| Abstract: | We discuss the origin, evolution and fate of low-mass Algols (LMA) that have components with initial masses less than 2.5 M0. The semi-major axes of orbits of pre-LMA do not exceed 20–25 R0. The rate of formation of Algol-type stars is  0.01/year. Magnetic stellar winds may be the factor that determines the evolution of LMA. Most LMA end their lives as double helium degenerate dwarfs with M1/M2 0.88 (like L870-2). Some of them even merge through angular momentum loss caused by gravitational waves. |
