Live and Let Die(1973) is the eighth spy film in the James Bond series, and the first to star Roger Moore as the fictional 007 agent James Bond. Euthanasia refers to the practice of ending a life in a painless manner, to live and let die. Euthanasia provides a way to relieve extreme pain, provides a way of relief when quality of life is low, frees up huge resources from diminishing returns, and is manifestation of selfownership. Even stars commit euthanasia in the form of supernova explosions! http://venitism.blogspot.com
Hagai Perets of Harvard discovered a new euthanasia of stars! These stellar euthanasias are different from known supernovas in several ways. Like ordinary supernovas, they can briefly become the brightest objects in the sky, but they are more short-lived, waxing and waning in a matter of days rather than weeks, as with more typical supernova. They also eject far less material in their explosions and don't seem to be powered by known processes.
"It's a very good puzzle," Perets says. "This is very strange."
Supernovas are among the most spectacular events in the universe, marking one way that stars end their lives, a form of euthanasia for stars! They can briefly become so bright that they outshine their entire home galaxies. They're important for another reason as well. Because stars are fueled by nuclear fusion, in which smaller, lighter elements fuse to form heavier elements, they become factories in which heavier elements such as carbon, oxygen, and iron are created. The explosions that destroy stars create even heavier elements and scatter them over large distances to places, including Earth, where they eventually can be used by living things.
Perets points out these new supernovas may result from the explosion of a kind of star called a white dwarf and that such a euthanasia blast may involve only the star's upper layers. Because white dwarf stars are smaller and less dense than larger ones, these new euthanasia explosions may prove to be a source for intermediate elements.
"Maybe it produces a large fraction of the calcium in the universe," Perets notes. "Probably other intermediate elements are produced in higher quantities."
Researchers at the California Institute of Technology have already uncovered another example of this type of star euthanasia, called SN 2010X. Perets notes more star euthanasias may be found now that astronomers know how to look for them, producing additional information that may help solve the mystery of star euthanasia.
"We're going to know more about these in the next few years," Perets saYS. "It's going to be a puzzle for theoreticians."
