Dr. Hallas is an ssociate professor at the Department of Astronomy at Boston University.
We know that many pre-main-sequence stars are surrounded by protoplanetary disks, but how these disks evolve into planetary systems is a fundamental question in Astronomy. Young stars and their disks are known to be remarkably variable, but it is not clear how this variability may influence planets as they are forming. This talk will review key observations of protoplanetary disks and their young stars, focusing on multi-wavelength variability linked to accretion onto the star. To conclude, I will discuss possibilities for future progress in time-domain studies of these young systems.
