Ibix said:The "solar units" thing is telling you that mass is measured in terms of the mass of the Sun - such and such a star is seven times the mass of the Sun; M=7. The mass of the Sun is 1.
Can you take it from there?
A mass luminosity relation is a mathematical relationship between the mass and luminosity of a celestial object, such as a star. It describes how the mass of a star influences its brightness or luminosity.
Finding the constant of proportionality allows us to accurately predict the luminosity of stars based on their mass. This is essential for understanding the physical properties and evolution of stars, as well as for studying the larger structures and processes in the universe.
The constant of proportionality is determined through observations and measurements of a large sample of stars. This data is then used to create a mass luminosity graph, which can be used to find the slope of the line and thus the constant of proportionality.
Yes, the constant of proportionality can vary depending on the type and age of the star. For example, younger and more massive stars tend to have a higher luminosity for a given mass compared to older and less massive stars.
The constant of proportionality is a key factor in models of stellar evolution, as it helps us understand how a star's mass influences its luminosity and how this changes over time. By studying the constant of proportionality, we can gain insights into the life cycle of stars and how they evolve over billions of years.
