The oscillation modes of stars can tell us about their interior structure. However, strong magnetic fields can damp out these modes and make them undetectable. These authors look at two types of stars with oscillations to see what their magnetic fields are like.
Betelgeuse has captivated everyone’s attention by dimming significantly in 2019/2020 before returning to former brightness. Is the riddle really solved by dust or might there be another explanation? Is the star now entering its final stage before violently dying?
Today’s #UndergradResearch post by Joseph Guidry is all about searching for variable white dwarf stars!
The structure of oscillations in intermediate mass stars has eluded astronomers, until now.
What secrets are hiding in the archives of the GALEX satellite?
By the time a star becomes a white dwarf, much of its mass will have been lost. When does this mass loss occur and what drives it? Read today’s astrobite to find out.
