The Baseline 9: How Do Exoplanets Form? Mind The Gaps!
The Baseline 9: How Do Exoplanets Form? Mind The Gaps!
October 14, 2021 at 11:04 am | News Feature

Young stars often have disks of gas and dust around them, and many of these disks have gaps within them. How do astronomers know that these gaps are caused by young planets and not some other effect?

Early massive galaxies—those that formed in the three billion years following the Big Bang—should have contained large amounts of cold hydrogen gas, the fuel required to make stars. But scientists observing the early Universe with the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope have spotted something strange: half a dozen early massive galaxies that ran out of fuel.

An international collaboration of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) has completed the most extensive chemical composition mapping of the protoplanetary disks around five nearby young stars at high resolution, producing images that capture the molecular composition associated with planetary births, and a roadmap for future studies of the makeup of planet- and comet-forming regions. The new study unlocks clues about the role of molecules in planetary system formation, and whether these young planetary systems in the making have what it takes to host life.
