12 Mar 2019 | Abstract: | The processes that transform gas and dust in circumstellar disks into diverse
exoplanets remain poorly understood. One key pathway is to study exoplanets as
they form in their young ($sim$few~Myr) natal disks. Extremely Large
Telescopes (ELTs) such as GMT, TMT, or ELT, can be used to establish the
initial chemical conditions, locations, and timescales of planet formation, via
(1)~measuring the physical and chemical conditions in protoplanetary disks
using infrared spectroscopy and (2)~studying planet-disk interactions using
imaging and spectro-astrometry. Our current knowledge is based on a limited
sample of targets, representing the brightest, most extreme cases, and thus
almost certainly represents an incomplete understanding. ELTs will play a
transformational role in this arena, thanks to the high spatial and spectral
resolution data they will deliver. We recommend a key science program to
conduct a volume-limited survey of high-resolution spectroscopy and
high-contrast imaging of the nearest protoplanetary disks that would result in
an unbiased, holistic picture of planet formation as it occurs. | Source: | arXiv, 1903.5077 | Services: | Forum | Review | PDF | Favorites |
