• Spectroscopic properties of granulation in K-type dwarf stars 

      Ramírez, Iván, 1979- (2008-05)
      The presence of surface convection in K-type dwarfs is revealed in very high quality spectra (R ≃ 180, 000, S/N &300) of nine bright stars. Relative radial velocities between pairs of spectra of the same object are ...
