What type of stars did Leavitt discover had a relationship to their brightness?

  • Main Sequence Stars

  • Neutron Stars

  • Cepheid Variables

  • Red Giants

Answer

Cepheid Variables are a type of star that pulsates, or changes in brightness, over a regular period of time. Henrietta Leavitt discovered that there was a relationship between the brightness of a Cepheid variable star and its period of pulsation. This discovery was a key step in the development of the distance ladder, a method for measuring the distance to stars and galaxies.
