What Does PMS Stand For?

PMS stands for Pre Main Sequence

PMS, or Pre Main Sequence, refers to the stage in stellar evolution prior to a star entering the main sequence phase of its life cycle. During this period, a young star forms from a collapsing cloud of gas and dust, accumulating mass and increasing in temperature. The PMS phase is characterized by significant changes in luminosity and size as the star stabilizes before beginning hydrogen fusion in its core. This stage is crucial for understanding stellar formation, development, and the eventual characteristics of stars.
