(Fahrenheit). "That amount of heat keeps the outer gas shell expanding while the ultra-dense core keeps from collapsing under its own gravity. The star is said to be in "equilibrium" or on the "main sequence". This is the point where a star spends most of its life." (Aspire.Cosmic-Ray.org‚ Stars‚ Main Sequence). If in the formation of a star not enough heat is generated in the core to begin a fusion reaction‚ it is known as a Brown Dwarf. The stars core burns different gases or materials‚ but soon

Science of Stars SCI/151 Abstract The information contained in this paper will explain the science of the stars. Other information in this paper will be a description of how astronomical instruments aid astronomers in determining the rotation rate of distant objects‚ speed‚ temperature‚ and composition. Also‚ the author will provide an explanation of the properties of stars in the Hertzsprung - Russell diagram. In conclusion‚ the complete lifecycle of the Sun will be explained‚ along

LIFE CYCLE OF A STAR Stars are formed in nebulae‚ interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries‚ dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released

Process and importance of fusion in stellar evolution. Huge clouds of hydrogen atoms and gravity cause the atoms to be attracted to each other creating them to slowly move towards the centre of mass.The atoms then continue condensing until something happens.All of the atoms are trying to get to the centre of mass. While this is happening the temperature becomes 10 million Kelvin and at that point there is enough temperature and enough pressure to overcome the coulomb forces‚ bringing the two protons

cool‚ dim‚ red stars at the lower right of the H-R Diagram to hot‚ bright‚ blue stars at the upper left corner of the H-R Diagram. The stars that fall into to this band are known as main-sequence stars. Stars such as the sun‚ and almost every start visible in the night sky fall within this band of main sequence stars. <br><br>There is another group of stars which are cool and bright that appear near the upper right corner of the H-R Diagram. These stars are very large and therefore have very big

transmitting of frame is required. It relies on packeting the frame queue to a definable window size which is provided to sender and receiver. Sliding window protocol defines maximum transmitter window size‚ Ws which is always one less than the sequence number. How transmitter window is defined: It is contains the data that are ready to be send. The lower limit in transmitter window which is waiting for acknowledgement is Slast .The upper limit frame in transmitter window is Slast + ws -1.Also

read in a FASTA format DNA sequence file‚ and parse out each sequence record into the part of ID and sequence. The ID is identified between the ">" and the "|" in the header line‚ and the sequence is the concatenation of all lines of the sequence part into a single string. Each DNA sequence record can then be stored into an array element of the DNA class. Use a loop in your program to prompt the user to enter a sequence ID‚ and if the ID exists print out the sequence. If the ID does not exist‚ print
