Abstract (from CDS):
The single-lined binary nature of the star, together with the mass function, lead us to conclude that the orbital inclination must be larger than 10°. The orbital solution is compatible with a synchronized M3V companion. The deformation of the primary due to tidal forces is very probably the reason for the failure of detailed seismic modelling efforts done recently.
