What is the temperature of a protostar?
the color of the protostar is red
When the pressure and temperature of a nebula increases what is formed?
When the pressure and temperature of a nebula increase, it can lead to the formation of protostars. As gravity causes the nebula to contract and heat up, eventually nuclear fusion can begin at the core of the protostar, leading to the formation of a new star.
Explain why a protostar heats up internally as its gravitationally contracts?
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.
What must happen before a protostar will glow?
Before a protostar can start glowing, it must finish collecting enough gas and dust to trigger nuclear fusion in its core. This process requires the protostar to reach a temperature and pressure high enough for hydrogen atoms to fuse together, releasing energy as light and heat.
What is the force that turns a nebula into a protostar?
The force that turns a nebula into a protostar is gravity. As regions within a nebula become denser due to slight fluctuations in density, gravity pulls the surrounding gas and dust inward, causing the material to clump together. This process leads to the formation of a protostar as the collapsing material heats up and begins to accumulate mass. Once the temperature and pressure in the core become sufficient to initiate nuclear fusion, the protostar evolves into a main-sequence star.
What happens to the surface temperature and luminosity when gravity first assembles a protostar from a collapsing cloud?
As gravity collapses the cloud to form a protostar, the temperature and luminosity both increase. The increase in temperature is due to the compression of material, causing the protostar to heat up as energy is released. The increase in luminosity is a result of the protostar radiating this energy.
How are temperature and density affected when a protostar begins to collapse?
Both will increase.
Why does temperature increase more rapidly in a more massive protostar than in a less masive protostar?
because the jews said so
What is the temperature of a protostar?
the color of the protostar is red
What is the process by which a protostar is heated up to initiate nuclear fusion and become a star?
A protostar is heated up by gravitational forces causing it to contract and increase in temperature. Once the core reaches a high enough temperature and pressure, nuclear fusion reactions begin, releasing energy and making the protostar shine as a star.
When the pressure and temperature of a nebula increases what is formed?
When the pressure and temperature of a nebula increase, it can lead to the formation of protostars. As gravity causes the nebula to contract and heat up, eventually nuclear fusion can begin at the core of the protostar, leading to the formation of a new star.
If the dust cocoon around a protostar emits radiation most strongly at a wavelength of 30 microns what is the temperature of the dust?
The temperature of the dust in the dust cocoon around a protostar can be estimated using Wien's displacement law. At a peak wavelength of 30 microns, the temperature is approximately 100 K.
What happens after a nebula contracts and its temperature increases to 10million K?
After a nebula contracts and its temperature increases to 10 million K, it can start nuclear fusion in its core, becoming a protostar. The increase in temperature and pressure triggers the fusion of hydrogen atoms into helium atoms, releasing energy in the form of light and heat. The protostar will continue to evolve and eventually become a full-fledged star.
Explain why a protostar heats up internally as its gravitationally contracts?
As a protostar contracts under gravity, its gravitational potential energy is converted into kinetic energy, increasing the speed and temperature of the particles. This increase in kinetic energy results in collisions that generate heat. The protostar continues to contract and heat up until internal pressures and temperatures are enough to initiate nuclear fusion and establish equilibrium between inward gravitational forces and outward radiation pressure.
Why does a protostar heat up internally as it contracts?
A protostar heats up internally as it contracts due to the gravitational potential energy being converted into thermal energy. The collapse of the gas cloud causes an increase in density and pressure, leading to a rise in temperature at the core. This process eventually triggers nuclear fusion and marks the start of a star's life cycle.
How many degrees is a protostar?
A protostar does not have a fixed temperature in degrees like a fully formed star. It is in the process of forming and can have a range of temperatures depending on its size, mass, and stage of development.
Inside a prostar the nuclear fusion of hydrogen will begin when?
The core of the protostar reached an extremely high temperature
