When white dwarf meets brown dwarf, pow!

In the 1600s, western astronomers were just emerging from centuries of medieval thought, when the heavens were thought to be unchanging. You can imagine their astonishment when – in July of 1670, in what had been a blank, dark sky – some observers witnessed a bright pinprick of light that appeared, faded, reappeared, and then disappeared entirely from view. At that time, astronomers called such an event a nova or new star. This one was located in front of the constellation Cygnus the Swan and so received the name Nova sub Capite Cygni (a New Star below the Head of the Swan). Modern astronomers have learned it wasn't a new star. It wasn't even a spectacular collision of two main-sequence stars, as announced in 2015. Instead, using data from the ALMA telescope in Chile, astronomers now believe the event was a collision between an aging white dwarf star and a brown dwarf (star with too little mass to ignite thermonuclear fusion and thereby shine as most stars do).

The object in question is now called CK Vulpeculae.

The new work is based on observations with the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile. The astronomers studied the debris from this explosion, which takes the form of dual rings of dust and gas resembling an hourglass with a compact central object (see image at top). Sumner Starrfield of Arizona State University is a co-author on a paper published in the peer-reviewed journal Monthly Notices of the Royal Astronomical Society. He said in a statement:

It now seems what was observed centuries ago was not what we would today describe as a classic 'nova.' Instead, it was the merger of two stellar objects, a white dwarf and a brown dwarf. When these two objects collided, they spilled out a cocktail of molecules and unusual isotopes, which gave us new insights into the nature of this object.

Brown and white dwarf stars.

                i'll defer the etymology to your vast erudition, magister.
                I'm only mocking a language that's not my own and it will never be, so what do I have to lose?
                So here, raise a glass of retsina in the honour of the terrible wrong Novæmber - I just sacrificed a word in two languages on the altar of Seth or whatever god of chaos you want

                Different words in Latin, which since it is the pater language of Romanian, um, you should have known?

                Maybe I should, maybe I shouldn't, how the heck would I know? I feel not bound to be correct or relevant.
                Not only it become tiresome after a while, but one also loses the ideation generative juices of being wrong on purpose and see what other angles this can reveal. The trick is to be conscious you are likely to be wrong and not linger in one kind of wrong for long.

                Remember, magister, the risk of answers - especially the right ones - they have big potential to kill. How many people can answer to "What do you want to eat next" after they just had a heavy meal?

                Besides, what makes you so sure "unadulterated reality" and "be true all the time" is what the humanity needs?
                "And ignorance is, first of all, this false identification of Reality with what each one of us appears to be or to possess." Think if the proposal of the hierophany as necessary for humans may not be actually valid, as "wrong" as it may be. Maybe the feeling of the mythological sacred is necessary for the human species?

        And the semantics and spelling in different languages is relevant exactly how?

        Not saying that the Buzz'es post makes a relevant or on-topic comment, but... really... do we need to continue a lame pun with irrelevant etymological considerations when we could have instead a nice aristarchus' story to comment on?

        (grin)


        For example, this one [soylentnews.org], which became quite relevant after Australian senators for the party in power backed a "It's OK to be white" motion [abc.net.au].

        The motion, moved by One Nation leader Pauline Hanson on Monday, was narrowly defeated 28 votes to 31, despite the Coalition's backing.

        It called on the Senate to acknowledge the "deplorable rise of anti-white racism and attacks on Western civilisation" and that "it is OK to be white" — a phrase commonly used by white supremacists.

        Facing an almost immediate backlash, Attorney-General Christian Porter, whose office directed Coalition senators to vote in favour of the motion, defended the move on social media.
        ...
        But on Tuesday morning a clearly unimpressed Mr Morrison [the prime-minister] described his senators' support for the motion as "regrettable", prompting Senator Cormann to apologise a short time later.

        "We should have opposed the motion when it came up in the Senate yesterday [Monday]," he said.

        "As the Leader of the Government in the Senate, I take responsibility for that error and I'm sorry that it happened.

        "It is indeed regrettable."

        How the hell the 4chan trolls managed to create such a waste of time globally?
        More importantly, did we, as a society, intellectually regress so much that 4chan can do worse? Or we were always this stupid and we are now just learning to live with out stupidity?

          I must say, there is nothing like an Australian after they have become angry at Nazis and their allies. The attack on Darwin is a case in point. And to see your own government go so entirely alt-right? That is something that only American and Kiwis could sympathize with. But back to the point. Ignorance like TMB's, whether in fact or in pun, is what is destroying civilization. Intentional ignorance, like khallow saying he is not sure that Anthropogenic Global Warming is real, is also delsutory. Or that of TMB, only able to relate science to models of automobiles (so American, that! At least he could have chose a Plymouth Satellite!). But in either case, the dumbing down of the English speaking world, as if the Bruces were not bad enough already.

          So, c0lo, master that you are, is there any hope for the land down under? Jim Jefferies, and Lucy Lawless (not to mention Mel Gibson, whom I will not mention) have all gone states-side. But the alt-right seems to have the "Shrimp on the Barbie" nation in its sights. Does Australia have the resources to withstand the Brexit Anschluss?

          And, yes, it would be nice to have an aristarchus submission to comment on, perhaps something about dictionaries, very non-inflammatory and edifying, but it seems that the #Freearistarchus!!! movement needs a bit more of a push? I recommend mocking and ridiculing the editors, calling out their bubble and Americo-centric bias, even though that will just drive them closer to janrinock and his pro-Brexit cronies. SoylentNews is doomed. But then, I have said this many times. And khallow is still here.

            Context, magister, context. Learning needs one, and S/N is not a good one for TMB.
            In his mind, he controls this space. An authoritarian never learns from the subjects under his authority, learning from the master is what's expected from them subjects.
            Do you get it yet, subject aristarchus?

            If that amuses you, by all means. Otherwise, see above.

            But in either case, the dumbing down of the English speaking world, as if the Bruces were not bad enough already.

            You give the TMBians too much credit They are bruces themselves and love the bliss of simple-mindness.
            They may even become aggressive if you try to shake them out from this state.

            is there any hope for the land down under?

            Maybe there is - most of the people around me mocked the stupidity of those trolled.
            But then again, what the hell do I know about others?
            Maybe there is [bbc.com], maybe there isn't [wikipedia.org] (I used an oldish event to show the undercurrents aren't a recent acquisition)

            Does Australia have the resources to withstand the Brexit Anschluss?

            Fortunately, things like droughts and catastrophic floods and bush fires inject some doses of reality in the public mindset.

            Trying to change the mindset of authoritarians who feel they have something to demonstrate is a waste of time. They know they are right, this is a settled matter for them. Too bad if it is not so for you and me or anyone else, not their problem.

              "Subject aristarchus"? Surely you know that #Freearistarchus!!! is snark. I am free, and have always been, being a Greek and a scholar and whatnot. But I can recommend my strategy for escaping the authoritarians, of whom we have had our lot in Greece, from Polycrates on Samos, to Pisistradus in Athens, and Alexander over us all, and many domestic and foreign rulers throughout time: don't die! I have escaped many tyrants by outliving them. But more importantly, I have freed my mind, so that the longevity strategy was not really even necessary.

    Does anyone else find the terms "dwarf" and "brown" offensive? It's 2018 and we can do better. What about miniature star? And did it fail to light up because it is brown? Only bright white is successful? That's downright offensive.

        Still waiting for one about the white one killing the brown one for reasons. I'd offer one up but can't think of one. I'll just wait until Fark gets ahold of this news.
