Seeing the interiors of massive A stars with TESS

Collaborators led by Tim Bedding at the University of Sydney published in Nature in May 2020 exciting new results from NASA’s TESS mission that are some of the first convincing identifications of the oscillations of a class of massive A stars that pulsate, named after the prototype star delta Scuti. The 2-minute cadence of TESS has finally allowed astronomers to identify the pulsations in delta Scuti stars, especially those that are young. Besides a NASA press release and a Nature News & Views for more general audiences, a thread contextualizing the discovery is here:
