If Astronomers observe a typical star using a telescope and a spectrometer they will be able to determine what?
i have no idea but it uytr
Can astronomers tell from the elements of a star what uts surface temperature is?
The temperature of a star is determined for it's colour spectrum. The hotter the star the more the spectrum is towards blue where as a cooler star has a spectrum closer to red.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
For nearby stars, the parallax method is used.
What property of a star would you use to determine what elements it can create?
I don't no why are you asking me
Which elements would be present in a star just before it forms a supernova?
Iron
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What would be a common task for astronomers?
using a telescope to determine the coordinates of a star
How star made of?
Our Sun is about 70% Hydrogen and 28% Helium by mass, with traces of heavier elements. Other stars can be a little different, but with a spectrometer, scientists are able to determine the elements that are present in any star.
What Elements Are Present In The Star Sirius?
Hydrogen and helium are the most abundant elements in a star.
How do scientists determine the element present in a star?
By the star's spectrum.
How do astronomers determine if a star is moving towards or away from us?
They use a tool called a SPECTROSCOPE.

How can astronomers determine whether a star is moving toward or a way from earth?
They can do so by examining the light from the star. Doppler shift can indicate this
What does the spectrum of a star determine?
Elements that exist in the start

How can astronomers infer which elements are are found in a star?
Atoms in a star's corona are subjected to extremely high levels of energy from the photosphere. This energy excites electrons in the atoms, and causes the electrons to jump up to a higher energy state. When the electrons fall back to their rest state, they emit photons at a very specific set of wavelengths unique to each element. By examining the wavelengths of light coming from a specific star (in a process called astronomical spectroscopy) astronomers are able to decipher with complete certainty which elements are present in that star. . For example, hydrogen emissions are known to occur at 410.2nm (violet), 434.1nm (violet), 486.1nm (blue-green), and 656.3nm (red). When a star is seen to emit a combination of those wavelengths, astronomers can be certain hydrogen is present in the star under observation. .
