The Frontiers of Solar System Formation
from the VLA, ALMA, and JWST
John Tobin - NRAO -
Abstract: The origins of solar systems are a tantalizing story that helps us understand our own origins
and the likelihood of life elsewhere. It is impossible to witness the full formation of a solar system from gas cloud to a star with planets because the process takes millions of years. However, leading observatories like the Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA), and JWST provide snapshot views of newborn stars that enable us to reconstruct the sequence of solar system formation and learn about the origins of own Solar System. The capabilities of these telescopes go beyond just capturing images, sensitive spectrometers on ALMA and JWST can detect the chemical fingerprints that reveal the origin of water and molecular complexity at the time of star and planet formation, essential ingredients for the ultimate formation of life. Still, the next generation of instruments in development have the promise to stretch our knowledge of solar system formation even farther, possibly enabling some processes to be observed in near real time. -
