"Molecular spectroscopy of planet-forming regions: A quest to understand the diversity of planets and planetary systems" We have long known about the great diversity of environments found
within the solar system. Now, thanks to radial velocity and transit
detections of exoplanets, we know that planetary systems display a
great variety of architectures. How do each of these systems come to
be, and did the solar system follow a common or unusual path towards
producing a planetary system capable of sustaining life? Although
planetary observations and meteorite samples provide detailed
information about some aspects of the solar system's origins, these
techniques are limited to examining the fossil remnants of the
formation process. Observations of protoplanetary disks around young
stars, on the other hand, allow us to view planetary systems as they
form, and to determine the relative uniqueness of the early solar
system environment. These observations face many technical challenges
and to-date we have studied only the most basic characteristics of
disks. However, we are transitioning into an age where detailed
structure and chemistry can be studied, informing us about the
diversity of initial conditions for planet formation. I will discuss
the role that molecular spectroscopy has played in effecting this
transformation, both in providing a clever means to study disk
structure on scales smaller than the true spatial resolution, and in
providing a means to study disk chemistry. I'll discuss some of what
we've learned to date about disks, and highlight some of the most
exciting current projects, such as the use of multi-wavelength
datasets to create chemical "maps". Finally, I'll discuss the future
of molecular spectroscopy and what I hope we'll learn with the next
generation of facilities including ALMA, JWST and GMT. National Optical Astronomy Observatory (NOAO) host: Sally Dodson-Robinson |
