Where are stars that are in their giant or super giant stages located on the Hertzsprung Russell diagram?

Answer 1

Upper right

Answer 2

Stars that are in their giant or supergiant stages are located in the top right side of the Hertzsprung-Russell diagram, also known as the "red-giant branch" or "super-giant branch." These stars are typically large and luminous, with low surface temperatures.

Answer 3

Supergiants [See Link] are among the most massive of stars. The most luminous Supergiants are often classified as Hypergiants [See Link] they can have masses from 10 to 70 Suns and brightness from 30,000 up to hundreds of thousands times the Sun.

Because of their extreme masses they have short lifespans of 30 million years down to a few hundred thousand years.

A Super giant are among the most massive stars in our universe. In the Hertzsprung-Russell diagram they occupy the top region of the diagram. In the Yerkes spectral classification supergiants are class Ia (most luminous supergiants) or Ib (less luminous supergiants). They typically have bolometric absolute magnitudes between -5 and -12. The most luminous supergiants are often classified as hypergiants of class 0.

Aldeberan is the brightest star in the sky. Aldeberan is the tip of Taurus's horn. Aldeberan is the largest red giant, and you can fit, I think, about 100,000 Earths in its diameter.

Answer 4

Brightness is relative to a stars luminousity and the distance between the Earth and the Star.

From Earth Arcturus is the brightest with an apparent magnitude of −0.04 (The Sun in comparison is -26.73).

In absolute brightness, a supergiant in the same place as the Sun - apart from cooking us - will be about 20,000 times brighter.

Answer 5

Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.

Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun

Answer 6

Red Giant stars are above the lower right portion of the Hertzsprung-Russell diagram because they are low (comparatively) temperature, fairly long lived stars. The burn their nuclear fuel sparingly.

Answer 7

On a Hertzsprung-RussellDiagram, the stars that areof the largest radii arefound mainly towards the upperright. They are "supergiant stars".

Also, some supergiant stars are found around the centre of the upper region of the H-R diagram.

These diagrams are essential in astronomy. They help to show some of a star's fundamental properties.

Answer 8

The super-giant stars are above the Main Sequence, having higher luminosity, but burn through their nuclear fuel relatively quickly, and therefore are shorter lived. The exceptions are the red super-giants, which burn slower and are longer lived. They are above the right end of the diagram.

Answer 9

Supergiants are the most massive stars, occupy the top region of Hertzsprung-russell diagram . Supergiants can have 10 to 70 solar masses and luminosity up to hundreds of thousands times the solar luminosity and because of their large masses they have lifespan of few million years and may be less than this value .

Answer 10

The most massive main sequence star is Theta Orionis C, in the Trapezium Cluster. Spica is also a massive blue main sequence star. Stars like this would become stars like VY Canis Majoris, the largest star known, near the end of their lives.
