Why are stars classified as Obafgkm?
Description of the spectral types (the labels OBAFGKM are called “spectral types” because the way to measure hydrogen in stars is to look at their spectra, or emission lines).
What are the 7 different spectral classes of stars?
The spectra of stars are described in terms of spectral classes. In order of decreasing temperature, these spectral classes are O, B, A, F, G, K, M, L, T, and Y. These are further divided into subclasses numbered from 0 to 9.
What is the rarest type of star?
The least luminous O-type stars can remain on the main sequence for around 10 million years, but cool slowly during that time and become early B-type stars. No massive star remains with spectral class O for more than about 5–6 million years.
What types of stars are the brightest?
The brightest Solar-type star in the sky is Alpha Centauri, which is very close to us. Alpha Cen is actually a double-star system we call a binary, but the brighter component is only a little larger than our own Sun.
Which stars are the coldest?
In general, a star’s temperature determines its color, from red to blue-white. Spectral types are named with a letter. The seven main types are M, K, G, F, A, B and O. M stars are the coldest stars and O stars are the hottest.
