Using data from various space telescopes, astronomers have investigated a variable X-ray source known as SWIFT J0503.7-2819. Results of the study suggest that this source is an intermediate polar. The finding was detailed in a paper published September 22 on the arXiv pre-print server.
consisting of a white dwarf accreting material from a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Polars are a subclass of cataclysmic variables distinguished from other CVs by the presence of a very strong magnetic field in theirIn some CVs, accretion occurs through a truncated accretion disk when the white dwarf is moderately magnetic. These systems are known as intermediate polars .
"We have carried out X-ray and optical timing analyses and X-ray spectral analysis of a probable IP J0503," the researchers wrote in the paper.of approximately 81.65 minutes. Moreover, a 65.5-minute periodicity was detected and the astronomers attribute it to the spin period of the white dwarf. If this scenario is true, then J0503 would be the first nearly synchronous IP below the period gap.
