The HIP 79977 debris disk in polarized light
N. Engler, H. M. Schmid, Ch. Thalmann +40
We present observations of the known edge-on debris disk around HIP 79977 (HD 146897, F star in Upper Sco, 123 pc), taken with the ZIMPOL differential polarimeter of the SPHERE ins…
Constraints on interstellar dust models from extinction and spectro-polarimetry
R. Siebenmorgen, N. V. Voshchinnikov, S. Bagnulo +1
We present polarisation spectra of seven stars in the lines-of-sight towards the Sco OB1 association. Our spectra were obtained within the framework of the Large Interstellar Polar…
SPHERE / ZIMPOL observations of the symbiotic system R Aqr. I. Imaging of the stellar binary and the innermost jet clouds
H. M. Schmid, A. Bazzon, J. Milli +40
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. We have used R Aqr as test t…
Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies
Christian Peest, Peter Camps, Marko Stalevski +2
Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe our implementation of polarization that is…
