论文摘要
软伽马中继器（SGR）的光度显着超过了爱丁顿的光度。这是因为它们主要在电子模式中散发出来，为此，辐射横截面得到了强烈抑制。能量在磁层中释放，形成磁性的一对火球，恒星的表面被火球的强大辐射照亮。我们通过这种辐射研究了从表面的消融。电子模式光子散布在表面层中，部分被转换为O-Photon，其散射横截面是汤姆森横截面的顺序。 O模式辐射的高辐射压力向上排出血浆。隆隆的物质在火球周围形成了厚实的巴属鞘。如果恒星表面的照明部分包括极盖，则会形成沉重的相对论性的重型式风风。
The luminosity of the Soft Gamma Repeater (SGR) flares significantly exceeds the Eddington luminosity. This is because they emit mainly in the E-mode, for which the radiative cross-sections are strongly suppressed. The energy is released in the magnetosphere forming a magnetically trapped pair fireball, and the surface of the star is illuminated by the powerful radiation from the fireball. We study the ablation of the matter from the surface by this radiation. The E-mode photons are scattered within the surface layer, partly being converted into O-photons, whose scattering cross-section is of the order of the Thomson cross-section. The high radiation pressure of the O-mode radiation expels the plasma upwards. The uplifted matter forms a thick baryon sheath around the fireball. If an illuminated fraction of the star's surface includes the polar cap, a heavy, mildly relativistic baryonic wind is formed.
