Ariel 1118-61 — A very close binary system or a slowly rotating neutron star?
Abstract
The transient X-ray source Ariel 1118-61 has a period of 6.75 min. We review possible models for the X-ray source and in particular we consider orbital and rotational origins for the periodicity. Finally we discuss the possible identification of Ariel 1181-61 with the Mira-type variable RS Cen.
