| Abstract | V347 Aur is a young low-mass star transitioning between an evolved protostar anda cTTS that has exhibited (quasi)periodic (~155 days) optical outburts since2013. These optical brightenings signal the onset of rapid mass-infalls,magnetically channelled from the accretion disk onto the stellar surface, whichmay also produce X-ray outbursts from star-disk magnetic interaction. We predictoptical high-state/quiescent phases in 2023 August/October that will be visiblewith XMM-Newton. We propose to obtain with EPIC (2x31 ks) the correspondingX-ray spectra to investigate any changes of the physical parameters of theemitting plasma (NH, plasma temperatures and emission measures) associated withthe accretion event and the possibly enhanced star-disk magnetic interaction. |

| 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. |
