sing the HR diagram provided in this module (download the JPG file), find the absolute magnitudes for seven Main Sequence stars of temperatures 25000 K, 10000 K, 8000 K, 6000 K, 5000 K, 4000 K, 3000 K.
As explained in the video, find the Kelvin temperature, for a given star, on the horizontal upper axis, then move down from that point to the Main Sequence, then move right to the vertical absolute magnitude axis and read off the absolute magnitude.
Make a table with two columns. Kelvin temperature on the left and absolute magnitude on the right. Seven stars.
You will use these temperatures and absolute magnitudes in the next project, to find the distances to stars of certain apparent magnitudes that I will assign. Apparent magnitude is a measure of the amount of a star’s light that enters the telescope. The absolute magnitude is a measure of the total power radiated by a star in all directions.
