The total K-band polarised intensity map of MWC 758 (left, Ren et al. 2023) compared to the total intensity at 2.2 µm from our Radmc3d model (right). Both are masked
The WISPIT 2 system as seen by the Magellan Telescope in Chile and the Large Binocular Telescope in Arizona. The protoplanet WISPIT 2b appears as a purple dot in a
Transit light curves and fits for HD 60779 b. The transit models were all fit simultaneously with the RVs, details listed in Table 2. The upper left panel shows the
Absorption spectrum corresponding roughly to the surface Earth gas mixture (N2, H2O and CO2). Here we assume 1 bar of total pressure, including 370 ppm of CO2 and 0.01 bar
