ALMA Captures Stunning Images of Dusty Planet Formation Site Introduction to ALMA's Groundbreaking Observations The Atacama Large Millimeter/submillimeter Array (ALMA) has effectively captured a planet formation site, identifying a dense accumulation of dust grains — essential building blocks for planets — beyond the orbits of nascent planets. Research Team and Methodology The international research team, led by Kiyoaki Doi, a former Ph.D. student at the National Astronomical Observatory of Ja pan (NAOJ) and SOKENDAI, currently a postdoctoral fellow at the Max Planck Institute for Astronomy, conducted high-resolution ALMA observations of the proto planetary disk surrounding the young star PDS 70 at a wavelength of 3 mm. Discovering Dust Accumulation Beyond Planetary Orbits The object contains two known planets, and the latest ALMA observations have uncovered a concentrated accumulation of dust grains beyond their orbits. This discovery im plies that t...
