  title: Types of Stars
  description: Major stages and classifications of stars.
  summary: "The main kinds of stars and stellar remnants with a description and a well-known example: main sequence stars, red giants, white dwarfs, neutron stars, black holes and supergiants, plus red and brown dwarfs, variable stars, pulsars, magnetars, Wolf-Rayet stars and binaries."
  use_when:
    - You need to classify a star or follow the stages of stellar evolution.
    - You want an example object for each type.
  caveats:
    - "These are overlapping categories, not a single sequence: a pulsar is a kind of neutron star, and a star can be both a binary and a variable."
    - Brown dwarfs are not true stars because they never sustain hydrogen fusion.

data:
  - type: Main Sequence
    description: Stars fusing hydrogen in their cores, including the Sun.
    example: Sun, Sirius
  - type: Red Giant
    description: Late-stage star that has expanded and cooled.
    example: Betelgeuse
  - type: White Dwarf
    description: Compact remnant of a low- or medium-mass star.
    example: Sirius B
  - type: Neutron Star
    description: Extremely dense remnant after a supernova.
    example: Crab Pulsar
  - type: Black Hole
    description: Object with gravity so strong that light cannot escape.
    example: Sagittarius A*
  - type: Supergiant
    description: Massive, luminous star nearing the end of its life.
    example: Rigel
  - type: Red Dwarf
    description: A small, cool, dim main sequence star; the most common kind in the galaxy and very long-lived.
    example: Proxima Centauri
  - type: Brown Dwarf
    description: An object between a planet and a star in mass that never sustains hydrogen fusion.
    example: Luhman 16
  - type: Variable Star
    description: A star whose brightness changes over time; Cepheids are used to measure distances.
    example: Delta Cephei
  - type: Pulsar
    description: A rapidly rotating neutron star that emits beams of radiation seen as regular pulses.
    example: Crab Pulsar
  - type: Magnetar
    description: A neutron star with an extremely strong magnetic field that powers bursts of high-energy radiation.
    example: SGR 1806-20
  - type: Wolf-Rayet Star
    description: A very hot, massive star shedding its outer layers in a strong stellar wind.
    example: WR 104
  - type: Binary Star
    description: Two stars bound by gravity and orbiting a common center of mass.
    example: Sirius A and B
