The Gravitational Contraction Of An Interstellar Cloud Is Primarily The Result Of Its

As the gravitational potential energy decreases there is an increase in the kinetic energy in the form of heat and temperature. The core temperature of an object must reach a minimum temperature before the atoms inside will fuse. Our Sun along with most of the stars in our neighborhood probably formed. Start studying Astronomy Test 2. Gravitational contraction is the process of a clouds gravity overcoming its internal pressure and causing a collapse. The gravitational contraction of an interstellar cloud is primarily the result of its _______. Stars form when an interstellar cloud collapses under its own gravity heats and breaks into pieces of star-sized masses.

Learn vocabulary terms and more with flashcards games and other study tools.

A protostar is not considered a star until it gets its energy from nuclear fusion instead of gravitational contraction. Individual cloud fragments begin to collapse. A protostar is not considered a star until it gets its energy from nuclear fusion instead of gravitational contraction. An interstellar cloud of gas will remain in hydrostatic equilibrium as long as the kinetic energy of the gas pressure is in balance with the potential energy of the internal gravitational force. Mathematically this is expressed using the virial theorem which states that to maintain equilibrium the gravitational potential energy must equal twice the internal thermal energy. Interstellar cloud starts to contract probably triggered by shockpressure wave from nearby star.

Chapter 19 Section 2

The gravitational contraction of an interstellar cloud is primarily the result of its. Contraction of insterstellar cloud Solar system formed about 46 billion year ago when gravity pulled together low-density cloud of interstellar gas and dust called a nebula movie. 2 A small decrease in the stars internal pressure and temperature causes the stars outer layers to contract and heat up. The core temperature of an object must reach a minimum temperature before the atoms inside will fuse.

Parent cloud stage 1 contracting fragment between stages 1 and 2 emission nebula stages 6 and 7 cloud fragments Orion Nebula. An interstellar cloud of gas will remain in hydrostatic equilibrium as long as the kinetic energy of the gas pressure is in balance with the potential energy of the internal gravitational force. 3.

The interstellar cloud from which our Sun formed was thousands of times more massive than the Sun. 1 A small increase in the stars internal pressure and temperature causes the stars outer layers to expand and cool. At these optical wavelengths the cloud is completely opaque owing to extinction of background starlight caused by small interstellar dust particles that permeate the cloud.

Gravitational contraction is the process of a clouds gravity overcoming its internal pressure and causing a collapse. A typical protostar may be several thousand times more luminous than the Sun. Interstellar cloud starts to contract probably triggered by shockpressure wave from nearby star.

The resulting protostar which emits primarily infrared radiation is known as. Our Sun along with most of the stars in our neighborhood probably formed. Match ALL Of.

Cloud contraction M20 The Trifid Nebula evidence for three broad phases of star formation. The evolution of the protostar can be represented as a path on the Hertzsprung-Russell diagram. Sans radiation the collapse would cause the temperature to rise.

Sequence in which our solar system formed from a giant interstellar cloud of gas and debris. The gravitational collapse of a spherically symmetric interstellar gas cloud has been invest.
