The TESS mission has found an Earth-like planet in the habitable zone of its star, but the question of how the system formed is baffling astronomers.
Long-term space missions have left us with a wealth of stellar data. Come to Dr. Jennifer van Saders’s talk at #AAS235 to learn more about how these data, along with stellar models, can reveal a star’s evolutionary past and future.
All stars rotate, and stellar rotation can impact a star’s evolution greatly. However stellar rotation remains poorly understood. Can studying stellar pulsations shed light on this topic?
Is the gravitational constant really constant? Today’s authors investigate using an 11 billion year old star.
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
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.
