Does Taylor Swift sing about the Gorgeous interstellar medium?
In her song Gorgeous, Taylor Swift sings “you should think about the consequence of your magnetic field being a little too strong.” She must be singing about interstellar medium!
How to Un-squash a Galaxy
Does our galaxy look like an Advil, a NyQuil, or just a simple sphere? The simulations studied in today’s paper may have the answer.
Dust Does Not Follow Gas
Molecular clouds, where new stars are born, are made of two components: gas and dust. The gas is mostly hydrogen, and the dust is made of elements crucial for forming planets and people, like silicon and carbon. Today’s paper shows that these two components behave very differently in a simulated molecular cloud. This could have exciting consequences for the growth of dust and the formation of stars and planets.
Cosmic Rays Make for Windy Galaxies
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.
Sneak a peek on the cause of death of protoplanetary disks
Why do planetary disks fade away so fast? A leading candidate as villain in this story is turbulence. Using the combined strengths of sophisticated theoretical models and observations, we might be able to find out if this is true!
The effect of magnetic fields on star formation
Boss & Keiser examine how magnetic fields with varying initial conditions affect star formation.
