|Title||Is the DM Tau disk ionized by a spinning X-ray light house|
|Author||Dr Hauyu Liu|
|Description||A 3 epochs JVLA observations of the transition disk DMTau spatially resolved the distribution of free-free emission, which varied day-by-day and may be phased with the spinning of the host PMS star. The variation is interpreted by photon propagation, with the disk illuminated by beamed X-ray emission from the host PMS star, possibly due to a tilted strong stellar magnetic dipole. The JVLA Ku band A-config. and XMM-Newton monitoring for 8 consecutive days coordinated with ground based optical observations, covering one rotational period of the host PMS star, will resolve how the spatial distribution-flux of the radio emission correlate with the optical-UV-X-ray light curves|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
