Merope is one of the major members of the Pleiades cluster. As with the other members of the Pleiades, both major and minor, Merope is approximately 115 million years of age. We know from observations that it is a 14000K spectral type B6 subgiant star. Like most of the other primary members of the Pleiades, it rotates rapidly, leading to the star having a highly oblate ellipsoid shape, rather than being more or less spheroid like a typical star. In fact, Merope spins so rapidly that not only is its shape distorted but a diffuse disk of plasma (a decretion disk, the opposite of an accretion disk!) exists around its equatorial region.
