What is the H-R diagram?

Back

The H-R diagram (Hertzsprung-Russell diagram) is a scatter plot of stars showing the relationship between their absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.

What are the main stages in a star's life cycle?

Back

The main stages in a star's life cycle include: 1. Nebula, 2. Main Sequence, 3. Red Giant/Supergiant, 4. Supernova (for massive stars), 5. Neutron Star or Black Hole (for massive stars) or White Dwarf (for smaller stars).

Front

What is a white dwarf?

Back

A white dwarf is a small, dense star that is the remnant of a low or medium mass star after it has exhausted its nuclear fuel and shed its outer layers.

Front

What is a supernova?

Back

A supernova is a powerful and luminous explosion that occurs at the end of a massive star's life cycle.

What is the difference between a red giant and a supergiant?

Back

Red giants are larger and cooler stars that have expanded after exhausting hydrogen in their cores, while supergiants are even larger and more luminous, often resulting from the evolution of massive stars.
