Scientific paper

The HST Treasury program on the Orion Nebula, currently in execution, has surprisingly found that background sources are easily detected by HST at long wavelengths through selected fields within the nebula. We propose to use these background sources as a reference system to measure the trigonometric parallax of the Orion Nebula cluster. Using ACS in the F850LP filter and with a modest investment of HST time, we will reduce the error on the 500pc distance of the Orion Nebula to 15pc, or less, improving by a factor 6 over current estimates. Our new value will have a major impact on star formation studies, allowing to determine with high accuracy the absolute luminosity of the cluster members and all derived stellar parameters {ages, masses, mass accretion rates...}. Our current understanding of a great range of phenomena associated to the star formation activity in Orion will also benefit from an improved distance estimate.
