What is the relationship between the color and the temperature of star?
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
What affects the brightness of stars?
The brightness of a star is primarily determined by its size, temperature, and distance from Earth. Larger, hotter stars tend to appear brighter, while stars that are closer to us also appear brighter due to their proximity. Other factors such as the star's age and its stage in the stellar lifecycle can also influence its brightness.
A star whose brightness changes?
A star who's brightness changes is called a variable star.Examples are:AlgolPolarisBetelgeuse.See related link for more information.
Give two reasons why the stellar magnitude might be confusing?
You have two main categories of magnitude. Apparent magnitude is how bright a star appears to be when we look at it. Different stars appear to have different levels of brightness. However all of the stars are different distances away. So a very bright star might be so far away that it looks very faint while a star that is not actually as bright as it appears far brighter because it is much nearer to us. Absolute magnitude measures the real brightness of stars, or how bright they would be if they were all the same distance from us.
The H-R diagram shows the relationship between a star and acirc and 128 and 153s surface temperature and its?
The Hertzsprung-Russell (H-R) diagram illustrates the relationship between a star's surface temperature (or color) and its luminosity (or absolute brightness). Stars are typically plotted on this diagram with temperature decreasing from left to right, and luminosity increasing from bottom to top. The position of a star on the H-R diagram indicates its stage in the stellar lifecycle, with main sequence stars, giants, and white dwarfs occupying different regions. Thus, a star's temperature and luminosity provide insights into its size, age, and evolutionary status.

What is it called when a star suddenly flares up?
A Nova. The colossal explosion of a very large star at the end of its life is a Supernova.

What units are stellar distances expressed in?
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.

What is the relationship of planets and stars with solar system galaxies and the universe?
Most planets orbit stars forming stellar systems. Stars are not part of the solar system which is simply the stellar system for our star - otherwise known as the sun. Stellar systems together form galaxies and these form a part of the universe.
How is tycho's supernova important?
Tycho's supernova which he saw in Casseopia was important, as its suddenness and brightness caused him to study astromomy for the rest of his life. That resulted in many contributions to the modern understanding of stellar objects.
What stellar property has the greatest range in values?
The stellar property with the greatest range in values is luminosity. Stars can vary dramatically in brightness, from extremely faint red dwarfs with luminosities significantly lower than the Sun to massive, luminous supergiants that can be millions of times brighter. This vast range reflects differences in stellar size, temperature, and evolutionary stage. Consequently, luminosity serves as a key indicator of a star's characteristics and lifecycle.
What is the significance of the mass-luminosity relationship in understanding the behavior of stars?
The mass-luminosity relationship helps us understand how a star's mass influences its brightness. This relationship is crucial in predicting a star's behavior, such as its energy output, lifespan, and eventual fate.
