Hi Marc & Robin,
the observer group (see attachment) is going to continue their HR observation of the V&R component in order to catch the moment of the beginning of its eclipse. It seems that the peak height of the V component decreases already “for some time”.
If this “effect” is true, then that does it mean, either the disk of the B star or the photospheric wind of the M star (or both) is larger than assumed until now. But we have to wait and see. In that context I am interested to get your spectrum. Would you be so friendly to send me it?
Best wishes, Ernst
