Debris disk around AU Mic imaged by JWST

Summary

DescriptionAU Mic Compass (NIRCam).png	English: These coronagraphic images of a disk around the star AU Microscopii, captured by Webb’s Near-Infrared Camera (NIRCam), show compass arrows, scale bar, and color key for reference. The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above). The scale bar is labeled in astronomical units, or A.U., which is the average distance between the Earth and the Sun. The field of view shown in this image is approximately 100 A.U. across. This image shows invisible near-infrared and mid-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter.

Image title	These two images are of the dusty debris disk around AU Mic, a red dwarf star located 32 light-years away in the southern constellation Microscopium. The team used Webb’s Near-Infrared Camera (NIRCam) to study AU Mic. NIRCam’s coronagraph, which blocked the intense light of the central star, allowed the team to study the region very close to the star. The location of the star, which is masked out, is marked by a white, graphical representation at the center ofeach image. The region blocked by the coronagraph is shown by a dashed circle.Webb provided images at 3.56 microns (top, blue) and 4.44 microns (bottom, red). The team found that the disk was brighter at the shorter or“bluer” wavelength, likely meaning that it contains a lot of fine dust that is more efficient at scattering shorter wavelengths of light.The NIRCam images allowed the researchers to trace the disk, which spans a diameter of 60 astronomical units (5.6 billion miles), as close to the star as 5 astronomical units (460 million miles)– the equivalent of Jupiter’s orbit in our solar system. The images were more detailed and brighter than the team expected, and scientists were able to image the disk closer to the star than expected.
