PRIMA will fill an essential gap between ALMA and JWST for understanding disk structure and dissipation

PRIMA will combine with other observatories to better understand protoplanetary disks

000

PRIMA probe @prima-probe.bsky.social · 19/05/2025

Understanding the radiation environment in disks and its role in their evaporation is key to understanding disk evolution. PRIMA will provide essential information on high-energy radiation through multiple lines like OI, greatly expanding on samples of a few lines measured with Herschel

#PRIMA2025 Working Meeting: Day 1! We're welcoming >350 scientists to discuss @prima-probe.bsky.social's possibilities! The response to the three-day hybrid event was so outstanding we moved it to a bigger venue. Today's topics: project overview, protoplanetary disks, time domain astro, & stars.

However, the sample of edge-on disks available for these studies is limited and intrinsically biased. Far-IR observations, which are not restricted to edge-on disks, offer a unique path to a gaining complete understanding of the demographics of icy disks.

The shape of these protostellar disk ice spectra can yield detailed information about the quantity of ice and its chemical composition and environment.

PRIMA probe @prima-probe.bsky.social · 19/05/2025

Near- and mid-IR spectra of disks are revealing ice properties, but these disks must be observed edge-on. Interpretations of these observations are very sensitive to radiative transfer, and require good models of disks and accurate lab measurements of optical ice properties.

PRIMA probe @prima-probe.bsky.social · 19/05/2025

ALMA is making great progress characterizing the dust grain content, but we are currently missing a way to characterize the icy component of disks, which carries the bulk of planet-forming materials, including key ingredients like volatiles and prebiotic molecules

PRIMA's capabilities are defined by a PI science program, but they are ultimately designed to deliver a powerful and flexible community resource, with 75% of PRIMA's observing time (~32,000 hours over 5 years) open to astronomers everywhere

PRIMA is designed to be a community resource. You can help make it a reality by contributing to PRIMA's GO science book.

Decades of NASA investment have enabled this enormous technological leap forward, yielding an orders of magnitudes increase in observing capabilities in the far-infrared that is equivalent to observing at optical wavelengths at night vs. day
