Tracing the origin of moving groups I. The {\gamma} Leo moving group
  with high resolution spectra from the Subaru Telescope
  We present chemical abundances of 15 stars in the {\gamma} Leo moving group
based on high-resolution spectra with the Subaru High Dispersion Spectrograph.
The sample was picked up by applying wavelet transform to UVW velocity compo-
nents of stars in the solar neighbourhood. Both photometric and spectroscopic
method have been used to determine the stellar parameters of stars. Abun-
dances of 11 elements including Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Y and Ba
are measured. Our results show that the member stars display a wide metallicity
distribution with abundance ratios similar to Milky way disk stars. We presume
that the {\gamma} Leo moving group is originated from dynamical effects
probably related to the Galactic spiral arms.
