What else can I help you with?
Why do stellar spectra have absorption lines?
Need a different, better answer.
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.
When was Stellar Occasion created?
Stellar Occasion was created in 1994.
What spectra are used to analyze stars?
The spectra of the stars you want to analyze.
How can forensic scientists use emission line spectra and absorption spectra?
Forensic scientists can use emission line spectra and absorption spectra to analyze trace evidence, such as glass fragments or paint chips, found at a crime scene. By comparing the spectra of the collected samples with reference spectra, scientists can identify the chemical composition of the evidence and link it to potential sources or suspects.

How did astronomers in the 19th century gather information about the chemical composition of stellar objects?
There is one way for gathering information about chemical composition of stellar objects - spectral analysis! Astronomical spectroscopy began with Isaac Newton's initial observations of the light of the Sun, dispersed by a prism. He saw a rainbow of colour, and may have seen absorption lines. The absorption lines in stellar spectra can be used to determine the chemical composition of the star.
