the sun gets brighter and the temperature increases
No.
As the Sun ages, it will gradually increase in size, brightness, and temperature. This will cause the circle graph representing the Sun to shift towards the higher end of the scale in terms of luminosity and temperature, while the size of the circle may increase slightly. Eventually, the Sun will exhaust its nuclear fuel and evolve into a red giant, causing significant changes in the circle graph.
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.
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.
The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.

Yes, the sun is an average-sized star in terms of its size, temperature, and luminosity compared to other stars in the universe.

Sirius
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.
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.
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.
Sirius A and Procyon A are two stars that have similar luminosity and surface temperature. They are both main-sequence stars and are relatively close to each other in terms of these characteristics.
No, dwarf stars are smaller in size and mass compared to our Sun. They are classified by their lower luminosity and surface temperature.
