Possible evidence of surface vibration of strange stars from stellar observations
Emission lines in the eV and keV range by certain stellar candidatesfrom their recent analysis invoke the question of their possible origin.The stars under consideration are 4U0614+091 (0.65, 0.86 and 1.31 keV),2S 0918-549 (0.8 keV with width 55 eV), 4U 1543-624 (0.7 keV), 4U 1850-087 (0.7 keV) and 4U 1820-30 (0.6 and 0.9 keV) and also the 0.6-keVexcess emission in RX J170930.2-263927. Recently, it has been suggestedthat the resonance absorption at ~ 0.7, 1.4, 2.1 and 2.8 keV in1E1207-5209 and 0.35, 0.7 and 1.4 keV in RX J1856.5-3754 are due toharmonic surface vibrations in strange stars. We propose that theseharmonic vibrations may also be responsible for emission lines in theabove mentioned compact stellar candidates.
