Again where do you get this? How is this sentence remotely logical? sources?

Novae is a result of a star under immense electrical stress... it is an exploding double layer.

How could this possibly be in a resonant electrical state? (relaxation oscillator). It's nothing like one?

So so far off the page...

"When I was researching topics for this article, Wal Thornhill said to me,

"Have a look at variable stars, particularly bursters, where I think you will find the brightness curve is like that of lightning with a sudden rise time and exponential decay. Some stars are regular and others irregular. The irregular ones seem to average the power over the bursts. When they are more frequent, the energy is less per burst. If there is a long latency, the next burst is more powerful. It's the kind of thing you would expect from an electrical circuit when the trigger level is variable and the power input constant.
I think many variable stars are actually binaries with some kind of electrical interaction. Long period Miras (A type of variable star) may actually have an object orbiting within the shell of a red giant (as I have proposed for the proto-Saturnian system)"

Following Wal's suggestion, I looked at the recent Hubble image of Mira itself, the flagship star of that class of variable stars. Mira's image reveals a huge plasma emission on one side of the star. The official explanation includes the words, " Mira A is a red giant star undergoing dramatic pulsations, causing it to become more than 100 times brighter over the course of a year. …. Mira can extend to over 700 times the size of our Sun, and is only 400 light-years away. The …. photograph taken by the Hubble Space Telescope shows the true face of Mira. But what are we seeing? The unusual extended feature off the lower left of the star remains somewhat mysterious. Possible explanations include gravitational perturbation and/or heating from Mira's white dwarf star companion." [Italics added.]


Mira has a white dwarf companion, just as Wal suggested was likely. So, a much better possible explanation of its pulsating output is that an electrical discharge is taking place between Mira and its companion, much like a relaxation oscillator. It's not really "mysterious" at all. There are many examples of unequally sized, closely spaced, binary pairs that are variable and emit frequent nova-like explosions. The list includes:

• • SS Cygni - A yellow dwarf and a hot blue-white dwarf. Orbital period 6.5 hours! Separation distance 100.000 miles or less. Burnham asks, "Is SS Cygni ..... dying out after having been [a full scale nova] in the past?"
  • U Geminorum - A B-type blue dwarf and a G-type dwarf. Orbital period 4.5 hours! Separation distance a few hundred thousand miles. In this case Burnham states, "Spectroscopic studies reveal the existence of a "rotating ring of gas" (plasma) around the blue star, and it appears that the explosive increase of light is due not only to the brightening of the star, but to a large increase of radiation from the cloud."
  • Z Andromedae and R Aquarii - Both of these consist of a hot blue dwarf mated to a red giant.
  • T Coronae and RS Ophiuchi - Both have recurrent nova-like eruptions and are close binary systems"
