Difference between Stellar classification and White dwarf

Stellar classification vs. White dwarf

In astronomy, stellar classification is the classification of stars based on their spectral characteristics. A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter.
