详细研究了在温度基本上大于10/sup 8/ K的富氢组合物中发生的核能产生和核合成。在这些高温下，一种新的核合成过程（“rp过程”）涉及种子核（或在初始金属丰度为零的情况下氦燃烧的产物）上质子的快速捕获，可以导致铁族以上的重元素的产生，伴随的能量产生率大大改变。贝塔.. -在这种计算中通常采用有限的CNO循环。新的核反应率的利益制成表格，并提出反应网络计算来说明这个过程中的应用爆炸超大质量恒星，吸积中子星星，新星，和某些混乱的宇宙学。对..的影响伽马.. -线天文学和X射线暴模型进行了讨论。
The nuclear energy generation and nucleosynthesis that occur in hydrogen-rich compositions at temperatures substantially greater than 10/sup 8/ K are examined in detail. At these high temperatures, a new kind of nucleosynthetic process (the ''rp-process'') involving the rapid capture of protons on seed nuclei (or on the products of helium burning in a situation with zero initial metallicity) can lead to the production of heavy elements up to and beyond the iron group with an accompanying energy generation rate greatly modified from that of the ..beta..-limited CNO cycle customarily employed in such calculations. New nuclear reaction rates of interest are tabulated, and reaction network calculations are presented to illustrate the application of this process to exploding supermassive stars, accreting neutron star, novae, and certain chaotic cosmologies. Implications for ..gamma..-line astronomy and X-ray burst models are discussed.
