University of Sheffield What is a supernova Stellar explosions Types of supernova The importance of supernovae Supernova remnants Stellar explosions Most stars are a balancing act between gravity and pressure. Our Evolving Universe. 1. Atoms and Starlight. Why do the stars shine?. planets shine by reflected sunlight—but what generates the Sun’s light?. What does starlight tell us about the stars?. their temperature. Our Evolving Universe. 1. Introduction: The Night Sky. What do we see in the night sky?. the Moon. moving planets. occasional comets and meteors. against a background of randomly scattered “fixed” stars and the band of the Milky Way. Supernovae .

Our Evolving Universe. 1. Understanding Stars. What do we know?. From observations of nearby stars:. luminosity/absolute magnitude. colour/spectral class/ surface temperature. chemical composition. From observations of binary systems:. Our Evolving Universe. 1. Other galaxies. Telescopic images of the night sky reveal many other galaxies. What do they look like?. are they all like the Milky Way?. Where are they?. spread randomly through space, or grouped?. Array for Sub-. F. ermi . E. nergy . H. eavy Ion . R. eaction . D. ynamics.

Most stars either have M < 1.4 . M. ʘ. , . or can lose enough mass during post-main sequence evolution to get there, and end as white dwarf. However if core is more massive, nothing can stop gravitational collapse.
