What two properties of a star determine its luminosity?
The luminosity of a star is primarily determined by its temperature and size (or radius). A hotter star emits more energy than a cooler one, while a larger star has a greater surface area to emit light. The relationship between these properties is described by the Stefan-Boltzmann Law, which states that luminosity increases with the fourth power of the star's temperature and directly with the square of its radius. Together, these factors dictate the total energy output of the star.
What is the radius of a G2III star?
The radius of a G2III star can vary, but on average it is around 10 times the radius of the Sun. This class of star is typically larger and brighter than the Sun, but smaller than supergiant stars.
Which of these objects has the largest radius a 1.2M rm Sunwhite dwarf a 1.5M rm Sun neutron star a 3.0M rm Sun black hole?
The black hole with a mass of 3 solar masses has the largest radius among the objects listed. This is because the radius of a black hole is determined by its mass and the Schwarzschild radius formula, which dictates that the radius of a black hole increases with its mass.
What two characteristics of a star determine its luminosity?
The luminosity of a star is primarily determined by its temperature and size (or radius). A hotter star emits more energy than a cooler star, while a larger star has a greater surface area from which to radiate energy. Together, these factors influence the total amount of light and heat the star produces, defining its overall brightness as observed from a distance.
The mass of a star can be determined by studying?
binary star systems
What is the radius of a star?
The radius of a star is a measure of its size, typically expressed in units such as solar radii, where one solar radius is the radius of the Sun, approximately 696,340 kilometers (about 432,690 miles). The radius can vary widely among different types of stars, ranging from less than a third of the Sun's radius for small red dwarfs to more than 1,000 times the Sun's radius for massive supergiants. The radius is determined through methods such as observing the star's brightness, temperature, and spectral characteristics.
In what unit do I measure the radius of a star?
You can use kilometers. Or you can compare it to the radius of our Sun, and say, for example, "This star has 600 times the diameter [or radius] of our Sun."
Which star has a radius of 10 km?
That's the approximate radius of a neutron star, a.k.a. a pulsar.
Is Antares bigger than V382 Carinae?
Yes, Antares is larger than V382 Carinae. Antares is a red supergiant star, while V382 Carinae is a white hypergiant star. The size of a star is determined by its radius, and Antares has a larger radius compared to V382 Carinae.
Is the color of a star determined by its location in the galaxy?
No. The color is determined by the star's temperature, not location.

How many times larger is the sun than a star that has 0.1 solar radius?
The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.
Which of these objects has the largest radius a 1.2M rm Sunwhite dwarf a 1.5M rm Sun neutron star a 3.0M rm Sun black hole?
The black hole with a mass of 3 solar masses has the largest radius among the objects listed. This is because the radius of a black hole is determined by its mass and the Schwarzschild radius formula, which dictates that the radius of a black hole increases with its mass.
Do tires make any difference in a car's turning radius?
The cars turning radius is not determined by the brand of tire.
What is the radius of the star Rigel?
Rigel has a radius of about 78 solar radii or 0.363 AU.
