Observing with ESO Telescopes . ... ESO-MIDAS . ... Using a robust method to identify Pre-Main Sequence (PMS) stars through their photometric excess in the Hн± band, we have recently studied the star formation history in several star burst clusters in the Galaxy, Small and Large Magellanic Clouds. ...

All stars derive their energy through the thermonuclear fusion of light elements in to heavy elements. High temperatures are required so that the mutual electrostatic repulsion of the protons in each fusing atomic nucleus is overcome. ...

Next: X--ray Activity and PMS stars . ... This has made the need to study the evolution of the rotation periods of stars, and hence the angular momentum, very clear. ... In the case of low mass pre--main sequence (PMS) stars, we seek to learn whether disks alone determine the angular momentum distribution when stars arrive on the main sequence. ... If one assumes that angular momentum is conserved from the natal cloud, then rotation periods exceeding breakup velocity are implied for PMS stars. ...

... A GB (GB1 and GB2) code is a two byte code, where the first byte is in the range $21-$77 (hexadecimal), and the second byte is in the range $21-$7E. A graphical ASCII character is a byte in the range $21-$7E. A non-graphical ASCII character is a byte in the range $0-$20 or of the value $7F. Since the range of a graphical ASCII character overlaps that of a GB byte, a byte in the range $21-$7E is interpreted according to the mode it is in. ... This code switches the mode from GB back to ASCII. ...
