Dead stars are usually cold balls of material in empty space. A teaspoonful of white dwarf matter would weigh as much as an Elephant on Earth, as white dwarfs are actually the compressed remains of a star like our sun, shrunk down to the size of Manhattan. More massive stars that die compress into neutron stars, even denser, which actually bends the light that travels around it. A teaspoonful of that would weigh about as much as a small mountain. Then for stars with masses above 1.44 times that of the Sun in their prime, shrink down to black holes. Theoretically no volume and with huge masses, translating into infinite density and possible infinite gravitational force. The event horizon is NOT part of a black hole, rather, it's simply an imaginary sphere around the Singularity that guarantees death if breached. Don't try to meet one. You probably would die millions of times more often than travel into another universe.

One characteristic that is not used to classify stars is their specific location in the galaxy. While stars are classified based on properties such as temperature, luminosity, and spectral type, their position within the Milky Way or other galaxies does not play a role in their classification. Instead, classification focuses on intrinsic properties that relate to their physical characteristics and evolutionary stages.
Luminosity is the total amount of energy emitted by a star per second.
The four variables astronomers use to classify stars are temperature, luminosity, size or radius, and mass. By analyzing these properties, astronomers can determine a star's position on the Hertzsprung-Russell diagram and classify it into different spectral types and stages of stellar evolution.
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.

The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.

Of course, you can classify them in different ways. One important way to classify them is their mass; it is basically their mass that defines the star's evolution. But you can also classify them according to their temperature, radius, age, metallicity, etc.
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
you classify stars by color, temperature, size, composition, and brightness.
