What are the seven fundamental stellar spectral types?
The seven fundamental stellar spectral types are O, B, A, F, G, K and M. Also, what are their relationships to the stellar temperatures?
Who was the first person to classify stellar spectra by temperature?
Many people were involved in the current spectral classes.The person who first realised that the spectral sequence then categorised was in fact temperature, was Cecilia Payne.See related link for more information on her.
Stellar-classification?
Madalynne Braseltonstellar classification is the classification of stars based on their spectral characteristics
Which stellar spectral type has the largest number of prominent absorption lines in an optical spectrum?
M
Relate the stellar temperature to the classification of a star?
Stellar classification is based on the analysis of light from stars. The temperature from the photosphere of the star effects the amount and types of ions and this is used classifying the star.
What is stellar spectroscopy used for?
The purpose of stellar spectroscopy is to determine the chemical composition of stars, the temperature and some other characteristcs..
What are the four variables astromeners use to classify stars?
The four variables astronomers use to classify stars are temperature, luminosity, size or radius, and mass. By analyzing these properties, astronomers can determine a star's position on the Hertzsprung-Russell diagram and classify it into different spectral types and stages of stellar evolution.
Why is stellar evolution important?
hydrogen is what stars are mostly made Being the reservoir from which new stars are born in the Galaxy, interstellar matteris of fundamental importance in understanding both the processes leading to the formation of stars, including the solar system, and ultimately the origin of life in the universe. Stellar evolution stellar evolution is a necessary consequence of the physical theory of stellar-structure, which requires that the luminosity, temperature, and size of a star must change as its chemical composition changes because of thermonuclear reactions.ken mendozaPHIL.....
How do astronomers measure the temperature of stars and what methods do they use to determine this crucial aspect of stellar characteristics?
Astronomers measure the temperature of stars by analyzing the light they emit. They use a method called spectroscopy to break down the light into its different wavelengths. By studying the intensity of different wavelengths, astronomers can determine the temperature of a star. This crucial aspect of stellar characteristics helps astronomers understand the life cycle and behavior of stars.
How astronomers measure stellar temperatures?
Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.
What is the minimum temperature necessary for Stellar Nucleosynthesis to occur?
10 million kelvin
Do scientists use stellar parallax to determine a star's temperature?
No, scientists do not use stellar parallax to determine a star's temperature. Stellar parallax is a technique used to measure the distance to stars by tracking their apparent shift in position as the Earth orbits the Sun. A star's temperature is typically determined by analyzing its spectrum, which provides information about the star's composition and temperature through features such as absorption lines.
