What does the spectral type of a star measures what?
The spectral type of a star measures its temperature and determines its color, luminosity, and size. It is determined by the characteristics of the star's spectrum, such as the absorption lines caused by elements in its atmosphere. Astronomers use spectral types to classify stars based on their physical properties.
What are some characteristics used to classify stars?
In Astronomy stars can be classified by theircolor (temperature)composition (as found by their spectrum)agelocation in a galaxymassproximity to other stars
List 3 characteristics used to classify stars?
Stars are classified based on their temperature, luminosity, and spectral characteristics. Their temperature determines their color, ranging from blue (hotter) to red (cooler). Luminosity refers to the total amount of energy they emit, which helps categorize them into different classes. Spectral characteristics involve the analysis of light emitted or absorbed by stars, revealing their composition and aiding in classification into spectral types such as O, B, A, F, G, K, and M.
The spectral type of a star measure?
The spectral type of a star indicates its surface temperature and helps classify it based on the characteristics of its spectrum. It is determined by analyzing the patterns of absorption lines in the star's spectrum, which correspond to different elements present in its atmosphere. Spectral type is important for understanding the physical properties and evolutionary stage of a star.
What is spectral differentiation in remote sensing?
Spectral differentiation in remote sensing refers to the ability to detect and differentiate objects or features based on their unique spectral signatures or characteristics. It involves analyzing the reflectance or emission of electromagnetic radiation across different wavelengths to identify and classify different materials or land cover types. By examining the distinctive spectral responses of various substances, remote sensing technology can provide valuable information for applications such as land cover mapping, resource monitoring, and environmental assessment.
What two caracteristics of a star are plotted on the Hertzsprung-Russell diagram?
The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.

What does the hr diagram compare?
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.
What two star characteristics does the hertzsprung - Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective 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.
What are liners in astronomy?
A Low Ionization Nuclear Emission lineRegion (LINER) is a type of galactic nucleus that is defined by its spectral line emission.See link for more information
