Generally, the larger the star, the more luminous it is.

However, luminosity is measured as the visible light of a star as seen at the interstellar distance of 10 parsecs.

So a massive star could have a lower luminosity than a bright blue supergiant.

The bigger, the brighter. However, stellar class and temperature are just as important.

No. To determine a star's real brightness, its apparent brightness must be measured. Also, the star's distance must be determined through one of several methods.

What does HR diagrams tell us about a star?

Luminosity, heat, and location.


Is the star Betelgeuse luminous?

Yes, it is. Despite being 640 or so light years away from us, it is still one of the brightest stars in our sky, because of its huge size and luminosity.


Are nebulas brighter then stars?

Brightness is defined as a correlation between luminosity and distance. So it will depend on what is brighter and what is nearer to us.


How do you measure the distance to a cepheid?

Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance.Cepheids have a certain relationship between their period, and their absolute luminosity.

How does the color of a star indicates the chemical?

Different colors of stars can tells us the temperature of that star. It can also tell us the luminosity and mass of a star and where it is in its life cycle, whether it is a proto-star (new) or red super giant (dying high mass stars), or white dwarf (dying low mass stars). For more info, visit the link below in the related links.


What is the luminosity of the night sky. How much light do the stars produce relative to us compared to the sun?

The luminosity of stars varies quite a bit. Most stars (about 85-90% of them) emit less light than our Sun, while a few very massive stars emit, in extreme cases, over a million times as much light (or more precisely: total radiation) than our Sun.


The light from stars are used to determine what?

The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.


Why do astronomers study nebulae?

Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.


What informatoin can light revael about stars?

Stars' light tells us whether the star is moving toward us or away, it tells us the size of the star, and also the distance the star is from us. Stars light also tells us fairly accurately what different materials it is made of. (Usually hydrogen and helium). Light can also tell us if the star has about used up its hydrogen and so on.


Which is the smallest star in the us flag?

Since 1912 all stars are equal in size on the USA flag. Prior to that there were no regulations on the size or arrangement of the stars.


Does apparent magnitude refer to real luminosity?

No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.


What can electromagnetic spectrum tell us about a star?

Information that you can find about the star by looking at its spectra is its luminosity, surface temperature, its type(common/rare), color, how/if a star is moving, the density, the size, and future of the star. 2. And looking for spectral lines informs as to what elements are present.
