Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Enhanced resolution in cosmological simulations reveals new structure in the circumgalactic medium.
Neighboring exoplanets appear to come in similar sizes. But is this a result of observational bias?
Survival rates of Kuiper Belt Objects with binary companions are used to determine the history of the Solar System.
We can learn a lot about the history of the universe from the stars we see in the night sky today. In today’s astrobite, we look at the history that certain carbon-enhanced, metal-poor stars might be trying to tell.
