Abstract

Nucleosynthesis is investigated inside an accretion disk around a black hole of 50 - 10³M_⊙ located in a circumnuclear region of starburst galaxies. Nuclear reactions proceed through the hot CNO cycle to produce large amounts of ¹⁴O and ¹⁵O, which decay to ¹⁴N and ¹⁵N. The calculated N/O - O/H relation is found to be consistent with that observed in the most metal-poor galaxies. The accretion disk may be one of the promising sites of nitrogen production.
