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.
Traits of Accreting Galaxies
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
The Stuff of Stars
I attempt to summarize what some astronomers have called “undoubtedly the most brilliant Ph.D. thesis ever written in astronomy.”
Two Solar Tornadoes Observed with IRIS
Today’s undergraduate research post features a student who analyzed the motion of tornadoes on the Sun’s surface using spectroscopy. Read on to find out more!
Gravitational Redshift and the Pup: Measuring the Mass of Sirius B
Measuring a white dwarf’s gravitational redshift can help us figure out its mass, but for one of the closest stars to us (Sirius B) the numbers didn’t match with other methods. Today’s paper investigates the discrepancy.
One (solar system) catalogue to aid them all
Based on colour alone, can we distinguish between a rocky, icy and gaseous planet?
