R Aqr SPHERE/ZIMPOL narrow-Hα image
(2017)R Aqr is a symbiotic binary system consisting of a mira variable, a hot companion with a spectacular jet outflow, and an extended emission line nebula. Because of its proximity to the Sun, this object has been studied in much detail with many types of high resolution imaging and interferometric techniques. We have used R Aqr as test target for the visual camera subsystem ZIMPOL, which is part of the new extreme adaptive optics (AO) ...Data Collection -
HD 117214 debris disk polarization images
(2020)Young stars with debris disks are the most promising targets for an exoplanet search because debris indicate a successful formation of planetary bodies. Debris disks can be shaped by planets into ring structures that give valuable indications on the presence and location of planets in the disk. We performed observations of the Sco-Cen F star HD 117214 to search for planetary companions and to characterize the debris disk structure. HD ...Data Collection -
RX J1604.3-213010 SPHERE polarimetric images: J/A+A/676/A6
(2023)The presented SPHERE/ZIMPOL images of RX J1604.3-213010 were taken with R_PRIM + dichroic filters and the SPHERE/IRDIS images were taken with J-band and H-band filter, respectively. The images show the averaged Qφ and I{star} for all three wavelengths. The averaged images for Qφ and I{star} for R, J, and H band as presented in Figure 1. Images are cut to 3*3 arcsec size.Data Collection
