Black holes colliding, gravitational waves riding through space-time - and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers from the University of Zurich have now found that LISA could also shed light on the elusive dark matter particle.
Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.
Most red dwarf stars have planet families but are prone to violent outbursts, making their planets less hospitable to life.
The universe's deep past is beyond the reach of even the mighty Hubble Space Telescope. But a new review published in Frontiers in Astronomy and Space Sciences explains how creation of the first stars and galaxies is nevertheless being mapped in detail, with the aid of computer simulations and theoretical models -- and how a new generation of supercomputers and software is being built that will fill in the gaps.
According to new research, an object named GRB150101B -- first reported as a gamma-ray burst in 2015 -- shares remarkable similarities with GW170817, the neutron star merger discovered by LIGO and observed by multiple light-gathering telescopes in 2017. The new analysis, published on Oct. 16, 2018 in the journal Nature Communications, suggests that these two separate objects may in fact be directly related.
Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new record for the most extreme range of orbits yet observed: the outermost planet is more than a thousand times further from the star than the innermost one, which raises interesting questions about how such a system might have formed.
An international research team discovered the first recorded 'ultra-stripped supernova,' a rare, faint type of supernova that is believed to play a role in the formation of binary neutron star systems. These findings will advance our understanding of a wide variety of topics ranging from gravitational waves to the origin of precious metals like gold and platinum.
Ever since Chris Fox was a young boy, he wanted to visit alien planets. With no immediate plans for such a voyage, the Western University graduate student has done the next best thing. He's gone and found one.
Carnegie's Anthony Piro was part of a Caltech-led team of astronomers who observed the peculiar death of a massive star that exploded in a surprisingly faint and rapidly fading supernova, possibly creating a compact neutron star binary system. Piro's theoretical work provided crucial context for the discovery.
The unexpectedly gentle death of a massive star suggests that it was being robbed by a dense companion lurking out of sight.
