TOI-451 is a young (120 Myr) binary (or tertiary?) star system consisting of a G-type star and 1 or 2 red dwarfs located about 403.39 light-years away from the solar system, the primary star hosts 3 Neptunian planets (b= 1.91 Re, c= 3.1 Re, d= 4.07 Re). There are no current mass measurements of this system. The study also reported that they believe TOI-451 B is actually a binary of two equal-mass red dwarfs, but that's all they said about it.
