由SUNY理工学院助理教授Shing-Chi Leung领导的国际研究团队发现，原始黑洞可能会触发白矮星爆炸成Ia型超新星 1。该研究通过比对Tycho、Kepler、3C 397等著名超新星遗迹以及SN 2011fe、SN 2012cg等附近超新星的观测数据，检验了这些爆炸产生的Ni-56、Ni-57等放射性同位素和Mn、Ni等稳定元素的化学特征 1。研究表明，原始黑洞触发的爆炸产生的Ia型超新星特性与标准模型相似 1。
这一发现暗示原始黑洞可能通过触发的恒星爆炸影响了银河系的化学演化 1。原始黑洞被提议作为暗物质的候选，据估计占宇宙物质质量的约90% 1。相关研究已发表于《天体物理学杂志》2026年第1004卷第2期 1。
An international research team has discovered that primordial black holes could trigger white dwarf stars to explode as Type Ia supernovae, potentially reshaping our understanding of galactic chemical evolution.1 Led by Shing-Chi Leung, an assistant professor at SUNY Polytechnic Institute, the researchers examined whether these explosions could account for chemical abundance patterns observed in supernova remnants, nearby supernovae, and stars throughout the Milky Way.1
The study compared the chemical signatures of famous supernova remnants including Tycho, Kepler, and 3C 397, as well as nearby supernovae such as SN 2011fe and SN 2012cg.1 Researchers analyzed the characteristics of radioactive isotopes like Nickel-56 and Nickel-57 alongside stable elements including manganese and nickel to determine whether Type Ia supernovae triggered by primordial black holes would produce distinct chemical patterns.1 An early 2025 paper demonstrated that explosions triggered by primordial black holes produce Type Ia supernovae with properties similar to those of standard models.1 The findings have been published in The Astrophysical Journal, volume 1004, issue 2 in 2026, with DOI 10.3847/1538-4357/ae6db7.1
Primordial black holes have been proposed as a candidate for dark matter, potentially accounting for approximately 90 percent of the universe's matter mass.1
