Zombie Star

On August 6th, 1181 AD a new star arrived in the constellation of Cassiopeia (the giant W in the northern skies) and was recorded as a guest star by Chinese and Japanese astronomers of the day.

The star stuck around for 6 months before vanishing from view, and never to be seen again, until now.

When Amateur astronomer Dana Patchick came across what looked like a planetary nebula in 2013, his 30th such find, he named it Pa30, but later observations have not only shown it to be a supernova, but its age is around 850 years and matches the location recorded by those astronomers back in 1181.

But what really surprised astronomers wasn’t just finding the remnants, but what lay at the center, an apparent white dwarf, but at 200,000’c and 130 times brighter than the Sun, with a wind of 16,000 kps, almost 5% the speed of light.

White dwarfs just don’t do this, and even the most energetic stars Wolf Rayet’s don’t do this, leading astronomers to describe the star as a “Whacko weird thing!”

Astronomers think it was similar to a Type 1a supernova, where a white dwarf companion pulls in material from its companion star, building up mass until it passes the Chandrasekhar limit (about 1.4 M☉)and collapses and causes a supernova, usually igniting both stars in the process.

However, in that case, the original white dwarf collapses to a neutron star, and Pa30 does not contain a neutron star.

What happened was a much rarer SN1ax, exactly the same mechanism, except somehow the white dwarf survives the explosion in a much-diminished state, blowing off most of the remnants material into space, but leaving behind the superhot core.

 

I don’t think that he’s the same Klaus who comments on this blog – BUT – have any of you seen both of them at the same party?  …I thought not.

 

Bullet Points:

** Ah, the English, winning hearts and minds again…BBC

Mrs Newey wanted her mother’s headstone inscription to read: “In ár gcroíthe go deo” (“In our hearts forever”). But a judge said untranslated, this may “be seen as a political statement”.

“Given the passions and feelings connected with the use of Irish Gaelic, there is a sad risk that the phrase would be regarded as some form of slogan or that its inclusion without translation would, of itself, be seen as a political statement,” said Judge Stephen Eyre, QC, chancellor of the Diocese of Coventry.

Untranslated Irish words would be “unintelligible to all but a small minority of readers”, he ruled in his judgment for the Church of England consistory court on 6 May.

** (The Hill) MOSCOW – “What are you, really, playing the fool? When will the contracts be?” Putin said, appearing visibly agitated in the video. “Here’s what I’m talking about. Directors of enterprises tell me: There are no contracts. And you have ‘everything done.’”

The Russian military supply system is faltering as logistics are not readily available at the Ukrainian front. When you consider that the countries adjoin, there is no lengthy supply train from Russia. The material just isn’t there.

** Looking back to the invasion of Iraq.

Saddam operated on the gold standard. While there were no weapons of mass destruction, which the Bush White House knew when it ordered the attack, they did find gold.

** Mayor of Kingstown – Season 2 – I didn’t think that much of Season 1, though the acting was good. Maybe 2 will be better. It appears that Jeremy Renner will recover from his injuries in the snow plow accident at his home. I wish him the best.

** In the Bleak Midwinter

** Your sentence – death by vaccination? Almost a thousand political prisoners are being held in the Federal Prisons in Brasilia. The men were sent to Papuda prison, the women to Colmeia penitentiary. “Upon arrival, they are vaccinated against Covid (probably against their will), given a rolled-up mattress without a pillow and a hygiene kit”, Brazil in English wrote.

** I give a lot of credit to Musk and SpaceX.

** Electric Car Mod.  Make it a hybrid. I realize that hybrids don’t satisfy the Green Lobby, but they make sense if you want to go that way.

  1. Um.

    Electric cars *do* charge the batteries, whenever the car is decelerating.

    This purported system, which apparently charges the batteries while under acceleration, only serves to make the system less efficient, using more electricity to accelerate the car. Perpetual motion, still not a thing.

    Not that I’m a fan of electric cars, but they are not _that_ stupid.

    -Kle.

    • They’re not stupid. They work. A hybrid system that includes a gasoline engine makes more sense to me and I’d be more inclined to throw money in that direction than to rely on the charging systems available out in the market – or a really LONG extension cord.

      • I’m with you. A hybrid is probably the best you’re going to get in over 90% of the real world. If you had to run on gas those last miles to a gas station, you’re more likely to find gas than a recharging station.

        The way the guy wrote that Tweet (I assume) about the abortion hanging off that Chevy Bolt shows not a clue about things like conservation of energy, thermodynamics, or a whole bunch of other things.

        • +1 There is no such thing as a free lunch. The person with the Chevy Bolt is trying to disprove that and will fail, probably badly. I am looking at gas/electric hybrids but if you keep your cars for a long time like I do when you consider battery replacement costs it is not that great a deal. You can buy a lot of gas for $5-8K.

          Gravestone. Good of you to point out that freedom of speech, even constrained as it is becoming in the US is a critically important right. So does this mean that any epitaphs on a gravestone has to go through a government approvals process? Boy wouldn’t that be a great job for a bureaucrat.

  2. There was a homemade hybrid that used an Opal GT frame, a five horsepower gas engine that ran a generator, and the starting motor from a jet to drive the wheels.
    Plus a battery pack. Read an intro about it, but not much since then.

  3. I wonder how many headstones in the UK have untranslated, say, Arabic or Mandarin phrases on them. And curious to know the legal status of those grave markers.

    • Today, Islam can’t be touched in the UK. Even whispering a word out of place is proof in court. Irish, on the other hand, is a filthy and subversive language that must be stamped out with extreme prejudice.

  4. The “Guest Star” defined as a “Whacko weird thing” that leaves after six months…sounds like anyones odd uncle on their mothers side, altho the start actually left after a time.

    Wonder where all that gold went to? Congress pushed the WMD false narrative.

    EV Mods- Perpetual Motion machines we knew in Junior High wouldn’t work but drew them up anyway. EV owners fail one critical aspect in the physics department, you do not create energy, only transfer it from one source to another.

    Renner- Happy he’s home…talk about massively fortunate. I’m glad he and his family are being tight-lipped about details…reports (for what those are worth) he lost his leg, hopefully those were false. He has a long road to recovery, but the man is a warrior.

    • Note to self: Quit commenting with the iPad. Correcting my incoherence: “…,altho the STAR actually left after a time whereas the weird uncle may stay indefinitely if not given the shove after a week.”

  5. British Headstone- I get it, it’s England, maybe it’s some weird law (who would care?). But since TPTB have gone off the rails I have gotten to the attitude of “Quit asking government permission to live life.” Defiance to anything they demand is my new norm…and staying under the radar as much as feasible.

  6. I’d be curious to know how the Brits (courts/judges?) handle the matzeivah erected on Jewish graves, many of which are engraved in Hebrew.

    • Probably not an issue since it’s not an objection to non-English per se. The judge qualified his “concerns” that an Irish Gaelic phrase would be seen as a political (rebel) statement. Hebrew could not be interpreted as political unless the person who put it up explicitly declared that it was meant to be political. In the same way, a headstone in Norwegian or Portuguese would not be seen as politically subversive.

      I picked Arabic and Mandarin because those could easily be laden with political meaning in the context of the West, but maybe those were suboptimal examples. Maybe I should have said Basque language in Spain or Tibetan in the PRC.

      • not to belabor the point, but… (heh!)
        “Untranslated Irish(Hebrew) words(letters) would be ‘unintelligible to all but a small minority of readers’, he ruled in his judgment”
        and these days with a strong minority? of Muslims in Britain (and Ireland), anything Jewish/Hebrew can very easily be taken as highly offensive (and probably political).

    • Well, England has always been anti-Jew since the 1200’s, so…

      Seriously, Germany got the bad press for it, but both France and England have been very Jew-Unfriendly for centuries.

  7. Thanks for the nod. I’ve been getting a lot of that lately. No need to worry there’s no way we’re one in the same as I firmly believe owning a lot of stuff and being happy…
