Theoretical and observational investigations have provided convincing evidence for th e formation of molecular cloud cores by the gravitational fragmentation of filamentary molecular clouds\, which has important implication for the or igin of the stellar initial mass function. On the other hand\, the size an d total angular momentum of a protoplanetary disk are supposed to be direc tly related to the rotational property of the parental molecular cloud cor e where the central protostar and surrounding disk are born. Our recent an alysis concludes that both the mass function and angular momentum distribu tion of molecular cloud core are the natural outcome of transonic turbulen ce with Kolmogorov spectrum in parental filamentary molecular clouds. The implication of this identification is non-homogeneous angular momentum dis tribution inside a molecular cloud core. The actual angular momentum accre tion onto a young stellar object in the core should create misalignment of disk surrounding the star. We show the probability distribution of the mi salignment as a function of disk mass. This finding may explain the origin of misaligned planets created in those disks.\n\nhttps://meetings.aip.de/ event/1/contributions/43/ LOCATION:Leibniz Institute for Astrophysics Potsdam (AIP) Lecture Hall URL:https://meetings.aip.de/event/1/contributions/43/ END:VEVENT END:VCALENDAR
