An Alternative to Planet 9: Maybe there is nothing special
Planet 9. Everyone’s favorite yet to be discovered planet; famously predicted to exist due to the aligned orbits of TNOs. Today’s paper explores the question, is a Planet 9 really the most likely scenario to explain these orbits?
Joint Survey Constraints for Cheap!
Constraining physical parameters in a cosmological survey is often computationally expensive, especially when considering more than one survey at a time. The authors of this paper offer a simple method to reconstruct parameter distributions in a fraction of the time needed for most high-performance computers.
Galaxy collisions and star-formation: a surprising causal examination
The longstanding role of galaxy mergers as drivers of star-formation is brought into question
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.
