1000 times more in what? Temperature? Volume? Mass? Diameter?
I assume you mean temperature since you have that word in the question. The core temperature of the Sun is about 15,000,000° C (27,000,000° F). So by multiplying which ever number you prefer by 1000 you get 15,000,000,000° C (27,000,000,000° F)
0.05 x 0.5 x 0.1 x 10000 = 25
True
Alcor is a hot, white A5V main sequence star having a luminosity about 13 times that of the sun. The spectral type implies that Alcor has an effective temperature of 8500 K, a diameter 1.7 times that of the sun, and a mass of about 2.2 solar masses. Alcor is a variable star of Delta Scuti type; see Caph.
No, white dwarfs are cooler than supergiants, they also have a lower luminosity (are more faint). A different viewpoint: There's obviously a range of temperatures for these stars, but the hottest (surface temperature) known star is in fact a white dwarf. It has a surface temperature of over 200,000 degrees Celsius.
Yes, though the sun would appear as only a very bright star from those distances, with the light levels on the surface being very low. The light received by Pluto would be around a thousand times less in terms of watts per square meter.
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.
10000 times hotter! That is your answer.
10000 times 10000 equals 100000000.
Very!! It is about 66,000 times more luminous than our Sun
10000 times 59345 is 593,450,000
100000000
100 times 100 = 10000
People can blink 10000 times a day.
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.
Assuming main sequence stars - the temperature would be about 15,000 Kelvin.
462 * 10000 = 4,620,000
10000 * 234 = 2,340,000
