Wolf 1069 is another nearby red dwarf with an exoplanet, but this time, the exoplanet is more likely to harbor life than other nearby red dwarfs with exoplanets that I may have discussed in previous episodes.

Algol-type variable affected by light travel time effect caused by two smaller red dwarfs on wide orbits; this makes the variability period of the central two stars appear to vary.
