Astronomers Map Colossal ‘Disk Winds’ in Hercules X-1

Kosec et al. mapped the winds associated with the accretion disk around Hercules X-1, a binary system located 6,600 parsecs (21,526 light-years) away in the constellation of Hercules. Image credit: Jose-Luis Olivares, MIT / D. Klochkov, ESA.

Hercules X-1 is an X-ray binary system in which a neutron star is drawing material away from a Sun-like star. This neutron star’s accretion disk is unique in that it wobbles as it rotates. By taking advantage of this wobble, astronomers have captured varying perspectives of the rotating disk and created a 2D map of its winds. Kosec et al. mapped the winds associated with the accretion disk around Hercules X-1, a binary system located 6,600 parsecs...

Astronomers from the ACT Collaboration used NSF’s Atacama Cosmology Telescope to create this new map of the dark matter; the orange regions show where there is more mass; purple where there is less or none; the typical features are hundreds of millions of light years across; the whitish band shows where contaminating light from dust in our Milky Way Galaxy, measured by ESA’s Planck satellite, obscures a deeper view.
