Introduction • Supernova is the death of a massive star. • Supernova remnants are the leftover of a supernova. • There are 2 basic supernova explosions that we studied: Type 1a and Type 2 • Can you identify which explosion occurred by looking at the elements in the remnants? Kepler
Model SN 1006 • Type 1a White dwarf stealing matter from a companion star CAS A • Type 2 explosion of a single super-massive star (25 or more times the mass of our sun.)
Data/Methods Used ds9 to specify the area of which we wanted to get the spectrum, as shown left.
Data/Methods 2 • A spectrum is a chart of the number of photons collected at each individual energy. • Each of the elements gives off photons of a certain energy, and at that energy, we found a peak in the spectrum.
Data/Methods 3 • This I s a spectrum of W49B. • Used these to find out which elements were present in each SNR. By looking at the major peaks. • Determined by looking at the energy of photons collected (x axis)
Discussion/Analysis • Our idea of type 1a supernova explosion starts with light elements and ends with light elements. These elements would fuse into slightly heavier elements, but not super heavy ones. • Our idea of type 2 supernova explosion starts with heavy and light elements and ends with the next heavier element. The heavy elements will fuse with each other to form even heavier elements such as iron.
Conclusion • There is a relationship between the elements present in the SNR and the type of explosion it originated from.
Results 2 • The supernovae that went through a type 1a supernova explosion were RCW 103, G11.2-0.3, SN 1006 and SNR 0453-68.5. • The supernovae that went through a type 2 supernova explosion were W49B, CAS A, Kepler, and SNR 0519-69.0. • Tycho is one of the supernova remnant that did not go through type 1a or type 2 supernova explosion. We conclude that there are more than two types of supernova explosion.
