List of cyclotron line sources

Source list

This table attempts to summarize all known cyclotron line sources. It is sortable by clicking on column headers.

It is based on the presentation ["Spectral continua of accreting neutron star systems"] by Jörn Wilms at the conference [of Neutron Stars 2010] with some information added later.

Location in the Galaxy

The figure below displays the position of the sources listed above in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. The spiral arms are from [(:biblio:Vallee08)].
