Could a red dwarf be "deionized"?
Even the smallest red dwarf stars have amazing flares. But the photosphere temperature can be as low as 2700K, which (I think) is too cool to ionize hydrogen. Even the sun at 5800K is cool enough that ...

What is value of charge by mass ratio (q/m) for a spherical micro charged particle with surface potential 6 volts in S.I units and in e/amu units?
In Liu and Ip (2014),The Astrophysical Journal, 786:34 (8pp), the value of q/m is derived as follows :
"for a dust grain with radius 'a', from $\phi = \frac{4\pi q}{\varepsilon_0 a}$ we have $\...

Would impacting plasma clouds destroy electronics on Earth or make them only temporarily inactive?
We read that solar flares have increased again recently. At the same time, it is always reported that the plasma clouds hitting the Earth would, under certain conditions, disable all electronics on ...

How to build functional sunspot model on the ground with high-power plasma burners in the strong magnetic field as conference paper?
I need to build functional sunspot model on the ground with high-power plasma burners in the strong magnetic field as conference paper.
What I get is light-weight plasma, as exactly plasma is.
But I ...

Is the Solar core hard?
This may seem like a weird question, but something got me thinking about it just recently.
The Sun's core is composed of mainly hydrogen and helium, and is present in the form of a extremely hot ...

Question about plasma parameter
As we know, the deflection angle in strongly ionized plasma can be written as $$ \tan \frac{\theta}{2} = \frac{l_0}{l}, $$
where $\theta$ is the deflection angle, $l_0$ is the impact parameter when $\...

Do the newly-created deuterons in our Sun release any photons? In addition to a positron and an electron neutrino?
Perhaps this is a nuclear physics question, but....
When two colliding protons deep inside our Sun finally turn into a deuterium nucleus or deutron (after approximately ten octillion chances, on ...

How is the H II 'region' directly detectable? By Compton or Thomson free-particle scattering? At what wavelengths?
The Wikipedia page on H II regions says that they are 'indirectly' detectable by the detection of doubly-ionized oxygen atoms mixed in.... (I am presuming atoms, not diatomic molecules...)
But are ...

Are plasma nuclei detectable? By the occasional emission of gamma rays, perhaps?
As stated above....
How often do nuclei stripped bare emit radiation?
Can nuclei be identified by the wavelengths or amplitudes of gamma rays they emit? How about isotopes?

Is it possible to observe Lyman-continuum emission from extragalactic objects?
Lyman-continuum (LyC) emission is everything blueward of 912 Angstroms (so it includes extreme UV photons, X-rays and gamma rays). There are many low-redshift astrophysical plasmas such as the diffuse ...
