http://www.astronomy.com/news/2017/05/white-dwarfs-may-create-antimatter More than four decades ago, astronomers discovered the first gamma-ray emission coming from outside the solar system. This high-energy signal is associated with the destruction of roughly 1043 positrons — a type of antimatter — each second. Despite extensive follow-up, astronomers today are still looking for the exact source (or sources) of this emission, which could run the gamut from mundane (natural processes in a star’s life) to exotic (dark matter) origins. Recently, a group of astronomers has determined that positrons resulting from white dwarf mergers could contribute significantly to the signal we see. The emission associated with galactic positron annihilation occurs when a positron meets its counterpart, an electron, destroying both particles in the process. Thus, this emission requires a ready source of antimatter, which has remained mysterious ever since its initial detection. Measurements suggest that the signal is nearly one and a half times higher in the bulge, or central regions of the Milky Way, than in the arms. This particular aspect of the emission has led to the development of several models that speculate an overabundance of positrons in this area could be due to processes related to dark matter or our galaxy’s central supermassive black hole. However, many astronomers are still searching for less exotic ways the positrons we’re seeing undergo annihilation could be produced. In a paper published May 22 in Nature Astronomy, first author Roland M. Crocker of the Research School of Astronomy and Astrophysics at Australian National University and his co-authors examine a possible stellar source of galactic positrons that could be responsible for the signal: white dwarf mergers. White dwarfs are the remnant cores of Sun-like stars, left behind after the star runs out of fuel and dies. If two low-mass stars (between about 1.4 and 2 times the mass of our Sun) circle each other closely in a binary system, they can interact via a process called mass transfer, where gas from the stars is exchanged. The end result is two white dwarfs that may eventually merge, and that merger can result in the production of radioactive isotopes that decay into positrons. There are several clues that have led Crocker and his co-authors to this conclusion. The ratio of the signal’s strength in the bulge and arms is similar to the ratio of the stellar mass (essentially the number of stars) in these two structures as well. This led the astronomers to consider that the positron production could be related to an older stellar population, such as white dwarfs. Additionally, by looking at the processes that produce positrons through radioactive decay, they determined that the decay of 44Ti into positrons is the most likely source. However, this material is not produced in sufficient amounts in most core collapse supernovae, which occur when a massive star reaches the end of its life. While supernovae triggered by the merger of two white dwarfs are much rarer, these events should produce more 44Ti per merger, which would then decay and produce the number of positrons required to create the emission line from their subsequent annihilation. The current resolution of instruments used to study this emission is not high enough to find point sources, such as individual supernova remnants, in the bulge. Thus, more precise measurements and computer simulations will be needed to determine the positron production rates from such events. The authors also state that white dwarf mergers are likely not the only source of antimatter in our galaxy, which still includes contributions from massive stars and black holes, even if dark matter is eventually ruled out as a viable source for this emission.

No. Opposite star arms share the same spin making them opposite matter (antimatter). There are thus exactly the same amount of each, just as there should be.

Of course, when I suggested that galaxies are half antimatter, Odd asked where all the signs of positron/electron annihilation are- there should be some if opposite arms are beside each other: Obvious that he didn't know about this: "More than four decades ago, astronomers discovered the first gamma-ray emission coming from outside the solar system. This high-energy signal is associated with the destruction of roughly 1043 positrons — a type of antimatter — each second.

It has been observed that galaxies' arms are at the axis of a helical magnetic field. That axis must have a spin direction. The arm exactly opposite must have the same axial spin. Since it is facing exactly the opposite way, all of its matter will have exactly the opposite spin. Antimatter makes up exactly half of galaxies, or tries to. The analogy with atoms is the 'spin up' and 'spin down' electrons, which being exactly opposite each other share the same orbital.

'Snicker' White dwarfs are antimatter??? That's what lack of a model does to Science. No bearings. It's like they're in a white-out snow storm, or firing at noises in the dark.

MM My model for the Atom is the spiral galaxy. It's called "The Galaxy Model for the Atom". Opposite star arms correlate with up/down electron pairs. The helical field surrounding the primary star-arm- correlating as it does with the up electron- means that the opposite star arm will have the opposite helical field. One field has Matter stars. The other field has antimatter stars. These ideas come because I HAVE a model. Perhaps they're right about white dwarfs; perhaps they drift to the edges of the arms in both cases, and interact. Track some.

A scientific model has rules or formulas that state things like "if you do this, that happens" with rather specific statements, not just handwaving. Such as "if you drop an object on Earth, the position of the object as it falls can be described by: y(t) = -(g*t^2)/2. In other words, given a time, you have an exact position prediction. That's a model for gravity on the earth's surface. All you have is handwaving with absolutely no support, and usually conflicting with already made observations. >Opposite star arms correlate with up/down >electron pairs. Vacuous, with no evidence. >The helical field surrounding the primary >star-arm- correlating as it does with the up >electron- means that the opposite star arm >will have the opposite helical field.

No, John, that's not a prediction as how science uses it, since you think everything is retarded spinny things, with no explanation why, other than OCD or something. No evidence supporting your "prediction", only vacuous claims. The best we can say about your "prediction" is that a stopped clock is correct twice a day. A real prediction has a model which takes some parameters that produces some result (a prediction). Such as the simple gravity model I mentioned earlier. You can plug in the height of the Empire State Building into it and predict exactly how long it would take for a rock dropped from the top of Empire State Building to reach the ground. That is a real prediction.

MM ".. top of Empire State Building to reach the ground. That is a real prediction. " So, forseeing a magnetic pole at rightangles to the galactic disc, and that it is spinning, and that atoms are instantaneously disclike are not predictive?

MM "Why yes, since the Standard Model predicted that and we saw that, that is another piece of support for the standard model! I'm glad you approve! " Well, in the mid-80s when the VLA saw that, the article said it was a complete surprise to see the magnetic field like that.. I could show you the article. I'll bet you can't show me where and/or why Standard Model predicted that, pre-1986.

Haha. I like how they say 'may create most' of our antimatter. That leaves it completely open for there to not only be other sources (VERY open-minded), but for the white dwarfs to maybe NOT even contribute the most!!! Very forward-thinking. Who is paying these deep thinkers?

Who is paying these >deep thinkers? That's how science works, John. We make observations, we see something puzzling, we have questions, we come up with a hypothesis that is a possible answer to the questions, we make more observations to try to refute/validate the hypothesis, and in the process, we may answer some questions but more puzzling observations may bring up more questions. This is not a fault in science, in fact it is a strength. Remember, the goal of science is to figure out how nature works, so any changes to the model we have that is closer to the truth is a plus, not a minus.

They only know that it's coming from beyond our solar system, presumably from within our galaxy. There was no mention of other galaxies.
