Possible evidence of surface vibration of strange stars from stellar observations.

Abstract (from CDS):

Emission lines in the eV and keV range by certain stellar candidates from 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-keV excess emission in RX J170930.2-263927. Recently, it has been suggested that the resonance absorption at ∼ 0.7, 1.4, 2.1 and 2.8 keV in 1E1207-5209 and 0.35, 0.7 and 1.4 keV in RX J1856.5-3754 are due to harmonic surface vibrations in strange stars. We propose that these harmonic vibrations may also be responsible for emission lines in the above mentioned compact stellar candidates.
