Protostar - Wikipedia
A protostar is a very young star that is still gathering mass from its parent molecular cloud. It is the earliest phase in the process of stellar evolution. [1]
What Is a Protostar? The Birth of a Star - Biology Insights
The protostar phase concludes when the continuous infall of gas and dust ceases, and the object transitions into a pre-main-sequence star. For low-mass stars like the sun, this intermediate stage is known as the T Tauri phase.
Hubble Observes Stars Flaring to Life in Orion - NASA Science
This Hubble image features just-forming stars, called protostars, dazzle a cloudy landscape in the Orion Molecular Cloud complex.
Protostar – Definition & Detailed Explanation - Sentinel Mission
What is a Protostar? A protostar is a stage in the formation of a star where a dense cloud of gas and dust begins to collapse under its own gravity. This collapse triggers the process of nuclear fusion, which eventually leads to the birth of a new star.
Protostars Carve Out Homes In The Orion Molecular Cloud
Young protostars populate the cloudy regions in the Orion Molecular Cloud complex in these images from the Hubble Space Telescope. Three of the telescope's new images are part of a scientific ...
Protostars - Harvard University
The image below shows a very young protostar, still deeply embedded in its dust cloud. The star itself is the bright red spot near the base of the dark region. The bright spots above the star and strange spikes are artifacts in the image. Getting pictures of these objects is hard, because they remain covered in dust.
The Astrophysics Spectator:
As a protostar radiates, it shrinks in size to generate the energy that replaces the radiated energy. This shrinkage increases the self-gravity of the protostar, which is accompanied by an increase in the pressure at the protostar's core.
Glossary term: Protostar
Description: A protostar is an early stage in the star formation process. It is a large mass of gas and dust formed as a result of the contraction of a giant molecular cloud in the interstellar medium.
What is a Protostar ? - Universe Guide
A Protostar is the first stage of a star’s life after an event of some form has caused a nebula of dust and cloud to collapse. It has not yet built enough mass to fuse hydrogen to helium.
What is a Protostar? (with pictures) - AllTheScience
What is a Protostar? A protostar is a young star which is in the early stages of formation, before it reaches the main sequence stage. This stage of star formation can last 100,000 years or more, depending on the size of the star.
