Finding periods in the high mass x-ray binary stars of the magellanic clouds

High Mass X-Ray Binary Stars (HMXBs) are stars that contain one early-type
main sequence or giant star and one of a black hole, neutron star or white dwarf.
HMXBs in the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud
(SMC) are instructive to study because both galaxies are metal poor in compari-
son to the Milky Way and they are fairly transparent to both optical and X-ray
radiation. This allows a more complete study of the whole population, without the
biasing effects of gas and dust that occur in our own Galaxy. The objective of this
study was to find the periods of HMXBs in the LMC and SMC with known optical
counterparts in the dataset acquired by the Robotic Optical Transient Search Ex-
periment telescope. Two possible orbital periods were found for the objects XTE
J0055-724 and RX J0101.3-7211 of 1724 days and 478 days, respectively. Continued
observations are recommended to conrm the two periods.
