[U] Of Stellar Remnant "Fall-Back Disks": We Will Talk About This, In The Morning... Smile.


There's been a fascinating discovery in deep interstellar space, over the weekend. UPDATED: do go read all about it, at NASA.gov's Hubble page.

. . . .“One theory is that there could be what is known as a ‘fallback disk’ of material that coalesced around the neutron star after the supernova,” said Posselt. “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. If confirmed as a supernova fallback disk, this result could change our general understanding of neutron star evolution. . . .” A fallback disk, a warp of space-time proportions. I like that notion, as a metaphor, for various events, from this day in 2012 (could well have averted it all). A time machine of sorts. . . .



. . . .Indeed, it is whirling ever so gracefully, into the night, some nearly six billion years on. . . and anyone who would like to describe what we are seeing above, feel free to chime in (this will all change -- come morning). . . .

". . .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. . . ."


Yes do tune in -- in the morning as six years on, there is so much to say -- but silence is once again, the rule of the day. . . .for the story. Smile.
