Stokes inversion based on convolutional neural networks
Context. Spectropolarimetric inversions are routinely used in the field of solar physics for the extraction of physical information from observations. The...
Strategy for the Inversion of Hinode Spectropolarimetric Measurements in the Quiet Sun
In this paper we propose an inversion strategy for the analysis of spectropolarimetric measurements taken by Hinode in the quiet Sun. The Spectro-Polarimeter of...
Structure and Dynamics of the Sun's Interior Revealed by the Helioseismic and Magnetic Imager
High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) provide a unique three...
Structure of Plage Flux Tubes from the Inversion of Stokes Spectra. I. Spatially Averaged Stokes I and V Profiles
We present results of the inversion of spatially averaged Stokes I and V profiles emerging from plage regions near disk center. The observations analyzed in...
Studying the accretion geometry of EXO 2030+375 at luminosities close to the propeller regime
The Be X-ray binary EXO 2030+375was in an extended low-luminosity state during most of 2016. We observed this state with NuSTARand Swift, supported by...
Submillimeter Polarization Spectrum in the Vela C Molecular Cloud
Polarization maps of the Vela C molecular cloud were obtained at 250, 350, and 500 μm during the 2012 flight of the balloon-borne telescope BLASTPol. These...
Submillimeter Polarization Spectrum of the Carina Nebula
Linear polarization maps of the Carina Nebula were obtained at 250, 350, and 500 μm during the 2012 flight of the Balloon-borne Large Aperture Submillimeter...
SUNRISE III: Overview of Observatory and Instruments
In July 2024, SUNRISE completed its third successful science flight. The SUNRISE III observatory had been upgraded significantly after the two previous...
Sunspot seismic halos generated by fast MHD wave refraction
Aims: We suggest an explanation for the high-frequency power excess surrounding active regions known as seismic halos. Methods: We use numerical simulations of...
