Hubble Has Discovered Rare Features Around a Neutron Star

The well-known Hubble Space Telescope has discovered a rare infrared light emission around a nearby neutron star which could indicate new features never before seen. One probability is that there is a dusty disk surrounding the neutron star; another is that there is an energetic wind that slamming into gas in space.

With the word of scientists although neutron stars are generally studied in radio and high-energy emissions, such as X-rays, this study reveals that new and interesting information about neutron stars can also be gained by studying them in infrared light.

The observation with the help of a team of researchers at Pennsylvania State University, University Park, Pennsylvania; Sabanci University, Istanbul, Turkey; and the University of Arizona, Tucson, Arizona can better understand the evolution of neutron stars. Neutron stars are also called pulsars because of their very fast rotation (typically fractions of a second, in this case 11 seconds).

To better understand what is Neutron stars keep going reading.

Hubble official site explains very clearly. [Imagine crushing more than 50,000 aircraft carriers into the size of a baseball. This describes neutron stars. They are among the strangest objects in the universe. Neutron stars are a case of extreme physics produced by the unforgiving force of gravity. The entire core of an exploded star has been squeezed into a solid ball of neutrons with the density of an atom’s nucleus. Neutron stars spin as fast as a blender on puree. Some spit out death-star beams of intense radiation — like interstellar lighthouses. These are called pulsars].

“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,” said Bettina Posselt, associate research professor of astronomy and astrophysics at Pennsylvania State and the lead author of the paper. “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 (approximately 18 billion miles) at the assumed distance of the pulsar.”
