How do size temperature and distance affect a star's magnitude or luminousity?
A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature. The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
How do astronomers use luminosity?
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.
What is Dschubba luminosity?
Dschubba, also known as Delta Scorpii, is a bright star in the constellation Scorpius. Its luminosity is approximately 1,500 times that of the Sun, making it a significant source of light in its region of the sky. Dschubba is classified as a blue giant star, which contributes to its high luminosity and temperature. Its brightness and position make it an important navigational star in the southern hemisphere.
Is the radius of a star increases how do you think it's Luminosity might change?
If the radius of a star increases, its luminosity is likely to increase as well, assuming its temperature remains constant. Luminosity is proportional to the surface area of the star and the fourth power of its temperature, as described by the Stefan-Boltzmann Law. Therefore, even a modest increase in radius can lead to a significant rise in luminosity. If the star also becomes hotter, the luminosity would increase even more dramatically.
What type of star has a high temp and high luminosity?
A star with high temperature and high luminosity is typically classified as a massive main sequence star, often of spectral type O or B. These stars have surface temperatures exceeding 30,000 Kelvin and emit vast amounts of energy due to their size and nuclear fusion processes. They are relatively rare and have short lifespans, often ending in supernova explosions.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
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.
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.

What two characteristics are stars classified by?
They are classified by the amount of Light they give off, and their temperature.
