What is the luminosity of Betelgeuse?
Betelgeuse has about 140,000 times the luminosity of our sun or about 5.37×1031 watts.
What star has the surface temperature of approximatly 9000 k and luminosity 1 to 20 times greater then the suns luminosity?
There are millions of stars that fit that description. On the Main Sequence a star needs a spectrum of type A to be around 9000 degrees, and 1 to 20 times the luminosity of the Sun means an absolute magnitude in the range 1.2 to 4.7. For example Sirius.
Are main sequence stars all alike in their luminosity and temperature?
No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
What is the luminosity for the star Sheraton?
About 11 times the luminosity of our Sun which is about 4 x 10^33 (to the power of 33) erg/sec.
What is the lumnosity of alpha virginis?
The luminosity of Spica is 12100 times that of the sun.
What star has a surface temperature 9000k and luminosity about 1 to 20 times greater than the sun?
Sirius

What is a Polaris star luminosity?
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
Are main sequence stars all alike in their luminosity and temperature?
No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
Measurements indicate that a certain star has a very high luminosity 100000 times your sun but yet has a temperature that is cooler than the sun?
It could be a main sequence star.
Why is alpha centauri as luminosity 1.6 times that of the sun?
Alpha Centauri is as luminosity is 1.6 times that of the sun because it fuses hydrogen and helium in its core at a higher rate.
What is the luminosity for the star Sheraton?
About 11 times the luminosity of our Sun which is about 4 x 10^33 (to the power of 33) erg/sec.
What is the lumnosity of alpha virginis?
The luminosity of Spica is 12100 times that of the sun.
What is a star explosion which increases the star's luminosity to 1000 times that of nova?
A supernova.
Which of the following stars has a surface temperature of approximately 9000 K and luminosity about 1 or 20 times greater than the Sun's luminosity?
Don't write "the following" if you don't provide a list - it doesn't make any sense.
Is the star pollux already on the diagram of hertzsprung Russell?
Pollux is an orange giant star located about 34 light years from earth. It would no doubt have been used to help form the Hertzsprung-Russell diagram, showing temperatures of stars vs. luminosity. Its temperature is around 4865 Kelvin and it has a luminosity of 32 times that of our own sun.
