Low-mass stars are much more common than massive ones. But massive stars outshine the smaller ones a thousand to one! How can astronomers account for this hidden majority? Maybe alcohol will help…
The process of star formation is exciting. During the early phases, a protostar undergoes two characteristic collapses. Today’s Astrobite explains the two collapse phases and briefly discusses their effects on the “final” product: the second core.
Galaxies die—at least when measured by how vigorously they produce stars. What causes them to die?
Molecular clouds are turbulent. Today’s paper explores how this fact affects the relationship between star formation rate and density from local clouds to distant galaxies.
Advanced observational tools such as ALMA allow the detection of complex organic molecules – the building blocks of life. However, how and where they are formed is still unknown.
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.
