What are the three kinds of stellar spectra?

The first spectrum is a continuous collection of wavelengths from the radiation of a heated body. The second is a brightline emission spectrum illustrating the wavelengths a particular gas emits. The third is a darkline absorption spectrum showing the wavelengths that would be aborbed if the gas above were cooled.

What is the stellar classification spectrum?

Stellar classification is a systematic method used by astronomers to categorize stars based on their mass, temperature, and luminosity. The primary spectral classification system employs letters — O, B, A, F, G, K, and M — each representing a range of temperatures and characteristics of stars.

What are the 7 main spectral types of stars?

The 7 Main Spectral Types of Stars: O (Blue) (10 Lacerta) B (Blue) (Rigel) A (Blue) (Sirius) F (Blue/White) (Procyon) G (White/Yellow) (Sun) K (Orange/Red) (Arcturus) M (Red) (Betelgeuse)

What is the classification of stellar spectra?

Standard Stellar Types (O, B, A, F, G, K, and M) While the differences in spectra might seem to indicate different chemical compositions, in almost all instances, it actually reflects different surface temperatures.

What is the Harvard classification of stellar spectra?

Harvard spectral classification Physically, the classes indicate the temperature of the star's atmosphere and are normally listed from hottest to coldest. The traditional mnemonic for remembering the order of the spectral type letters, from hottest to coolest, is "Oh, Be A Fine Guy/Girl: Kiss Me!".

How to classify spectra?

Scientists often classify spectra based on the key light-matter interactions they represent and how they are used. Stars emit light, which travels out in all directions and interacts with other materials in space. The broad range of colors that a star emits depends on its temperature.

What are the classification of spectra?

There are 3 kinds of atomic spectra and they are emission spectra, absorption spectra, and continuous spectra.
