Running away Henry? Show me the maths that led to
your conclusion.

The obvious fact is that they would be traveling at maybe
c/2 towards Earth if they did. They would be extremely
redshifted. Maybe they are! Maybe they start out as UV
moving at c/2 wrt us.

You seem to think that quantities are important in science.
You suggest that the speed of light leaving a neutron star
might be c/2, a specific quantity.

Another quantity is implicit in your paragraph above.

You know that the signal received from J1909-3744 is in the
radio UHF band, at 1.3 GHz, or a wavelength of 230 mm.
You must know that UV has a wavelength of around 100 nm.
And you must know that if the speed of the wave was divided
by two, the wavelength would be multiplied by two:

100 nm * 2 = 200 nm

But the result you want on the right side of that little
equation is 230 mm. Your guess that the light would need
to be emitted as UV in order to be received as radio was
off by a factor of over a million. The correct value for
the initial wavelength is 115 mm.

How could you possibly be so enormously far off on such an
elementary calculation? Is it because you have no intuitive
sense of scale? That is what it looks like. You know that
a wavelength of UV is shorter than a wavelength of radio,
but to you that means it is maybe half as long. No wonder
you can't understand how things work.
