\n Collection of disks with localized asymmetries in the dust continuum emission, shown at the same spatial scale based on the Gaia DR3 parallax. The colorscale is chosen arbitrarily to highlight the substructures. These images were presented in Ragusa et al. (2021) (IRAS 04158+2805), McLachlan et al. (2026) (AT Pyx), Pinilla et al. (2022) (LkHa 330), Francis & van der Marel (2020) (HD 34282), Vioque et al. (2026) (HD 97048, J16070854), Isella et al. (2018) (HD 163296), Hashimoto et al. (2021a) (ZZ Tau IRS), Norfolk et al.

The Atacama Large (sub-)millimeter Array (ALMA) has been in scientific operations for almost 15 years.<\/p>\n

We celebrate this achievement by providing a summary of the \u201cDisks and planet formation\u201d scientific category, with an emphasis on the disks located in the nearby star-forming regions.<\/p>\n

As of the beginning of February 2026, ALMA had observed 3933 independent coordinates, which we analyzed by their location in the sky, frequency coverage, exposure time, spectral line coverage, and angular resolution.<\/p>\n

We encourage the community to explore new scientific questions that are made possible through the archival datasets.<\/p>\n

The Atacama Large Millimeter\/submillimeter Array (ALMA) has been in operation since 2011. This timelapse shows the first observation date and total exposure time for all entries in the ALMA Archive within the scientific category \u201cDisks and Planet Formation\u201d. These observations are summarized in Kurtovic et al. (2026b): \u201cAn archival summary: 15 years of ALMA observations on disks and planet formation\u201d. The star-forming regions are labeled following Delfini et al. (2025), based on the catalog of Avedisova (2002).

A sequence of images from the ALMA telescope, with observations of the dust continuum emission from planet forming disks, after deprojecting by inclination and position angle. In the central image, all the disks are shown at the same spatial scale. The orbits of the planets in our Solar System are presented at the beginning for size reference. The insert on the bottom left shows the original image from ALMA, with the image extent changing from disk to disk to adjust for the disk size. All these images and their bibliographic references can be found in Kurtovic et al. (2026b): \u201cAn archival summary: 15 years of ALMA observations on disks and planet formation\u201d.

Collection of disks with substructures in dust continuum emission, available in the literature. Each panel is 400 au in size, and the disks are scaled based on the Gaia DR3 parallax, ranging from largest to smallest continuum disk from top to bottom. Further details and references in Sect. C. \u2014 astro-ph.EP<\/p>\n
