Scientific paper

The Trapezium Cluster at the center of the Orion Nebula Cluster (ONC) is one of the youngest and closest (440 pc) star-forming regions. Many of the properties we know today are derived from X-ray signatures. Here we study highly resolved X-ray spectra of a large ensemble of very young and chemically similar PMS stars in terms of their magnetic and accretion properties. This is the second of three installments of our Orion HETG program, the first one was for 100 ks in AO6, a third one for 150 ks will follow in AO9. In these pointings we add more counts to our current sample of Orion stars, which so far include 4 spectra of massive Trapezium stars and 2 late-type PMS stars. A series of 6 pointings will result in at least 6 additional PMS spectra and higher quality Trapezium spectra.
