Otero, Sebastian Alberto
|
Eccentric system. Min II= 8.51V at phase 0.52. Apsidal motion with P ~10400 yrs. Tidally excited oscillations with P= 1.869 and 1.673 d. that show an obvious beat phenomenon with a period that is equal to half of the orbital period. Another sinusoidal light variation is also observable with a period equal to half-orbital period, and phased in such a way that the maximum brightnesses occur near orbital phases 0.0 and 0.5 (i.e. near the eclipses). Therefore, this enigmatic variation looks like an ‘inverse’ ellipsoidal effect, or resembles a reflection or irradiation effect, although its high amplitude clearly excludes this latter explanation.
