Abstract:
The absolute elements of the system XY Ceti have been obtained on the basis of the spectroscopic elements given by Popper (1971) and the photoelectric elements derived by us. The colours of the components have been obtained. Both components are found to lie fairly on the ain sequence. The primary component of the system, however, is slightly more evolved as it shows a tendency to drift away from the main sequence. The spectral classes now assigned are A4V (primary) and A7V (secondary). The values of Roche constants indicate that the system is detached one.
