| Description |
We propose to use the three instrument on board Herschel to carry out a comprehensice study of the star forming region IRAS23385+6053.The region is a well-known template to host an intermediate-high mass young stellar object possibly on the verge of reaching the ZAMS. This massive YSO, detected as a strong peak in the millimeter but unrevealed below 20um, is surrounded by a population of lower mass objects of both intermediate and low mass in different evolutionarystages, and offer ideal conditions to map the star formation history in a typical region. We will determine accurate Spectral Energy Distributions and luminosities for all the compact objects, and will also ascertain if the region is at the crossroads of intense filamentarystructure. Spectral maps with PACS will be obtained in OI and CII, and together with other tracers from the SPIRE FTS spectral range we will be in the ideal conditions to obtain a fairly comprehensive and definitive view of the FUV irradiation conditions in the region. This will provide definitive conclusions regarding the evolutionary stage of the different YOSs in the region, enabling to draw a plausible star formation history. |
