What electric field centred on the nucleus? What on Earth are you on about? The surface can charge up when the comet is at low activity. That is, before the DC forms. Once it forms, the solar wind has no access to the nucleus. So it becomes irrelevant.

You are serious?

You know the papers confirming the electric comet!

like me to dig them out?

Quote:
Fig. 7. Upper left: Observed cometary ion bulk velocities in CSE. Lower left: Observed solar wind proton bulk velocities in CSE, with their
theoretical trajectories. Upper right: Indirectly observed motional electric field. Lower right: Schematics of the three terms of the total electric field
(interpretation).

67P/Churyumov–Gerasimenko


Where is the E ambipolar centred?

and in case you are a bit slow this is the cause of your "diamagnetic cavity"!
Quote:
The third term, the ambipolar electric field Eambipolar , is expected
to be significant close to the nucleus. At zero order, this
electric field points radially outward from the nucleus. It might
be one of the reasons why close to the nucleus the modelled
proton trajectories in Figure 7 depart from the observed velocity
vectors. Another effect arising from the ambipolar term is
a polarisation electric field due to the different motion of the
cometary new-born electrons and ions.
whoo boyo!

Complete and utter piffle. No, it is not the cause of the diamagnetic cavity, and nobody is stupid enough to think it is. Nor has such a thing been written anywhere. Only one person on the planet thinks that, and he hasn't got the foggiest what he's on about. The diamagnetic cavity has disappeared at the time of the tail excursion!

If only there were an actual electric comet model, then we could check the observations to the model.
However, what we now have is that any mention of something electric is a confirmation of the non-existent electric comet model.
The EC community is not even trying.

10 September 2018: A deluded lie that E. Behar et.al. states the cause of the real diamagnetic cavity to be his electric comet insanity.
Invalid link fixed: The root of a comet tail - Rosetta ion observations at comet 67P/Churyumov--Gerasimenko by E. Behar et.al.
Quote:
However, as observed 30 km away from the nucleus, these expanding ions are not moving purely radially, and have an additional anti-sunward component. As presented by the same authors, the acceleration of this population could in part result from a radial ambipolar electric field, set up by charge separation between fast moving electrons and slower ions, due to pressure gradients of the spherically outflowing atmosphere.
Part of the delusion is putting the real, observed diamagnetic cavity in quotes.

A delusion that a ambipolar electric field is the cause of the diamagnetic cavity. The cause is the interaction of the solar wind with the cometary coma ions. I suspect that would actually contribute to the existing ambipolar electric field.
Structure and evolution of the diamagnetic cavity at comet 67P/Churyumov–Gerasimenko

Another part or the delusion is blatant lying about the ambipolar electric field (matching the paper description). This is an electric field within the plasma of the coma caused by charge separation of lighter electrons and heavier ions plus the obvious pressure gradient from the outgassing of sublimating ices.

An ambipolar electric field is not an insanely repeated delusion of an electric field from the comet nucleus .

Ummmmm.....every new paper CONFIRMS that electric fields and related plasma processes are the dominate factors at play here.

The paper CONFIRMING the ELECTRIC COMET model will be whoever puts the paper out modeling

Quote:
The extent of the region in which the ambipolar electric eld may dominate has not been investigated yet, and does not appear as a sharp boundary in the present results. Far from trivial, this topic would most likely require the use of self-consistent fully kinetic numerical models.
Quote:
Numerical models would be appropriate for investigating further this source of electric field, as was done for example by Huang et al. (2018)

The third term, the ambipolar electric field Eambipolar , is expected to be signicant close to the nucleus.

For more detailed studies a proper simulation model is still needed, and our results indicate that important physics will be missed unless electrons and charge accumulation are taken properly into account.

Results. Observations of the local plasma density and magnetic eld strength show that the parameter range of the observations agree very well with a signicant polarisation electric eld shielding the inner part of the coma from the solar wind electric eld. The same process gives rise to a tailward directed electric eld with a strength of the order of 10% of the solar wind electric eld.

And you believed neutral gas was holding the solar wind back...

Again electric comet model confirmed.

It’s only your stubborn belief in the infallibility of RSI experiment is giving you a bum steer on the bulk density guess.

First: there is no electric comet model (unless you can point me to a paper describing the how and what of an EC).
Secondly: you cannot read, your quote says that "a signicant polarisation electric field shielding the inner part of the coma from the solar wind electric field"
It is nowhere stated that the polarization electric field is creating the diamagnetic cavity.

Nope. The fact that the spacecraft didn't crash while in bound orbits is a clue. If you think otherwise, show us the charge needed to keep it in those orbits, as if they were orbiting an object with the measured density of ~ 500 kg.m^3. Can't do it can you? Which is why you are off on another bout of failing to understand papers that have nothing to do with the electric comet impossibility.
Yawn.

What it is going to be is that you still don't understand what you are quoting (no surprise there). What does the electric comet do? Apparently it is constantly discharging and with that machining the surface of the comet. But to do that you need incredibly strong electric fields, whereas the electric fields that are talked about in all the RPC data are on the order of the thermal energy of the ions with probably the strongest being the solar wind electric field at millivolts per meter.
At a non-active comet, Nordheim et al. estimate that the electric field can become up to +/- 2 V/m (for day/night side) because of surface charging.
This is all not quite the stuff that discharges make.
But then again, you could present an actual electric comet model in which we can read what we should expect in the measurements.

So, now you understand (no probably not) why we say "nothing electric" is happening, as the claims by the EC community are "out of this world" (which then again would be good for space physics). Plasma physicists are well aware of electric fields, but they are also aware of the limitations to the electric fields (or the magnetic fields for what it's worth). So, not every mention of an electric field is a confirmation of the non-existent electric comet model.

How is it possible to confirm a model that does not exist? You have been asked over and over on these pages to lay out the ELECTRIC COMET model, but you have declined to do so, or have quoted just about any paper about comet with the word "electric" in it as "confirming" the theory.

Guys, I am sorry to inform you that you are all wrong, it has now been confirmed 100% sure that the Electric Comet does exist...
