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?
Could the surface of Earth’s only natural satellite hold the key to understanding early activity of our own star? Today’s paper investigates the Moon’s composition to find out more.
There are a lot of Sun-like stars in the universe. Are they as identical as the name suggests, or are there important differences between them?
The Sun’s closest neighbor star Proxima Centauri—normally invisible to the naked eye—may have briefly become visible by increasing in brightness over 100 times for a few minutes back in 2016 in the largest flare ever seen from it.
Is it an exoplanet… or is it stellar activity in disguise? In today’s astrobite, we explore the stellar activity for a survey of M-Dwarfs, to help us distinguish signals of M-Dwarf stellar activity from the signals of the exoplanets that may be orbiting them.
How an exoplanet’s transits reveal starspots on HAT-P-11.
