We analyzed the kinematic of 12 low surface-brightness (LSB) galaxies to study the correlation between the disk circular velocity V_c and the central velocity dispersion of the spheroidal component σ_0. This relation has been claimed to be either the same power-law relation or a different linear one with respect to high surface-brightness (HSB) galaxies. We confirm here that LSB and HSB galaxies follow two different linear V_c-σ_0 relations.

Abstract
We analyzed the kinematic of 12 low surface-brightness (LSB) galaxies to study the correlation between the disk circular velocity V_c and the central velocity dispersion of the spheroidal component σ_0. This relation has been claimed to be either the same power-law relation or a different linear one with respect to high surface-brightness (HSB) galaxies. We confirm here that LSB and HSB galaxies follow two different linear V_c-σ_0 relations.File in questo prodotto:
