Abstract
We collect the recently published data of twin kilohertz quasi-periodic oscillations (kHz QPOs) in neutron stars (NSs), and analyze two kinds of samples for five Atoll sources and five Z sources. We study the the relation between the quality factor and the peak frequency of upper frequency. We take three possible models, i.e. linear, power-law and exponential models to fit the data and find that the power-law and the exponential models can reflect the relation better than the linear model.
