Effects of Preionization in Radiative Shocks. I. Self-consistent Models
Open accessAbstract
In this paper we treat the preionization problem in shocks over the velocity range 10 < v s < 1500 km s−1 in a self-consistent manner. We identify four distinct classes of solutions controlled by the value of the shock-precursor parameter, , where is the ionization parameter of the UV photons escaping upstream. This parameter determines both the temperature and the degree of ionization of the gas entering the shock. In increasing velocity, the shock solution regimes are cold neutral precursors (v s ≲ 40 km s−1), warm neutral precursors (40 ≲ v s ≲ 75 km s−1), warm partly ionized precursors (75 ≲ v s ≲ 120 km s−1), and fast shocks in which the preshock gas is in photoionization equilibrium and is fully ionized. The main effect of a magnetic field is to push these velocity ranges to higher values and to limit the postshock compression. In order to facilitate comparison with observations of shocks, we provide a number of convenient scaling relationships for parameters, such as postshock temperature, compression factors, cooling lengths, and H β and X-ray luminosity.

In the citing paper
“Given that both the midIR bands detect warm dust emission (12 µ mis warmer), the separation of the scale in these two bands can only be explained if the radiation from a shock creates a precursor region (Draine 2011; Sutherland & Dopita 2017) ahead of the shock.”

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.
