Modelling the gravity-mode period-spacing pattern of KIC 4150611's primary yields a 1.51-solar-mass, 1.1-billion-year-old star that rotates almost rigidly, contradicting the 35-million-year age from isochrone fitting.

KIC 4150611: A quadruply eclipsing heptuple star system with a g-mode period-spacing pattern Asteroseismic modelling of the g-mode period-spacing pattern
Modelling the gravity-mode period-spacing pattern of KIC 4150611's primary yields a 1.51-solar-mass, 1.1-billion-year-old star that rotates almost rigidly, contradicting the 35-million-year age from isochrone fitting.
