Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in the star's temperature
What is the temp of high mass star?
Eta Carinae, with a mass 180 times that of the sun has a surface temperature of around 40,000 K. It is the hottest known star.
What determines a star's color in the Hertzsprung-Russell diagram?
Surface Temperature, and mass.
What is the parsecs of the bellatrix star?
The "Amazon" star, Bellatrix, has a surface temperature around 40,000*F and has a mass ten times greater than that of our sun!
How would an increase in mass affect the basic properties of a star?
As mass increases It increases the surface temperature , luminosity, and radius.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
What determines the temperature in the core of a star?
The star's mass determines the temperature in its core. A stars mass will also determined it size and the amount of gravitational pull it will have.
Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in the star's temperature
How diameter and absolute magnitude related?
the larger the mass of the star, the more luminous it is.
What makes stars colors different?
A star's color is determined by its surface temperature. This temperature is largely dependent on the star's initial mass.
What would be the absolute magnitude and color of a main sequence star with a luminosity of 100?
Absolute magnitude = -0.5Colour would depend on it's temperature.
What kind of star has an absolute magnitude of 10 and a surface temperature of 20000 K?
white dwarf.
What is the temperature of a high mass star?
30,000-52,000 degrees, Kelvin
What does and H-R diagram relate a star's temperature to?
The Hertzsprung-Russell diagram (H-R diagram) shows the relationship between absolute magnitude, luminosity, classification, and effective temperature of stars. The diagram as originally conceived displayed the spectral type (effectively the surface temperature) of stars on the horizontal axis and the absolute magnitude (their intrinsic brightness) on the vertical axis.
Why the temperature of the stars vary from one another?
The temperature in the core of a star depends, to a great extent, on:* The star's mass. The general tendency is that high-mass stars are hotter. * Where the star is in its life cycle. The star's core temperature will vary over time. On the other hand, the star's surface temperature also depends on its size. Thus, it is possible that PRECISELY because a star is hotter in the core, it gets bigger, and the surface temperature DECREASES (though its total energy output increases).
What would be the absolute magnitude and color of a main sequence star with a temperature of 25000K?
color: blue white
What does the HR diagram depict?
the relationship between a star's luminosity, temperature, absolute magnitude, and spectral type.
