“This particular neutron star belongs to a group of seven nearby X-ray pulsars nicknamed ‘the Magnificent Seven’ that are hotter than they ought to be considering their ages and available energy reservoir provided by the loss of rotation energy.”

This is the first neutron star in which an extended signal has been seen only in infrared light and the instrument was the Hubble Space Telescope. Neutron stars are incredibly dense residues after a massive supernova of an exploding star. Another name for neutron stars is pulsars because they rotate rapidly and emit time-variable light. This particular neutron star rotates every 11 seconds.
Bettina Posselt, Ph.D., Associate Research Professor of Astronomy and Astrophysics at Pennsylvania State and the lead author of a research paper about this unusual neutron star reports: “This neutron star belongs to a group of seven nearby X-ray pulsars nicknamed ‘the Magnificent Seven’ that are hotter than they ought to be considering their ages and available energy reservoir provided by the loss of rotation energy. We observed an extended area of infrared emissions around this neutron star — named RX J0806.4-4123 — the total size of which translates into about 200 astronomical units or approximately 18 billion miles.”
The researchers suggest two possibilities that could explain the extended infrared signal seen by Hubble.
— There is a lot of dust around the pulsar.
— Pulsar wind nebula produced when “particles are accelerated in the electrical field that is produced by the fast rotation of a neutron star with a strong magnetic field. As the neutron star travels through the interstellar medium at greater than the speed of sound, a shock can form where the interstellar medium and the pulsar wind interact. The shocked particles would then emit synchrotron radiation, causing the extended infrared signal that is illustrated in the video.” What is unique — pulsar wind nebulae are usually seen in x-rays, so if this is an infrared-only pulsar wind nebula, “it’s unusual and exciting,”says Dr. Posselt.
