| Abstract | The SMC is hosting more than a hundred HMXBs, all but one with Be companion stars, and for half of them pulsations were discovered. During the calibration phase of the eROSITA instrument, the Be/X-ray binaryXMMUJ010429.4-723136 was observed and its pulsations were detected for the firsttime, at 164s. The I-band OGLE light curve indicates a brightening of the sourcehappening in 2012, also matching with higher X-ray fluxes measured since then.Only eROSITA performed long observations of the source since 2012, enabling thedetection of pulsations. We are requesting 30ks observations with XMM-Newton, inorder to confirm the long term spin-up trend suggested by the eROSITA data,possibly connected with the X-ray and optical brightening of the source from this last decade. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
