当白矮星从伴星吸积氢时,引发失控的热核反应,就会发生新星爆炸。释放的大量能量最终产生了可以用肉眼看到的明亮光源作为新星。但据预测,在反应的初始阶段,一些能量会以强烈的光度闪烁——火球阶段——以低能 X 射线的形式丢失。在本周的问题中,Ole König 和他的同事提出了证实这一预测的观察结果。使用仪器 eROSITA 进行的扫描,研究人员在新星 YZ Reticuli 中发现了短暂而明亮的 X 射线闪光,几小时后它在光谱中变得可见。封面展示了艺术家对火球阶段新星的印象。(详情见第16篇)

Nova explosions occur when a runaway thermonuclear reaction is triggered in a white dwarf that is accreting hydrogen from a companion star. The massive amount of energy released ultimately creates the bright light source that can be seen with a naked eye as a nova. But some of the energy has been predicted to be lost during the initial stages of the reaction as a flash of intense luminosity — a fireball phase — detectable as low-energy X-rays. In this week’s issue, Ole König and his colleagues present observations that corroborate this prediction. Using scans taken by the instrument eROSITA, the researchers identified a short, bright X-ray flash from the nova YZ Reticuli a few hours before it became visible in the optical spectrum. The cover shows an artist’s impression of the nova in the fireball phase.
