Jaisawal Physical Research Laboratory, Ahmedabad Abstract Type : Oral Abstract Category : Stars,ISM and the Galaxy Abstract : Cyclotron resonance scattering features (CRSF) are unique features detected in the broad-band X-ray spectra of accretion powered X-ray pulsars. Detection of these features provides us a direct estimation of the surface magnetic field of the neutron stars. Corresponding to magnetic field of ~10^12 G, the fundamental lines are expected in 10-100 keV energy range with harmonics expected at multiples of fundamental line energy. However, we detected first harmonics of cyclotron line at less than twice of the fundamental line energy in a few X-ray binary pulsars. With the broadband spectral capability of X-ray observatories such as Suzaku, NuSTAR etc., we have investigated the CRSF in several X-ray pulsars to understand characteristic properties of such lines. The results obtained from our studies of CRSF in X-ray pulsars will be discussed. |
