Teams using our ALMA Observatory have been able to clearly show how magnetism has a pre-eminent role in young star accretion and growth!
The best part is that the lead scientist for that paper is our colleague Paulo Cortés, who apart from doing notable science is also responsible for the scientific acceptance of ALMA software releases!

New ALMA observations reveal spiral-shaped gas streamer guided by magnetic fields in a star-forming nursery Highlights A team of astronomers led by Paulo Cortes, a scientist with the U.S. National Science Foundation National Radio Astronomy Observatory and the Joint ALMA Observatory, has made a groundbreaking discovery about how young star systems grow. Using the powerful...
Of course all of this builds on the initial success from the original ALMA long-baseline campaing that looked at HL Tau and found its protoplanetary disk in all its glory…

A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart[1. Since September 2014 ALMA has been observing the Universe using its longest...
Using data from ALMA and advanced simulations, a research team led by Santiago Orcajo from the Instituto de Astrofísica de La Plata in Argentina (CONICET and Universidad Nacional de La Plata) has presented a new model that traces the evolution of protoplanetary disks through five distinct stages. The results strongly support a planet-driven origin of these substructures and offer new insights into how planets interact with the disks in which they form.
Stage I: Very young disks with shallow or no obvious substructures, corresponding to an epoch in which protoplanets are not massive enough to carve noticeable gaps in the disks.
Stage II: Disks with relatively narrow, but clear gaps and rings, indicating the growth of protoplanets
Stage III: A rapid widening of the gaps due to the sudden growth in the mass of some planets when they acquire their gaseous envelopes. This stage includes the rapid accumulation of dust at the outer edges of the gaps (the inner rims of the outer disks) due to the strong “pressure bumps” caused by the giant planets that recently formed, which stops the inward drift of dust.
Stage IV: Dust filtration at the edges of the cavities, resulting in dust-depleted inner disks. The millimeter dust from the outer disks efficiently drifts in and accumulates at the edges of the gaps.
Stage V: Eventually, the dusty inner disks drain completely onto the stars, and the outer disks become narrow rings (or collections of narrow rings).

By combining ALMA observations and simulations, the ODISEA team traces how planets may form and reshape their disks Ever since ALMA captured the striking image of HL Tau in 2014, revealing intricate rings and gaps in a disk around a newborn star, astronomers have sought to understand how such complex structures could emerge so early. The...
An international collaboration called exoALMA is using our telescopes to s peer through the dusty disks where planets are born. Thanks to their newly developed advanced imaging techniques, exoALMA has revealed the most sharp images of young solar systems, as never seen before. This research project has just published 17 papers, with several more coming on the several months.
The exoALMA collaboration is using ALMA to conduct a comprehensive planet hunting campaign in the sub-mm regime. They claim to be the first to focus on still-forming planets, instead of fully formed ones.
Unlike traditional planet-hunting methods that look for a young planet's direct light, exoALMA looks for the effects planets have on their surroundings. This approach potentially allows to detect much younger planets than ever before. "It's like trying to spot a fish by looking for ripples in a pond, rather than [the] fish itself.”

An international scientific team have embarked on an exciting new project to hunt for planets forming around young stars. The exoALMA project, using the powerful Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, is peering into the dusty disks where planets are born. Thanks to newly developed advanced imaging techniques, exoALMA has revealed the most sharp...
Maybe it is just four teams that is meh. I think six teams would have been ideal. Add a #European team and another #NorthAmerican #YoungStars now you have something. Have a feeling I'll end up not watching and just catching the #highlights.Dropping in with your 2024 #YoungStars schedule 🫡
The annual prospects tournament, taking place in Penticton, BC, will feature #Flames games being streamed on http://CalgaryFlames.com!
