Description There is growing evidence that the star formation process is in fact highly dynamic, on timescales from days to centuries. The temporal variability is a new and powerful diagnostic tool to study Young Stellar Objects (YSOs). Depending on the timescale of the variability in the mid and farinfrared we can learn about different physical mechanisms shaping their structure and dynamics. Here we propose to extend our near and midinfrared study of variable YSOs in the young open cluster IC 348 to the farinfrared (70 and 160 micron) using Herschel-PACS. We will constrain the frequency of farinfrared variability and compare the observed timedependent behavior with protostellar and disk models to understand its origin. Possible mechanisms include fluctuations in the accretion luminosity, or echoes of inner disk structural changes projected onto the infalling envelope or flared outer disk surface. Our sample in IC348 covers a large part of the evolutionary sequence of YSOs from class I sources to transitional disks. The cadence of the requested observations allow us to study variations on time scales from days to months that could be extended to several years using our Spitzer-MIPS data.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
