What would be the approximate temperature of a star with a luminosity 100 times greatera than the sun?

A star with 100 times the luminosity of the Sun would likely have a surface temperature of around 11,000 to 30,000 degrees Celsius. This higher temperature is required to produce the increased energy output associated with the higher luminosity.

Does Rigel have a higher luminosity and a lower temperature the the sun?

No.

Does Rigel have a higher luminosity and a lower surface temperature than the sun?

Yes, Rigel has a much higher luminosity than the Sun, being around 120,000 times more luminous. However, it also has a lower surface temperature than the Sun, with a surface temperature of around 11,000 Kelvin compared to the Sun's temperature of approximately 5,500 Kelvin.

What is the approximate temperature of the sun?

The approximate temperature of the sun's surface is around 5,500 degrees Celsius (9,932 degrees Fahrenheit).

According to the Hertzsprung Russell Diagram what is the luminosity of the Sun?

The luminosity of the Sun is approximately 3.8 x 10^26 watts. This value is calculated based on the Sun's size and temperature, placing it as an average star on the Hertzsprung-Russell Diagram.

What is the approximate luminosity of a main-sequence star whose mass is one-tenth that of the Sun?

There's no single answer, since luminosity depends not only of mass but stage and temperature. However, most 0.1 Solar mass stars are going to be red dwarfs, so consider Wolf 359, a nearby star, as an example. It's about 0.09 Solar mass and its luminosity varies from about 0.0009 to 0.0011.

What star has a surface temperature 9000k and luminosity about 1 to 20 times greater than the sun?

Sirius

Which star has a higher luminosity and a lower surface temperature than the sun Rigel Bernard's star Alpha Centauri or Aldebaran?

Aldebaran has a higher luminosity and a lower surface temperature than the Sun. Rigel has a higher luminosity but a higher surface temperature than the Sun. Bernard's Star and Alpha Centauri have lower luminosity and higher surface temperatures compared to the Sun.

How is star luminosity measured?

A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.

What does an H-R diagram compare?

An H-R diagram compares the luminosity (brightness) of stars with their surface temperature. It helps classify stars based on their temperature and luminosity, allowing astronomers to study their characteristics and evolution.
