Ramanpreet Kaur : Chandra and XMM-Newton observations of 7 enigmatic faint persistently slow pulsators

The author presented the analysis of two (out of seven) faint slow pulsators with period greater than 150 sec, precluding that they belong to the HMXB, LMXB or IP (intermediate polar) class. Using XMM and Chandra, spectral, timing and positional data were obtained in order to classify the source. The first source, SAX J2324.4-6200, is most probably a Be/X-ray source (HMXB) based on the X-ray spectrum or an very uncommon LMXB. The second slow pulsator, SAX J1452.8-4959 shows no pulsation and have a very faint counterpart, suggesting a possible LMXB or IP classification. However, the timing analysis is uncertain, indicating that the source could be of a different class (e.g CV, background AGN, ...). The X-ray to optical/IR flux ratio for these sources is not known yet.
