So do they mean matter in the 3rd or 4th state?

Would you please spend a few minutes to learn how to make a URL link in an article?

At these kind of temperatures and near these kind of objects they mean that the gas is a plasma.

A plasma is a gas in which a significant amount of the constituents is ionized, i.e. the atoms have lost one or more electrons. The ionization degree must be high enough to make collective processes possible (usually the number of electrons in the deBye sphere must be much larger than 1). Then we talk about a plasma, also called "the 4th state of matter", however, it still remains a gas. A bit confusing maybe, but if you follow this reasoning, you might understand.

Well thanks for the instruction ;-) I learned something new today again ;-)

The reason it didn't come out as a proper link is that he mis-typed
or mis-copied or accidentally deleted the beginning of the URL, so
the forum software didn't recognize that it was a URL.
