论文摘要
我们报告了强磁场对修饰的URCA过程中中微子发射的影响。我们表明，Landau水平对各种URCA对的影响会影响中微子的发射光谱，并导致中微子发射中的角度不对称。对于低磁场，Landau水平几乎对冷却没有影响。但是，随着场强的增加，电子化学势会增加，从而导致较低的urca对可能存在。对于中间场强，Landau水平分布与费米分布之间存在有趣的干扰。对于足够高的磁场强度，整个电子能谱最终仅限于单个Landau水平，在发射光谱中产生戏剧性的尖峰。
We report on the effects of strong magnetic fields on neutrino emission in the modified Urca process. We show that the effect of Landau levels on the various Urca pairs affects the neutrino emission spectrum and leads to an angular asymmetry in the neutrino emission. For low magnetic fields the Landau levels have almost no effect on the cooling. However, as the field strength increases, the electron chemical potential increases resulting in a lower density at which Urca pairs can exist. For intermediate field strength there is an interesting interference between the Landau level distribution and the Fermi distribution. For high enough field strength, the entire electron energy spectrum is eventually confined to single Landau level producing dramatic spikes in the emission spectrum.
