同步恒星驱动宇宙射电激光

研究人员揭示了某些恒星对产生周期性长波段射电波爆发的机制。这些天体系统由一颗白矮星与一颗M型矮星组成，两者相互绕转。

Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects they observed come in pairs that always include a compact dead star, called a white dwarf, locked in orbit with an M dwarf, a red star smaller than our Sun.
