International team detects eruption of mega-magnetic star in nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none.
Eruption of mega-magnetic star lights up nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none.
Huge energetic flare from magnetic neutron star detected
Magnetars are among the universe's most extreme objects - a class of the compact stellar remnants called neutron stars that possess immensely strong magnetic fields. Once in a while, they produce enormous eruptions of gamma rays in the strongest nondestructive release of energy known in the cosmos.
For the three stars with detected astrospheres, named 70 Ophiuchi, epsilon Eridani, and 61 Cygni, the researchers estimated their mass loss rates to be 66.5±11.1, 15.6±4.4, and 9.6±4.1 times ...
