What is the classification for small hot stars?
Small hot stars are classified as type O, B, or A stars based on their spectral characteristics. These stars are typically blue-white in color and have high surface temperatures and luminosities. They are also referred to as main sequence stars because they are actively fusing hydrogen into helium in their cores.
Which color stars are hot?
Hot stars are typically blue or white in color. These stars have higher surface temperatures, often exceeding 10,000 degrees Celsius (18,000 degrees Fahrenheit). Their intense heat results in the emission of light at shorter wavelengths, which gives them their blue or white appearance. Examples of hot stars include O-type and B-type stars in the stellar classification system.
What spectral class is the hottest star under?
O. This is the class of the blue/white giants.
How do clusters of O and B stars compare to clusters of T Tauri stars?
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.
Is a blue star hot?
All stars are hot. Blue stars are the hottest.
What are the seven types of main sequence stars in the universe?
The seven types of main sequence stars in the universe are O (blue and hot), B (white-blue and hot), A (white and hot), F (yellow-white and medium), G (yellow and medium), K (orange and cool), and M (red and cool).

Are red stars hot or cool?
