Theoretical physicists modelled the region around M87's supermassive black hole, confirming that gravity plays a key role in accelerating particles out to thousands of light years. The findings provide further evidence for Einstein's theory of general relativity and its application to astrophysical phenomena.
The BICEP3 experiment has ruled out several popular inflation models, including some motivated by string theory. The findings suggest that the correct model will be slightly more complicated than those ruled out, but still offer a wide range of viable alternatives.
A research team from Göttingen University observed magnetic forces arranging gas particles in solar prominences, with charged particles moving at speeds of up to 42 km/s. This phenomenon is significant for understanding astrophysical processes, including star and planet formation.
A new study reveals how supernovae explosions of massive stars can form heavy neutron star binaries, resolving a puzzle from gravitational wave observatories LIGO and Virgo. The team's results show that the explosion energy determines whether a stripped star forms a neutron star or black hole.
Theoretical astrophysicist Kevin Heng has discovered an entire family of new mathematical solutions for calculating phase curves, enabling the analysis of data in seconds. These solutions have major implications for interpreting data, such as analyzing the Cassini spacecraft's Jupiter phase curves to infer a cloudy atmosphere.
A new study published in Monthly Notices of the Royal Astronomical Society found that superflares on red dwarf stars occur at high latitudes, near the star's poles, which means they are not directed towards orbiting exoplanets. This reduces the danger to planetary atmospheres and habitability.
Astrophysicists discovered that the TRAPPIST-1 system remains stable due to a 'resonant chain' configuration, where planets' orbital periods form simple ratios. This harmonic stability explains why the system has survived for millions of years.
Researchers from Lomonosov Moscow State University studied Keplerian shear flow stability, predicting turbulent behavior at high Reynolds numbers. They employed a variational approach to model non-ionized matter flows.
