Abstract

The stability of a dilute gas in mechanical and thermal equilibrium is studied with a view to applications to non-gravitational condensation phenomena in astronomy. It is shown that, under a wide range of conditions, thermal equilibrium is unstable and can result in the formation of condensations of higher density and lower temperature than are found in the surrounding medium The instability criterion is shown to differ considerably from certain criteria proposed by previous authors. The modifications due to finite speed of sound, to thermal conduction, to a magnetic field, to rotation, to an external gravitational field, and to expansion of the medium are studied. Applications are made to the solar chromosphere and corona, to the interstellar medium in the galactic disk and halo, to planetary nebulae, and to intergalactic matter. It is shown that the principle of thermal instability is closely related to the formation of solar prominences, to condensations in planetary nebulae, and to condensation of galaxies from the intergalactic medium.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
