Websystem. You will be asked to identify 14 “Unknown” stars based on their spectral properties. To do this, you will be given a list of “Reference” stars with various spectral types to be used as a basis for comparison. All the stars listed in this lab are members of a sub-classification called main sequence stars. WebThe least massive stars in the Universe are the red dwarf stars. These are stars with less than 50% the mass of the Sun, and they can be as small as 7.5% the mass of the Sun. This tiny mass is the minimum amount of gravitational force you need for a star to be able to raise the temperature in its core to the point that nuclear fusion can begin.
