Researchers at ISTA team present theoretical evidence that magnetic fields in stars can persist through all stages of evolution, emerging as 'fossil fields' at the surfaces of older remnants. This discovery sheds new light on our understanding of stellar magnetism and its relation to starquakes.
Scientists used multiple space-based instruments to track the evolution of a solar eruption, observing how it reduced background cosmic-ray activity. This approach has potential for improving space-weather forecasting and protecting satellites, astronauts, and power grids.
ISTA's Lisa Bugnet, Alicia Michael, and Marco Mondelli have been awarded ERC Starting Grants to develop new methods for extracting information from data, studying gene regulation, and understanding time-keeping in cells. Their projects aim to simplify data analysis, accelerate personalized medicine, and uncover the secrets of biologica...
Astronomers have created the first computer simulations showing how convection in the cores of massive stars generates waves that result in flickering starlight. The effect is different from the visible twinkling of stars in the night sky and could be observed with improved telescopes.
A study published in Nature Astronomy suggests that a volcano-like rupture on the surface of a neutron star could have caused its sudden slowdown. The research used X-ray data from orbiting telescopes to analyze the magnetar's rotation and found evidence supporting this theory.
Scientists have discovered a magnetic cycle in a distant star using stellar seismology, finding a pattern similar to the Sun's solar cycle. The study aims to better understand how magnetic activity cycles differ from star to star and its impact on potential planets.
