Hubble Uncovers Never-Before-Seen Features Around a Neutron Star

Post by Dragon on Wed Sep 19, 2018 2:49 am

An unusual infrared light emission from a nearby neutron star detected by NASA’s Hubble Space Telescope could indicate new features never before seen. One possibility is that there is a dusty disk surrounding the neutron star; another is that there is an energetic wind coming off the object and slamming into gas in interstellar space the neutron star is plowing through.

This animation depicts a neutron star (RX J0806.4-4123) with a disk of warm dust that produces an infrared signature as detected by NASA’s Hubble Space Telescope.

The disk wasn’t directly photographed, but one way to explain the data is by hypothesizing a disk structure that could be 18 billion miles across. The disk would be made up of material falling back onto the neutron star after the supernova explosion that created the stellar remnant.

This is an illustration of a pulsar wind nebula produced by the interaction of the outflow particles from the neutron star with gaseous material in the interstellar medium that the neutron star is plowing through.

Such an infrared-only pulsar wind nebula is unusual because it implies a rather low energy of the particles accelerated by the pulsar’s intense magnetic field.

This hypothesized model would explain the unusual infrared signature of the neutron star as detected by NASA’s Hubble Space Telescope.
