Is it possible that a neutron star might have hydrogen gas
in orbit around it?

Probably not in orbit, unless there is a nearby star giving it some
matter in the form of a solar wind. There may be some on the surface,
but not a lot.

Does a neutron star have enough force of gravity to
cause hydrogen atoms to fuse into helium atoms,and create a fusion bomb?

It has the gravity, but such fusion would require a lot of it falling
onto the neutron star. In any event, infalling matter might drive the
neutron star over the Chandrasekar limit and form a black hole.

Isn't just that sort of thermonuclear explosion supposed to be the cause
of type 1 supernovae? How do we know that the object at the centre is a
neutron star and not a white dwarf as usually thought?
And there has been a report of a fusion explosion on a neutron star,
though it was carbon and not hydrogen that was involved

http://www.gsfc.nasa.gov/GSFC/SpaceSci/structure/rxte3hrnuke.htm

(further checking finds that it's carbon in type 1s, too, and they don't
have hydrogen lines in their spectra, But you're close, Bert !)

Well close is good in megaton bombs. I wonder what created Jupiter's
great red eye. Are there any theories on it? Was it caused by two
opposing gases(like jet streams) Earth's jet stream gives energy to
tornadoes. Could a very large meteorite hitting and compressing the very
dense atmosphere causing a vortex (whirl-pool)? Could this be a result
of Jupiter's very fast spin? Bert

Bert, ya done asked before about the Great Red Spot, but didn't seem to
read the answers.g Maybe try again. I read this theory many years ago
which goes like this (paraphrasing)-

In fluid dynamics, when a linear flow passes a critical velocity, it
must break into a vortex, as seen in a tornado, waterspout, bathtub
drain and the like. On Jupiter, the speed differentials between the
laterally-moving bands of the atmosphere have passed the critical
velocity, with the resultant formation of the Great Red Spot vortex. Its
permanence is the result of the permanence of those wind-speed
differentials. In other words, if the winds would slow down and the
speed differentials decreased sufficiently, the GRS would shrink and
vanish. =A0 =A0oc

Hi oc I've asked the same question,and I'm in hopes that I get a
different answer,and is closer to reality. That eye is the biggest storm
in the solar system. Could be the biggest planetary storm in the
universe?. It shows that one side of Jupiter's atmosphere is more
turbulent. Its area is many times bigger than the Earth. I know it is a
mystery,and would like to hear theories,and get more information on it.
Like does it drift? How much does it drift?. In time is it going to be
on the other side of Jupiter? Does the solid surface of Jupiter turn
under it? Bert

Yup. that's why there's are two GRSs, one in the northern hemisphere and one
in the south.

It may be that the wind differentials vary, sometimes above and sometimes
below the gradient threshold needed to provoke a GRS into being. Once a GRS
exists, maybe it has in inertia that lets it persist for a little while if
the gradient falls below the threshold. We've been observing the GRS for
only a few hundred years, which is a small time compared to the age of
Jupiter. Maybe sometimes there is a GRS in the other hemisphere too, but we
haven't seen it yet.

I seem to remember that there are storm "spots" in the atmospheres of Saturn
and maybe Uranus and Neptune too. But I haven't been following the
literature closely on the subject.
