the star's properties and may not be accurate in all cases.
