Explaining Ancient Stellar Populations
Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
Subgiant in the spotlight: characterising a new benchmark star
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Making it Rain in the Circumgalactic Medium
Enhanced resolution in cosmological simulations reveals new structure in the circumgalactic medium.
Peas in a Pod?
Neighboring exoplanets appear to come in similar sizes. But is this a result of observational bias?
The Secret to a Steady Relationship in the Kuiper Belt
Survival rates of Kuiper Belt Objects with binary companions are used to determine the history of the Solar System.
Mixing up a Batch of Stars
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.
