What line on the HR diagram includes the sun?

The White Dwarfs are very hot stars, which are small in size and relatively dim. They are found in the lower left of the H-R Diagram. The Main Sequence is a band of stars, which includes most of the stars, like our Sun. These are usually smaller stars, often dwarf stars.

What is the main sequence of the HR diagram?

The group called the main sequence extends in a rough diagonal from the upper left of the diagram (hot, bright stars) to the lower right (dim and cool). Large, bright, though cool, stars called giants and supergiants appear in the upper right, and the white dwarfs, dim, small, and hot, lie in the lower left.

What stage of life is our Sun in on the HR diagram?

The Main Sequence: The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.

Where on an HR diagram would the very massive main sequence stars be?

The H-R Diagram More massive main sequence stars are hotter, and are found at the top left of the strip. Less massive stars are cooler, and are found at the bottom right.

Is the sun a main sequence star?

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars.

Where in the main sequence is the sun?

Because of these different types of fusion, stars on the lower main sequence last much longer than stars on the upper main sequence. Our Sun is located on the lower main sequence and is predicted to last between 10 and 12 billion years. A star located on the upper main sequence may only last a few million years.

Is the Sun a main sequence star?

What is the Sun’s life cycle step by step?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

Where is the sun on the H-R diagram quizlet?

Our own star, the Sun, is nearly in the middle of both the temperature and luminosity scales relative to other stars. This puts it around the middle of the diagonal line.

How will the location of the sun on the H-R diagram change when the sun becomes a red giant?

How will the location of sun on the H-R diagram change when the sun becomes a red giant? It will move to the cooler and brighter part of the diagram. Where are hot and very luminous stars shown on the H-R diagram? Where will a white dwarf star most likely be on the H-R diagram?
