Polarimetry of the binary PDS 144
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Aims. Our goal is to study the circumstellar environment associated with each component of the wide intermediate-mass pre-main sequence binary system PDS 144 using broadband polarimetry. Methods. We present near-infrared ...
Measuring the continuum polarization with ESPaDOnS
(European Southern Observatory, 2015)
Aims. Our goal is to test the feasibility of obtaining accurate measurements of the continuum polarization from high-resolution spectra using the spectropolarimetric mode of ESPaDOnS. Methods. We used the new pipeline OPERA ...
Discovery of a complex linearly polarized spectrum of Betelgeuse dominated by depolarization of the continuum
(EDP Sciences, 2016)
Context. Betelgeuse is an M supergiant that harbors spots and giant granules at its surface and presents linear polarization of its continuum.
Aims. We have previously discovered linear polarization signatures associated ...
Optical Polarization of solar type stars with debris disks
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2015-04)
We report optical aperture polarimetry for 34 southern hemisphere mainsequence stars with debris disks, in addition to 54 stars without evidence of disk. These sets of stars are combined with another set of 109 stars from ...
