A Note on the Discovery of Absorption Features in 1E 1207.4-5209

Sanwal et al. Astrophys. J. 574 (2002) L61 supposed that it is very difficult to interpret the absorption features in terms of cyclotron lines. However, we would like to address here that the possibility of the absorption being cyclotron resonance cannot be ruled out. We propose that the isolate neutron star, 1E 1207.4-5209 in the center of supernova remnant PKS 1209-51/52, has a debris disk and is in a propeller phase, with an accretion rate ～ 6 x 10^-11M/year. In this scenario, 1E 1207.4-5209 could also be a bare strange star.
