MIT astronomers have observed a wider swath of disk winds in the binary system Hercules X-1 for the first time.
Now, a team of MIT astronomers has observed a wider swath of winds in the binary system Hercules X-1 for the first time. This resulted in the creation of a two-dimensional wind map.It's a faraway system in which a neutron star is ejecting stellar material from a sun-like star. The warped accretion disk wobbles as it rotates around the system's centralAstronomers have had a difficult time studying disk winds. This is because they have only seen very narrow winds and not wider ones.
Disk winds have been observed most frequently in X-ray binaries. However, it has been unknown how these winds emerged from black holes or neutron star systems.Some experts theorize that magnetic fields could shred the disk, propelling material outward in the same direction as the wind. Others suspect that neutron star radiation is to blame for this phenomenon.How the winds were observed
The new map reveals information about the vertical shape, structure, and velocity of the wind . Researchers were able to determine the temperature and density of winds at various heights by measuring X-ray emissions. They discovered that the wind rises from the disk at a 12-degree angle. While winds were found to be colder and weaker at higher altitudes above the disk.
