Supernova Remnant Group By: Shakib Ahmed & Al Soedomo The Chandra Astrophysics Institute Lynn English High School
Introduction • How did we get here? • Stars go through the “circle of life” • Astrophysicists are trying to unravel their behaviors • They have made inconceivable progress!
Background • A star forms only if it has enough gravitational force • A star requires the process of nuclear fusion • Mass determines lifespan • Smaller stars live longer than more massive stars • At the end of a star’s life, it goes through supernova • There are two types of supernova • Type I (originates from white dwarf and companion star) • Type II (originates from supergiants) • Our solar system – possibly formed by a Type II supernova • Is there a relationship between the temperature and the elements in a supernova remnant?
Data/Methods • From ds9 we found: • Distance • Diameter • Flux • NASA website: • Composition • Two Models of SNR: • Expansion • Bomb explosion • Temperature • Hot object cooling
Results Comparing two SNR spectrums
Conclusion • So, is there a relationship between the temperature and the composition? • After collecting data, we saw that there was no relationship between the temperature and composition • We can’t predict the composition knowing the temperature • This method of finding the composition can be used when the data is taken right after a star goes supernova
