WRAY 15-1880 Archives - Astrobiology

Left: Qϕ image of WRAY 15-1880 obtained from the SPHERE polarimetric data. The red dot at the center of the image marks the position of the star; the dashed white circle is the size of the coronagraph used in this observation. The dotted straight lines mark the major and minor axes, as obtained by Curone et al. (2025). Right: similar image, but projected on the disk plane (i “ 39.22 deg) and rotated to have the major axis vertical and the minor axis horizontal. On this plane, the coronagraphic mask is an ellipse represented by the white dashed line. The yellow circle has a radius of 214.1 mas that is the peak of the disk as determined by the ALMA data (see Section 3.3.2). The center of this circle has been offset by 37 mas along the minor axis, to fit the outer contour of the observed disk East of the star, that is the closest side of the disk. The red solid circle (radius of 110 mas) fits the feature seen north of the star. The position of the planet discussed in Section 3.2 at the epoch of the SPHERE polarimetric observation is marked with a small white circle, and its orbit is shown as magenta circle. -- astro-ph.SR

Analysis Of The Young Disk Around WRAY 15-1880: Does It Contain A Primitive Planetary System?

Observations of (giant) planets accreting material within their natal environment are crucial to constrain models for their formation.
