    • a Adiabatic (Physics) Not giving out or receiving heat.☞The adiabatic expansion of carbon dioxide from a compressed container causes the temperature of the gas to decrease rapidly below its freezing point, resulting in the familiar carbon dioxide “snow” emitted by carbon dioxide fire extinguishers.

X Y chains obtained within the continued-fraction approach may be of use for the study of the spin-Peierls instability in these chains in adiabatic limit.
Thermodynamic properties of the periodic nonuniform spin-1/2 isotropic XY chains in a transverse field
Similarly, magnetic fields may change their configuration and orientation in space (e.g. due to Alfven waves), but if the time for such a change is much longer than the Larmor period the alignment of grains in respect to the field lines persists as the consequence of preservation of the adiabatic invariant.
Physics of Grain Alignment
Thus the atmosphere has a nearly adiabatic pro file when convective.
Rotational Evolution During Type I X-Ray Bursts
For the convective zone, we integrate dT /d y = n(T /y) for a given base temperature Tb (the super-adiabaticity needed to carry the flux in the convective zone is negligible when the convection is so efficient; see Cox & Giuli 1968).
Rotational Evolution During Type I X-Ray Bursts
In addition, we have ttherm ≈ tE , so non-adiabatic effects may be important, reducing the effect of the thermal buoyancy (Sakurai et al. 1971).
Rotational Evolution During Type I X-Ray Bursts
The difference in slope of the convective adiabat between models is due to the differing contribution of radiation pressure.
Rotational Evolution During Type I X-Ray Bursts
In these model universes both the ordinary matter, the adiabatic perfect fluid, and the scalar field, are equally important, and one of the main enigmas to be resolved in this context is why the energy density of the additional quintessence matter almost co-incides with the usual matter density today [3, 5].
Exact Inflationary Solutions from a Superpotential
W ′ (φ) here one must assume that the “adiabatic” index of the perfect fluid model describing the scalar field is constant .

In the case when a set of slow (adiabatic) variables can be chosen, our formalism yields a general form of the macroscopic evolution law (Generalized Langevin Equation) and extends Fluctuation Dissipative Theorem.
Generalized Entropy approach to far-from-equilibrium statistical mechanics
This approach assumes the possibility of choosing a set of relatively slow (adiabatic) variables.

In this Letter, we further investigate this result showing that, using the CMB data alone, a purely baryonic adiabatic model of structure formation seems unlikely if the universe is flat (Ω = 1).
CMB Constraints on a Baryonic Dark Matter-Dominated Universe
As is well known, purely baryonic adiabatic models are in severe contradiction with the measured amplitude and shape of galaxy and cluster correlations.
