How do the protoplanetary disks around young pre-main sequence stars evolve into planetary systems? Come attend Dr. Catherine Espaillat’s plenary talk “From Disks to Planets: Observing Planet Formation in Disks Around Young Stars” at #AAS233 to know more!
Exquisite measurements of physical and chemical properties of protoplanetary disks from ALMA hold important clues to the history of planet formation. Come listen to Dr. Lauren Ilsedore Cleeves’ plenary lecture at #AAS233 to know more!
On the third day of Christmas the ALMA gave to me, 20 highly resolved protoplanetary disks!
It is difficult to tell if planets embedded in their natal protoplanetary disks are migrating closer to their stars. The authors of today’s paper devise a new observational signature to figure that out.
Planets form from protoplanetary disks. How they can be heavier on average than the disks is questioning our theories of planet formation.
Steep density drop-offs and orbits with high inclinations and eccentricities are just a few of the mysterious features in the outer reaches of our Solar System – can a single stellar fly-by help explain all of them?
