What does protostar mean?
A protostar is a large, luminous ball of gas in the early stages of star formation. It is a critical phase in the life cycle of a star, marking the transition from a giant molecular cloud to a main-sequence star. Protostars are characterized by intense radiation and high temperatures, making them visible from millions of light-years away. The formation of a protostar is a complex process that involves the collapse of a giant molecular cloud. Protostars are often studied in the context of astrophysics and cosmology, providing valuable insights into the early universe and the formation of stars. The study of protostars has led to a greater understanding of the life cycle of stars and the role they play in shaping the universe.
nounA protostar is a large, luminous ball of gas in the early stages of star formation, before it has reached the main sequence and has begun to sustain nuclear fusion in its core.

Etymology of protostar
The term 'protostar' is derived from the Greek words 'proto-' meaning 'first' and 'star' meaning 'star'. It was first coined in the 1960s to describe the early stages of star formation. The term has since been widely adopted in the field of astrophysics and cosmology to describe the critical phase in the life cycle of a star.
Usage notes
The term 'protostar' is often used in the context of astrophysics and cosmology to describe the early stages of star formation. It is a technical term and is not commonly used in everyday language.
