Scientific paper

We present the results of the Virgo high-resolution CO survey (VCOS) obtained with the Nobeyama Millimeter-wave Array at high-angular and spectral-resolutions in the 12CO (J = 1 - 0) line emission for 15 Virgo CO-rich spirals. The central CO distributions can be classified into the ``central/single-peak type", which is a majority, and ``twin-peaks". We derived exactrotation curves by applying a new iteration method to position-velocity diagrams, which show generally a steep central rise, indicating central massive cores.
