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.
An interplanetary collision — in a distant planetary system
Interplanetary collisions can explain a number of phenomena in our own solar system — here’s evidence of such a crash shaping the formation of two distant planets. Translate from an Astrobitos bite by Elena Gonzales Egea.
That’s no exomoon… or is it? A careful evaluation of evidence for Kepler-1625b-i
Today’s authors carefully check their evidence for the first potential exomoon detection.
Looks like the Sun, but does it spin like the Sun: measuring differential rotation in 16 Cyg A & B
Today’s authors use asteroseismology to determine differential rotation in two sun-like stars.
Darwin’s Theory of Evolution, but make it planets
Can exoplanetary systems remain intact in dense stellar environments, or are their exoplanets destined to be flung into the far reaches of space? N-body simulations hint at characteristics that lead to a higher likelihood of survival.
The future is bright: a new technique finds variability in K2 data of the Seven Sisters
Today’s authors use a new technique to make new discoveries about the Seven Sisters.
