What part of a star is it that astronomers study in order to learn its characteristics of a star?
Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
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.
Does a star's spectrum show all of its elements?
The spectrum shows:the "blackbody radiation - a continuous spectrum that is related to the temperature of the surface of the starlines that are related to levels of energy that electrons jump, releasing photons, and"dark" lines which show energy levels of electrons belonging to elements in the atmosphere or the intervening space which block some radiation
If Astronomers observe a typical star using a telescope and a spectrometer they will be able to determine what?
Astronomers can determine the star's temperature, chemical composition, mass, luminosity, and age by analyzing its spectrum. By studying the absorption and emission lines in the spectrum, astronomers can also infer the star's motion, magnetic fields, and if it has any companions such as planets or other stars.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
Astronomers use the method of parallax to determine the distance to relatively close stars like Sirius. By measuring the apparent shift in position of the star as the Earth moves around the Sun, astronomers can calculate the star's distance based on trigonometry.
How do astronomers determine the chemical compositions of stars?
The answer is long and complicated, and it is too long to place here. You need to read an entire encyclopedia articles on spectroscopy and the chemical composition of intersteller objects. D.A.W.
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 instrument is used to tell what a star is made of?
Spectrometers are used for this. By looking at the spectrum of light coming from the star, scientists can tell which elements are in the star by the pattern of lines that are known to be associated with certain elements.
The set of spectral lines that we see in star's spectrum depends on the stars?
composition and temperature. The spectral lines correspond to different elements present in the star and the wavelengths of these lines are affected by the star's temperature. By analyzing these lines, astronomers can determine the chemical composition and other characteristics of the star.
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
Studying Fraunhofer lines helps to identify what on the stars?
Studying Fraunhofer lines helps identify the chemical composition of stars. These lines represent specific wavelengths of light that are absorbed by elements in a star's atmosphere. By analyzing the pattern of these lines, astronomers can determine which elements are present in the star.
What part of a star is it that astronomers study in order to learn its characteristics of a star?
Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
What does the spectrum of a star determine?
The spectrum of a star provides information about its temperature, composition, and motion. By analyzing the spectrum, astronomers can determine the star's chemical makeup, age, and even whether it is moving toward or away from Earth.
What instrument do the astronomers use to determine the chemical composition of the star?
MY ANSWER IS....SPECTROSCOPE....because stars can seen through spectroscope...:)) sorry kung ganito lang kasimple yung answer ko...im just a grade 6 pupil lang kasi.. nice to meet you all... -Dulce Dumapias...add me on facebook..ahaha:)) see you there..:))

What would be a common task for astronomers?
using a telescope to determine the coordinates of a star
How do astronomers know that hydrogen is present in almost every star in the universe?
Astronomers use spectroscopy to analyze the light emitted by stars. By studying the absorption lines in a star's spectrum, astronomers can identify the elements present in its composition. Since hydrogen leaves a distinct signature in these absorption lines, scientists have found that hydrogen is the most abundant element in stars, including our Sun.
