Star formation and supernova explosions play an important role in galaxy formation and evolution, in a process known as feedback. Today’s astrobite discusses how modifying the amount of feedback from supernova explosions affects the properties of the disc of a Milky Way galaxy, and how it affects the hot, gaseous halo surrounding massive galaxies.
More than 50 years ago, a Norwegian astronomer named Sjur Refsdal outlined an interesting new method for calculating the Hubble constant. Last November, astronomers found the perfect test case.
Dark matter, in the form of primordial black holes, can potentially trigger Type Ia supernovae in white dwarfs.
White dwarfs in a binary often merge into a variety of interesting phenomena. However, nobody has sought to understand the role that magnetic fields play during the merger. The authors simulate the merging of two white dwarfs with magnetic fields to see what happens.
A supernova goes off. A star has died. Can its partner have anything to do with it?
Stars formed in the early Universe were extremely massive and extremely low in elements heavier than helium. The transition from the first to the second generation of stars is still hidden in the shadows of the past. However, simulations of the most massive supernovae can help us to decipher the way of how the life cycle of stars came into being.
