The Impact of Multiplicity in Young Stars on Disk and Planet Formation

<![endif]-->While the majority of stars are formed in multiple systems, the impact of stellar
companions on the formation and evolution of protoplanetary disks is not well quantified.  As
the disk also serves as the reservoir from which planetary systems may form, multiplicity will
also have an impact on planet formation around these stars.  With the arrival of ALMA, we
can now measure disk masses around many more young stars and examine
the role of multiplicity.  I will present results from an ALMA survey of young stars in Taurus
and examine the disk mass as a function of stellar mass and multiplicity.
I will also discuss using ALMA data to determine the relative alignment of disks in multiple
systems and the implications for planetary orbits.
