This is the first neutron star in which an extended signal has been seen only in infrared light. The remarkable discovery was made by a team of international researchers who have offered two possible explanations for the extended infrared signal – a dusty disk or an energetic wind known as a pulsar wind.
Scientists observed an extended area of infrared emissions around this particular neutron star, which belongs to a group of seven nearby X-ray pulsars — nicknamed ‘the Magnificent Seven.’
Lead author of the study Bettina Posselt said one possible explanation is that there is a disk of material – most likely dust – surrounding the pulsar.
“Such a disk would be composed of matter from the progenitor massive star. Its subsequent interaction with the neutron star could have heated the pulsar and slowed its rotation,” Posselt said.
This phenomenon is known as supernova fallback disk, and if confirmed as the source of the signal it could change our general understanding of neutron star evolution, according to Posselt.
Another theory is that the emission was caused by a pulsar wind slamming into the neutron star as it sped through interstellar space. The shocked particles would then emit synchrotron radiation, causing the extended infrared signal that we see. read more…

Militants in Syria’s Idlib have transported several canisters containing chlorine to the village of Bsanqul, apparently preparing to stage a false flag chemical attack, the Russian Defense Ministry has said.
The chlorine-filled canisters were delivered by the Al-Qaeda-affiliated militants of Tahrir al Sham, formerly known as Al-Nusra Front, a spokesman of the Russian Center for Reconciliation in Syria, Lieutenant General Vladimir Savchenko, said in a statement Saturday. He added that the latest developments showed that the militants are preparing for a false flag attack that would be used to accuse the Syrian government of using chemical weapons against its people.
This is the latest warning from the Russian military on what it says is a chemical “provocation” in the making. On Wednesday, it said the White Helmets group has shot videos intended to be used in framing the Syrian government. Earlier, the MoD said toxic chemicals had been delivered Idlib and accused the White Helmets of carrying out the delivery.
The US and its allies have so far dismissed the Russian warnings, but said that the government in Damascus might instead be preparing chemical attacks against civilians. read more…
