Magnetic fields are believed to play an integral role in the formation of stars and protoplanetary disks. Today’s article took the one of the closest looks ever at the magnetic field around a baby star and unveiled its underlying structure.
Spirou often runs into fantastic adventures with his courageous, and sharp pet squirrel Spip. Their next adventure: a radial velocity spectrograph. What sophisticated technology is this? How does it work? What can it help us find?
The energy injected into galaxies from dying stars through supernovae plays an important role in how they evolve in a process known as feedback. However, cosmic rays generated by supernovae may be equally important in constructing a complete picture of galaxy evolution. The authors of today’s astrobite investigate this by producing hydrodynamics simulations including supernovae, cosmic rays, and magnetic fields.
Does the Sun shine in high-energy gamma rays? Apparently so, in the form of a halo surrounding itself. But certain features of this gamma-ray halo are perplexing.
Although magnetic fields exist virtually everywhere, we still do not know quite a lot about the role they play in the evolution of our Universe. On galaxy scales and larger, they can be difficult to observe, but may play a crucial role in how they evolve. Today’s astrobite discusses work done to try and understand how initially weak fields in the early Universe can affect galaxy evolution over time.
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.
