For stars in the main sequence, which color of stars tend to have higher absolute brightness?
The HR diagram is shown with Absolute Brightness on the y-axis from negative ten to fifteen and Surface Temperature on the x-axis from 40,000 to 2,500 Kelvin. There are several dots plotted between ten and fifteen absolute brightness and 10,000 to 2,500 degrees Kelvin labeled Supergiants. There are several dots plotted between negative 1.5 and three absolute brightness and 7,500 to below 2,500 degrees Kelvin labeled Giants. There are several dots plotted between ten and fifteen absolute brightness and 30,000 to 15,000 degrees Kelvin labeled Dwarfs. Down the middle, there are several dots plotted diagonally from 40,000 and 2,500 Kelvin, and negative ten to positive fifteen are labeled Main Sequence.
a) White stars
b) Yellow stars
c) Blue stars
d) Red stars
