The temperature of a star can tell us how big or small the star is. We can also determine it's distance from earth and how old the star is and how bright the star is.
The hotter the star the shorter it's life is.
The hottest star in the universe is called a super hot blue giant and only have a life of a few million years as they burn their fuel quicker then any other star. At the end of this stars life it will go supernova.
Then there are red giants they are 20 times massive and 16000 times brighter then our sun also at the end if this stars life it to will go supernova.
Then there are yellow dwarf stars like our sun, this type of star has a life span of approx. 10 billion years. At the moment our sun is middle age at over 4.5 billion years old. Yellow dwarfs burn out at the end of there life and don't go supernova as they don't have a huge mass.
Then there are red dwarfs which are the most common stars in the universe. Red dwarfs burn cooler and are very fain. this type of star has the longest life and will be the last stars to die in trillions and trillions of years.
What else can I help you with?
What can a star's spectrum tell us?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
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.
Can astronomers tell from the elements of a star what uts surface temperature is?
Yes, astronomers can estimate the surface temperature of a star based on its spectral type, which is determined by the elements present in its atmosphere. Each spectral type corresponds to a range of surface temperatures, allowing astronomers to make an educated guess about a star's surface temperature.
What does the Doppler affect tell astronomers about a star?
The star attracts the planet; the planet attracts the star. As a result of the latter, the star changes position. If this change is such that the star moves away from us during one part of the planet's orbit, and towards us at another (or more generally, the star's speed towards us, or away from us, changes slightly), then this can be detected as a Doppler shift.
How is the sun different in size and temperature from a star?
It isn't. The sun is a star and there are others that are similar in size and temperature.
What temperature the star?
you can tell the temperature by its color
What can a star's spectrum tell us?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
How can you tell the temperature of a star?
by it's color
Can you tell the star closer to us?
The closest star to us is the sun.
What can the Doppler effect tell us about in astronomy?
It can tell us whether a star, or a galaxy, is moving towards us or away from us.
Why a stars color and brightness is important?
A star's color tells us it's temperature, and indirectly, can tell us a lot about it's size. It's absolute brightness (as opposed to it's apparent brightness) also helps us define the star.
How can spectrum tell us if an object is reflecting blue light from a star?
how can you tell if an object is reflecting blue light from a star
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.
What is a star's emission spectrum?
The emission spectrum of a star is the spectrum of frequencies for emitted electromagnetic radiation during the transition of an atom's electrons from a high-energy state to a low-energy state. The emission spectrum can differ depending on the temperature and composition of the star.
How do colors tell you about the temperature of a star?
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
IN main sequence stars what is the relationship between brightness and temperature?
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
What is the equivalent temperature on the celsius scale?
You need to tell us what temperature you want to convert - and from which temperature scale !
