Fermi Arcs in an antiferromagnet detected at BESSY II
An international cooperation has analyzed samples of NdBi crystals, which display interesting magnetic properties. In their experiments including measurements at BESSY II, they could find evidence for so called Fermi arcs in the antiferromagnetic sta.....»»
Quasi-periodic oscillations detected in a long-period eclipsing dwarf nova
Using NASA's Transiting Exoplanet Survey Satellite (TESS), Chinese astronomers have detected quasi-periodic oscillations (QPOs) in the light curve of HS 2325+8205—a long-period eclipsing dwarf nova. The discovery was detailed in the January 2023 is.....»»
Small planets orbiting low-mass stars detected with the SPIRou instrument and the TESS satellite
Since the discovery in 1995 of a planet in orbit around a star other than the sun, research in exoplanetology has revolutionized our knowledge of planetary systems. The SPIRou instrument, installed at the Canada-France-Hawaii Telescope, contributes t.....»»
