A good example of a medium size star is the Sun, which is very average. Luminosity is measured by the star's absolute magnitude, which is the magnitude seen from a standard distance of ten parsecs (32.6 light-years), and the Sun's absolute magnitude is +4.7. A factor of 100 increase in luminosity corresponds to 5 magnitudes less (larger magnitudes mean dimmer stars). The brightest stars have absolute magnitudes around -7.

If a star has a large luminosity and also a low surface temperature then it must have?

If a star has a large luminosity and a low surface temperature, it must have a large surface area to compensate for the low temperature and still emit a high amount of energy. This would make the star a red supergiant, a type of star that is both luminous and cool at the same time.

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 type of star has a high temperature and low luminosity in the HR diagram?

A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
