What happens when a star condenses?
Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to heat up and start to glow forming Protostars.
What are being formed after the formation of stars?
The leftover material from the star’s birth is used to create planets and other objects that orbit the central star. Observing star formation is difficult, because the dust is not transparent to visible light.
What is formed when the core of a star is heated?
Once the temperature reaches 15,000,000 degrees Celsius, nuclear fusion takes place in the center, or core, of the cloud. The tremendous heat given off by the nuclear fusion process causes the gas to glow creating a protostar. As it glows, hydrogen is converted into helium in the core by nuclear fusion.
Where do stars form and why quizlet?
Stars are born in cold, relatively dense molecular clouds. As a cloud fragment collapses under gravity, it becomes a rapidly rotation protostar surrounded by a spinning disk of gas in which planets may form.
What element is stars made of?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
How are stars formed in the Solar System?
In this article we explain the process of star formation for regular Sun-like stars. Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars.
How long does it take for a star to form?
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.
What causes gases to clump together to form stars?
At these temperatures, gases become molecular meaning that atoms bind together. CO and H2 are the most common molecules in interstellar gas clouds. The deep cold also causes the gas to clump to high densities. When the density reaches a certain point, stars form.
What causes clusters of young stars to form?
Often in galaxies we find clusters of young stars near other young stars. This phenomenon is called supernova induced star formation. The very massive stars form first and explode into supernova. This makes shock waves into the molecular cloud, causing nearby gas to compress and form more stars.
