Description We propose a survey of five nearby Bok globules to search for X-rays from Class 0 protostars. X-rays from Young Stellar Objects are likely to originate from the near vicinity of the star itself. The detection of the X-rays from Class 0 protostars, therefore, is of particular importance, providing direct evidence that the central star has been born. However, the protostars are usually deeply embedded within the cloud, so that, even the X-rays were completely absorbed. Bok globules are known as star formation sites surrounded by light and small molecular clouds of 10 Mo. The small absorption column of Bok globules gives us an opportunity to search whether X-rays "turn-on" occurs during the Class 0 phase and if so, when?

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.
