When stars reach their final stage, some explode as a consequence of nuclear reactions occurring inside the core. The stellar explosion is called the supernova which is divided into physical types: the Type I and Type II. They are basically classified according to their luminosities and spectral lines. Type II supernovas have lesser peaking of maxima in contrast to Type I supernovas. They also die abruptly. Maxima is equivalent to 10 billion luminosities. When it comes to spectral lines, Type [...]

Photo by: Chrkl Creative Commons Supernovas are explosions towards the end of the life of a star. They are classified as supernova I and II, depending on their solar luminosities. Type I supernova has a peaked maxima (about 10 billion luminosities) and then gradually disappears. Type I supernova is further divided into Type Ia and Type Ib based on the spectra it emits. All type I’s do not have hydrogen lines. Here we will focus on Type Ia which shows [...]
