To determine

The complete formation process of the star.

Expert Solution & Answer

Explanation of Solution

Introduction:

The process through which thicker regions within molecular clouds in interstellar space collapse to form stars is referred to as star formation process. Stars represent the most basic bricks of galaxies. The formation and distribution of elements such as carbon, nitrogen, and oxygen are due to the stars.

The formation of a star can be understood by a study of the interstellar medium. The interstellar medium is mainly composed of 70% hydrogen by mass. The formation of clouds is in the dense regions of the interstellar medium. These molecular clouds are known as nebula where the stars are born.

At very low temperatures, the gases bind together to form molecules clouds. The cold regions inside molecular clouds also cause the gas to lump to high densities. When the desired density is achieved, stars form.

The formation of a star is due to the collapse of the cloud core in the denser region under their own weight/gravity. The centers are thicker than the outer cloud. So, they collapse first. As the core collapses, they fragment forms lumps. These lumps then combine to form into the protostar. A protostar continues to collapse to form star as long as the gravitational energy is balanced by the pressure due to the nuclear fusion reaction in the core.

Conclusion:

Therefore, the complete formation process of the star is studied in astronomy by observing and analyzing the behavior of interstellar medium and molecular clouds without even see the entire star formation process.

Select all of the statements about the main sequence stage in the life of a star that are TRUE: All stars spend the majority of their lives in the main sequence stage. Most stars lose a significant amount of mass while they are on the Main Sequence. Different stars spend a different amounts of time (number of years) in the main sequence stage, depending on the characteristics they were born with. Main sequence stars are rare in the Galaxy, so we are lucky to be living around one. During the main sequence stage, energy to power the star is provided by the fusion of hydrogen.

For a main sequence star with luminosity L, how many kilograms of hydrogen is being converted into helium per second? Use the formula that you derive to estimate the mass of hydrogen atoms that are converted into helium in the interior of the sun (LSun = 3.9 x 1026 W). (Note: the mass of a hydrogen atom is 1 mproton and the mass of a helium atom is 3.97 mproton. You need four hydrogen nuclei to form one helium nucleus.)

Place the following events in the formation of stars in the proper chronological sequence, with the oldest first and the youngest last. w. the gas and dust in the nebula flatten to a disk shape due to gravity and a steadily increasing rate of angular rotation x. a star emerges when the mass is great enough and the temperature is high enough to trigger thermonuclear fusion in the core y. the rotation of the nebular cloud increases as gas and dust concentrates by gravity within the growing protostar in the center z. some force, perhaps from a nearby supernova, imparts a rotation to a nebular cloud y, then z, then w, then x z, then y, then w, then x w, then y, then z, then x z, then x, then w, then y x, then z, then y, then w MacBook Air on .H.
