| dc.description | We have discovered a new AM Her system as the optical counterpart of the ROSAT All-Sky-Survey source RX J1016.9-4103 (= 1RXS J101659.4-410332). The X-ray spectrum is very soft and the X-ray intensity is strongly modulated with the orbital period. Optical photometric and spectroscopic follow-up observations reveal a synchronously rotating binary with an orbital period of 134 min, placing RX J1016.9-4103 in the period gap. The strength of the TiO bands suggests a secondary spectral type later than M3 V and a distance of 615+/-150 pc. Based on two clearly visible broad humps in the optical spectrum (interpreted as cyclotron features) a magnetic field strength of 52 MG is deduced thus proving the polar classification. | |
