Ionized

In visible light nebulae may be divided into emission nebulae that emit spectral line radiation from excited or ionized gas (mostly ionized hydrogen ); citation they are often called HII regions (the term "HII" refers to ionized hydrogen).

Even a partially ionized gas in which as little as 1% of the particles are ionized can have the characteristics of a plasma (i.

Lyman J Spitzer, "The Physics of Fully Ionized Gases" 1963 Spitzer took the ideal gas laws and adopted them to an ionized plasma, developing many of the fundamental equations used to model a plasma.

Neutral metals ( Fe I, Cr I) beginning to gain on ionized metal lines by late F. Their spectra are characterized by the weaker hydrogen lines and ionized metals.

The parathyroid chief cells secrete parathyroid hormone (PTH) in response to a fall in the plasma ionized calcium level; the parafollicular cells of the thyroid gland secrete calcitonin in response to a rise in the plasma ionized calcium level.

The shell can be clearly seen in optical emission from recombining ionized hydrogen and ionized oxygen atoms.

As the nebula throws off its outer layers of ionized gas, it reveals its characteristic blue interior, composed of hydrogen and oxygen that have not yet been expelled off by the nebula’s stellar wind.

Fast radio bursts have a unique ability to detect this ionized matter.

Look closely, and you'll spot that comets have two tails, one made of ionized gas and another of dust.

ICM, consisting mainly of ionized hydrogen and helium, is held together by the gravitational pull of the cluster itself.

When these ionized particles impact Europa, they break up the water-ice molecule by molecule on the surface to produce hydrogen and oxygen.

Like all planetary plasmoids, it was full of charged particles—mostly ionized hydrogen, the authors believe.

X-rays capture the ultrafast proton transfer reaction in ionized liquid water, forming the hydroxyl radical (OH) and the hydronium (H3O+) ion.

In fact, it’s enough to break apart its (and the atmosphere’s) constituent molecules into ionized particles (basically plasma), which then recombine, releasing energy as light.

Ionized air in the resulting smoke and combustion particles may turn into an electricity conductor that would cause arcing on the overhead line.

The fuzziness of the pin is because the camera did not actually capture light reflected on the pin but rather the light emitted by the ionized light around it.

A special type of radiation appears: emission lines, as electrons fall back onto the ionized atomic nuclei.

At the core of these active galaxies, supermassive black holes launch high-speed jets of plasma – a hot, ionized gas – that shoot millions of light years into space.

Aerodynamic heating surrounds it with an envelope of ionized air which causes a communications blackout for several minutes.

A few completely ionized nuclei of heavier elements are present.
