GTC 8-13um spectropolarimetry toward CygOB2-12
Listed in IVOA Registry (Virtual Observatory)
We present the first mid-IR detection of the linear polarization toward the star CygOB2-12, a luminous blue hypergiant that, with A_V_~10mag of foreground extinction, is a benchmark in the study of the properties of dust in the diffuse interstellar medium.
Description
The 8-13{mu}m spectropolarimetry, obtained with the CanariCam multimode camera at the Gran Telescopio CANARIAS shows clear trends with wavelength characteristic of silicate grains aligned in the interstellar magnetic field.
The maximum polarization, detected with 7.8{sigma} statistical significance near 10.2{mu}m, is (1.24+/-0.28)% with position angle 126{deg}+/-8{deg}. We comment on these measurements in the context of recent models for the dust composition in the diffuse interstellar medium.
