21. 3-Dimensional reconstruction of the thermal X-ray emission in solar flares

Palumbo, Barbara (Università di Genova)

Since October 2022, for the first time, two indirect X-ray imagers, the Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter and the Hard X-ray Imager (HXI) on board the Chinese ASO-S mission, are simultaneously observing the Sun in the hard X-ray regime. Given that the two telescopes have different vantage points on the star, it is possible to combine their stereoscopic...

20. Can we extract F-corona from Metis data?

Prof. Romoli, Marco (Università di Firenze)

The photospheric radiation scattered by dust particles in the vicinity of the Sun is known as the F-corona. The brightness of the F-corona dominates over the K-corona at distances greater than approximately 3 solar radii. For coronagraphs orbiting in the ecliptic plane at similar distances from the Sun, such as Stereo/Secchi and SOHO/LASCO, deriving the F-corona is relatively straightforward...

19. Compact downflows in open-field regions observed by Metis during the fourth Solar Orbiter perihelion

Andretta, Vincenzo (Istituto Nazionale di Astrofisica (INAF))

The fourth perihelion of the Solar Orbiter nominal mission occurred on October 7h, 2023. During the 12-days window around the closest approach (0.29 au), Metis carried out a series of observations at medium and high cadence: from 120 s in pB sequences, down to 20 s in total brightness runs. During the high-cadence observations carried out on October 5th 2023, Metis captured numerous features...
