The first out-of-ecliptic observations of the polar magnetic field of the Sun

D. Calchetti, S. K. Solanki, J. Hirzberger +25

Direct remote-sensing observations of the solar poles have been hindered by the restricted view obtained from the ecliptic plane. For the first time ever, Solar Orbiter with its re…

Les Trente Glorieuses: 29 years of helioseismic observations with the Luminosity Oscillations Imager

Thierry Appourchaux

The Luminosity Oscillations Imager (LOI) of the Variability of Solar Irradiance and Gravity Oscillations (VIRGO) instrument aboard the SoHO mission has been operating for almost th…

Supergranulation and Poleward Migration of the Magnetic Field at High Latitudes of the Sun

L. P. Chitta, D. Calchetti, J. Hirzberger +26

Magnetoconvection at the solar surface governs the dynamics in the upper solar atmosphere and sustains the heliosphere. Properties of this fundamental process are poorly described…

Sausage, kink, and fluting MHD wave modes identified in solar magnetic pores by Solar Orbiter/PHI

S. Jafarzadeh, L. A. C. Schiavo, V. Fedun +25

Solar pores are intense concentrations of magnetic flux that emerge through the Sun's photosphere. When compared to sunspots, they are much smaller in diameter and hence can be imp…

Reconstruction of total solar irradiance variability as simultaneously apparent from Solar Orbiter and Solar Dynamics Observatory

K. L. Yeo, N. A. Krivova, S. K. Solanki +42

Solar irradiance variability has been monitored almost exclusively from the Earth's perspective. {We present a method to combine the unprecedented observations of the photospheric…

Coronal voids and their magnetic nature

J. D. Nölke, S. K. Solanki, J. Hirzberger +68

Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these…

Intensity contrast of solar network and faculae close to the solar limb, observed from two vantage points

K. Albert, N. A. Krivova, J. Hirzberger +43

The brightness of faculae and network depends on the angle at which they are observed and the magnetic flux density. Close to the limb, assessment of this relationship has until no…

Accuracy analysis of the on-board data reduction pipeline for the Polarimetric and Helioseismic Imager on the Solar Orbiter mission

Kinga Albert, Johann Hirzberger, J. Sebastián Castellanos Durán +4

Scientific data reduction on-board deep space missions is a powerful approach to maximise science return, in the absence of wide telemetry bandwidths. The Polarimetric and Heliosei…

Magnetic fields inferred by Solar Orbiter: A comparison between SO/PHI-HRT and SDO/HMI

J. Sinjan, D. Calchetti, J. Hirzberger +31

The High Resolution Telescope (HRT) of the Polarimetric and Helioseismic Imager on board the Solar Orbiter spacecraft (SO/PHI) and the Helioseismic and Magnetic Imager (HMI) on boa…
