Henry Norris Russell and Ejnar Hertzprung?
Henry Norris Russell and Ejnar Hertzsprung were astronomers who independently developed the Hertzsprung-Russell diagram, which plots stars' luminosity versus temperature. This diagram is a fundamental tool for studying stellar evolution and classifying stars based on their characteristics. Their work laid the foundation for modern understanding of stellar physics.
What is the relationship between luminosity and temperature for main sequence stars?
On such a diagram, those stars lie on a curve called the "main sequence". It is not a simple relationship - for example, it isn't a straight line on the diagram. Therefore, it isn't easy to describe in words. It's best if you look up "Main sequence", for example on the Wikipedia, and look at the corresponding diagram.
What does main sequence mean?
The Hertzsprung-Russell diagram is a scatter graph of stars in which a star's luminosity (brightness) is plotted against its colour (temperature). Stars are not distributed all over this chart. A majority of stars lie on or near the diagonal which goes from top left (hot and bright) to bottom left (cooler and less bright). These are the main sequence stars.There are also white dwarfs which are below the main sequence whereas stars which are giants and super giants lie in the region above the main sequence.
Are main sequence stars hotter or cooler than the sun?
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.

A diagonal pattern on an H-R diagram where most stars lie is called?
The diagonal pattern on an H-R diagram where most stars lie is called the main sequence. This is where stars are fusing hydrogen into helium in their cores, representing the stable phase of a star's life cycle. The main sequence is a fundamental feature of stellar evolution and provides insight into a star's mass, luminosity, and temperature.

Type of stars in the H-R diagram?
The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot. Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.

How are stars on the upper left end of the main sequence different from those on the lower right end?
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
What are clusters of stars that all appear to lie at the same distance from us?
Clusters of stars that all appear to lie at the same distance from us are called star clusters. There are two main types: open clusters, which contain young stars and are loosely bound together, and globular clusters, which contain older stars and are tightly packed.
