A Revisit to the Optical Starlight Polarization Catalogue by Heiles: Distance Update
Chinese Astronomy and Astrophysics, 2021Abstract Starlight polarization serves one of the powerful tools to study magnetic fields in the Galactic interstellar medium. Heiles catalogue contains polarization information for 9286 stars, and is by far the biggest. This catalogue has been extensively used to study the magnetic fields.

Study of variations in starlight polarization
Vistas in Astronomy, 1968The problem of starlight polarization is still far from being solved, and one cannot yet discern any obvious approach to a final solution. One sign of this is the increasing uncerta inty concerning the location of the starlight polarization-mechanism.

Polarization Of Starlight By Interstellar Dust
1996This paper reviews observations of interstellar linear polarization over the spectral range 0.12-12 μm and discusses their implications for models of interstellar extinction and grain alignment. The wavelength dependence of polarization in the visible is well described by the empirical Serkowski formula p(λ)/P max = exp[-Kln2(λmax/λ)], where λmax is ...

The polarization of starlight in NGC 654 and IC 5146
Astrophysics and Space Science, 1976Two very young star clusters, NGC 654 and IC 5146 are studied using photographic polarization measures with limiting magnitudeB=15m,with a view to determining the nature of magnetic fields in the vicinities of these clusters. Starlight from NGC 654 is found to be polarized in a direction parallel to the galactic plane, the fainter members being more ...

Measurements of the polarization of starlight
2019527 stars in h and chi Persei to V = 13 have been measured. Using the Stokes parameters, comparison with published photoelectric measures for 54 stars gives an r.m.s. deviation of ± Om.029 per star, and the photoelectric and photographic means agree to within Om.003 and 1 degree.

Traces of exomoons in flux and polarization signals of starlight reflected by exoplanets
2017The detection of moons around extrasolar planets is one of the main focuses of current and future observatories. These silent companions contribute to the planets' observed signals but are barely detectable with current methods. Numerous gaseous exoplanets are known to orbit in the habitable zones of stars, and the expected abundance of natural ...
