Fast and periodic propagating disturbances along coronal loops detected with EUI on board Solar Orbiter
A. Dolliou, S. Mandal, K. Barczynski +9
Recent high-resolution observations from the Solar Orbiter mission can help detect the indirect signatures of heating at the smallest scales. In this work we measure the properties…
White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics
E. Pariat, Q. Noraz, B. Perri +61
The project of the European Solar Telescope aims to provide a state-of-the art infrastructure to study the Sun and its interactions with Earth and the heliosphere. This 4.2m apertu…
A Point-Spread Function for the Extreme Ultraviolet High-Resolution Imager on board Solar Orbiter
Stefan J. Hofmeister, Emil Kraaikamp, Sergei Shestov +7
We present the point-spread function (PSF) of the Extreme Ultraviolet High-Resolution Imager (HRIEUV) onboard Solar Orbiter, which observes the Sun at 174 Angstrom. This PSF provid…
Probing Solar Polar Regions
Yuanyong Deng, Hui Tian, Jie Jiang +45
The magnetic fields and dynamical processes in the solar polar regions play a crucial role in the solar magnetic cycle and in supplying mass and energy to the fast solar wind, ulti…
Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
28 Years of Sun-as-a-star Extreme Ultraviolet Light Curves from SOHO EIT
Emily Sandford, Frédéric Auchère, Annelies Mortier +2
The Solar and Heliospheric Observatory (SOHO) Extreme-ultraviolet Imaging Telescope (EIT) has been taking images of the Solar disk and corona in four narrow EUV bandpasses (171Ã ,…
