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.
Stars form via gravitational collapse of molecular cloud cores. But observations reveal that far less gas is turned into stars than you would suspect by naively calculating the star formation rate. So what can we do about this mismatch?
The first stars may have formed in clusters, rather than in isolation as previously thought. What would these clusters look like?
Reproducing the observed star formation history of galaxies in simulations is a fantastic test of our understanding of galaxy evolution. This is regulated strongly by “feedback”, for example, from supernova. Today’s astrobite discusses feedback from high mass X-ray binaries.
Magnetic fields are a crucial part of star formation. Read on whether and how the magnetic field strength dissipates during the early collapsing phase.
Are more massive stars more likely to have planets? Read on to find out…
