Abstract：
the nuclear processes in astrophysics are briefly reviewed, and the explosive hydrogen burning are addressed and calculated with some new reaction rates obtained from the most recent experimental data. We pointed out that the reaction flux from the hot pp–chain into the CNO cycle through the proton capture on ¹¹C may overcome the flux through the 3α process. the abundance of ¹⁸F calculated with the new rates of the ¹⁸F(p, γ) and (p,α) is 1.8 times larger than the previous one. The calculated results of the rp–process at the typical condition of the X-ray burst show that the abundances of the waiting point nuclei ⁸⁹Ru and ⁹³Pd, using the recent experimental β–decay life times, are about 4 times larger than the previous ones.
