Observing the earliest stages of star and planet formation

A while ago I wrote a post about an ALMA observation of a very young stellar object (Elias 2-27) that shows spiral density waves in its circumstellar disc (see Figure on the right). A reason I wrote that post is … Continue reading

Spiral density waves

There was an interesting (non-climate) paper in Science, by Laura Perez and colleagues, about Spiral density waves in a young protoplanetary discs. Essentially, they used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to observe a young stellar object (Elias 2-27) in … Continue reading
