Chronology of planet formation

In the remainder of the chapter we review the major stages and key open questions of planet formation, drawing on the detailed discussions presented in the subsequent chapters. 

Jets and outflows common (Bally etal. 2006 Ray etal. 2006) 

Fe initial SS abundances (Oulette et al. 2007 Mostefaoui et al. 2005) 

Taurus-Auriga (age spread) 0-4 Myr Radial disk structures and gaps detected 

IC 348 and Chamaeleon I star-forming regions 2 Myr, warm dust disks around -50-65% of stars (Luhman 2008)
