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…
The authors of this paper pursued a mechanism which could possibly keep dead galaxies from forming new stars: mass ejected from AGB stars moving through the galaxy could heat the ambient gas.
Spherical cows have a long and storied history in physics, but does this type of crude approximation lead to realistic conclusions in the case of star formation? The combination of large- and small- scale simulations tests this idea.
How well do the current methods of measuring the star formation rate of galaxies match then known star formation rate in simulations?
