Polarimetry toward the Musca Dark Cloud. I. The Catalog
We have used CCD imaging polarimetry to obtain linear polarization measurements of background stars toward the filamentary Musca dark cloud. We present a...
Polarisation and magnetic fields in cool stars and the Sun. A session in memory of Meir Semel
Astrophysical plasmas and magnetic fields are inextricably coupled to each other. But magnetic fields are elusive; they cannot be fully characterized with...
Polarization : Proving ground for methods in radiative transfer.
Polarization of solar lines arises due to illumination of radiating atom by anisotropic (limb darkened/brightened) radiation. Modelling the polarized spectra of...
Polarization Accuracy Verification of the Chromospheric LAyer SpectroPolarimeter
We have developed an advanced UV spectropolarimeter called Chromospheric LAyer SpectroPolarimeter (CLASP2), aimed at achieving very high accuracy measurements (...
Polarization of Photospheric Lines from Turbulent Dynamo Simulations
We employ the magnetic and velocity fields from turbulent dynamo simulations to synthesize the polarization of a typical photospheric line. The synthetic Stokes...
Polynomial Approximants for the Calculation of Polarization Profiles in the He I 10830 Å Multiplet
The He I multiplet at 10830 Å is formed in the incomplete Paschen-Back regime for typical conditions found in solar and stellar atmospheres. The positions and...
PORTA: A three-dimensional multilevel radiative transfer code for modeling the intensity and polarization of spectral lines with massively parallel computers
The interpretation of the intensity and polarization of the spectral line radiation produced in the atmosphere of the Sun and of other stars requires solving a...
Post common envelope binaries from SDSS. VIII. Evidence for disrupted magnetic braking
Context. The standard prescription of angular momentum loss in compact binaries assumes magnetic braking to be very efficient as long as the secondary star has...
Probing deep photospheric layers of the quiet Sun with high magnetic sensitivity
Context. Investigations of the magnetism of the quiet Sun are hindered by extremely weak polarization signals in Fraunhofer spectral lines. Photon noise...
