VPNEP: Detailed characterization of TESS targets around the Northern Ecliptic Pole
K. G. Strassmeier, M. Weber, D. Gruner +13
We embarked on a high-resolution optical spectroscopic survey of bright Transiting Exoplanet Survey Satellite (TESS) stars around the Northern Ecliptic Pole (NEP), dubbed the Vatic…
Inference of magnetic fields in the very quiet Sun
M. J. Mart\' inez González, A. Pastor Yabar, A. Lagg +29
We present high-precision spectro-polarimetric data with high spatial resolution (0.4) of the very quiet Sun at 1.56m obtained with the GREGOR telescope to shed some light o…
Signatures of the impact of flare ejected plasma on the photosphere of a sunspot light-bridge
T. Felipe, M. Collados, E. Khomenko +4
We investigate the properties of a sunspot light-bridge, focusing on the changes produced by the impact of a plasma blob ejected from a C-class flare. We observed a sunspot in acti…
Penumbral thermal structure below the visible surface
J. M. Borrero, M. Franz, R. Schlichenmaier +2
. The thermal structure of the penumbra below its visible surface (i.e., ) has important implications for our present understanding of sunspots and their penumb…
Three-dimensional structure of a sunspot light bridge
T. Felipe, M. Collados, E. Khomenko +26
Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar physics. Light bridges are commonl…
Upper Chromospheric Magnetic Field of a Sunspot Penumbra: Observations of Fine Structure
J. Joshi, A. Lagg, S. K. Solanki +22
The fine-structure of magnetic field of a sunspot penumbra in the upper chromosphere is to be explored and compared to that in the photosphere. High spatial resolution spectropolar…
