A recent study presented at the National Astronomy Meeting 2023 (NAM2023) examines a newly discovered planetary formation theory that challenges previous notions on how planets are formed in the disks of gas and dust surrounding young stars, also known as protoplanetary disks. Along with being presented at NAM2023, the study has also been submitted for … Continue reading "Some Star Systems Create a Planet Sandwich"

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets. The discovery will provide astronomers with an alternate method for detecting and characterizing protoplanets when direct observations or imaging are not possible. The results will be published in an upcoming edition of The Astrophysical Journal Letters.
Relaying this from the ALMA Observatory account "over there”…
A Surprise Chemical Find by ALMA May Help Detect and Confirm Protoplanets. Located in the constellation Sagittarius, the young star HD 169142 is host to a giant protoplanet embedded within its dusty, gas-rich protoplanetary disk.

An article published in "The Astrophysical Journal" reports the results of observations of the protoplanetary disk surrounding the very young star TW Hydrae. A team of researchers used observations conducted with the Hubble Space Telescope to examine the ongoing processes and evolution of planetary formation in the system.
You had me at "Space Hurricane." :)
When new planets form in distant solar systems, they carve out space hurricanes and vortices in the surrounding dust that could lead astronomers straight to them.

Young stars are surrounded by chaos: Clouds of gas, dust and ice swirl about in a so-called protoplanetary disk. And when gravity binds this material together, planets are born. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers developed a new technique to measure and date infant exoplanets forming in these protoplanetary disks. By...
