Star Within a Star: Thorne-Zytkow Object Discovered

astroengine writes: "A weird type of 'hybrid' star has been discovered nearly 40 years since it was first theorized — but until now has been curiously difficult to find. In 1975, renowned astrophysicists Kip Thorne, of the California Institute of Technology (Caltech) in Pasadena, Calif., and Anna Zytkow, of the University of Cambridge, UK, assembled a theory on how a large dying star could swallow its neutron star binary partner, thus becoming a very rare type of stellar hybrid, nicknamed a Thorne-Zytkow object (or TZO). The neutron star — a dense husk of degenerate matter that was once a massive star long since gone supernova — would spiral into the red supergiant's core, interrupting normal fusion processes. According to the Thorne-Zytkow theory, after the two objects have merged, an excess of the elements rubidium, lithium and molybdenum will be generated by the hybrid. So astronomers have been on the lookout for stars in our galaxy, which is thought to contain only a few dozen of these objects at any one time, with this specific chemical signature in their atmospheres. Now, according to Emily Levesque of the University of Colorado Boulder and her team, a bona fide TZO has been discovered and their findings have been accepted for publication in the Monthly Notices of the Royal Astronomical Society Letters."

      Hate to turn something funny into a serious note, but I'm pretty sure a lot (if not most) of the comments on the internet can already be predicted just by looking at the headline.

      I suggest calculating an originality score for all comments based on their similarity to all previous comments. If it could be based on all the comments you've personally encountered before, it would drastically cut down on the 'Oh god, not this bullshit again'-feeling we all have when perusing comment sections.

      On the other hand, sometimes you predict that a certain comment will have been made and feel satisfaction upon reading it.
      Maybe that's a bad thing, too.

    I used to think adblock was unnecessary back when google was doing the whole "unobtrusive text ad" thing, and I saw a future with hope for ads being reasonable things. But it's been years since that was worth worrying about.

    Marketers haven't learned that their obnoxiousness is a tragedy of the commons thing, and upping that factor to compete just quietly hurts the marketplace as a whole.

      Isn't actually making the meme-image pretty superfluous in this case?

      Unfortunately, given that the original "Yo Dawg" was marked as "offtopic" by twice as many people as thought it was funny, it probably *is* necessary.

      Shame, as the minimalism of the original poster's joke worked- for me- because it assumed that most of us were familiar with a long-established meme to be able to dispense with the full text (i.e. playing off its clichedness rather than it being a boring rehash of a now-tired cliche) and also that we were smart enough to figure out its relevance to the headline story.

      Not sure if the moderators didn't get the reference, or just couldn't figure out how it applied. This is why we can't have nice, minimalist jokes on Slashdot without it being necessary for someone else to overegg the pudding and explain them. :-(

    The star in question is a ball gravitationally bound of gas that has a reasonably well defined perimeter, with a neutron star (a ball of also gravitationally bound degenerate matter) orbiting it at some distance.

    The neutron star which was orbiting the other star, is now (due to the first star expanding as it transitions to the red giant stage) within the perimeter of the first star.

    So in other words: the same damn definition of "inside" you use for things in every day life, what's to not understand?

    It's not a good idea to use words one doesn't understand just because they might sound cool. A husk is a left over outer shell or covering. A neutron star derives from the inner layers and core of the original star--the summary writers could hardly have chosen a more ill-fitting word. That the degenerate matter in a neutron star is a superfluid, juxtaposed with the more specific meaning of husk as the _dried_ outer portion of a fruit or nut, takes this misuse of the word into the realm of the ludicrous.
