Investigating Solar Wind Outflows from Open-Closed Magnetic Field Structures Using Coordinated Solar Orbiter and Hinode Observations
Nawin Ngampoopun, Roberto Susino, David H. Brooks +13
ESA/NASA's Solar Orbiter (SO) allows us to study the solar corona at closer distances and from different perspectives, which helps us to gain significant insights into the origins…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes II. Evidence for coronal emission
M. Marongiu, A. Pellizzoni, S. Righini +43
One of the most important objectives of solar physics is the physical understanding of the solar atmosphere, the structure of which is also described in terms of the density (N) an…
Coronal Heating Rate in the Slow Solar Wind
Daniele Telloni, Marco Romoli, Marco Velli +59
This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations…
Does Turbulence along the Coronal Current Sheet Drive Ion Cyclotron Waves?
Daniele Telloni, Gary P. Zank, Laxman Adhikari +32
Evidence for the presence of ion cyclotron waves, driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the jo…
Connecting Solar Orbiter remote-sensing observations and Parker Solar Probe in-situ measurements with a numerical MHD reconstruction of the Parker spiral
Ruggero Biondo, Alessandro Bemporad, Paolo Pagano +21
As a key feature, NASA's Parker Solar Probe (PSP) and ESA-NASA's Solar Orbiter (SO) missions cooperate to trace solar wind and transients from their sources on the Sun to the inner…
Observation of Magnetic Switchback in the Solar Corona
Daniele Telloni, Gary P. Zank, Marco Stangalini +49
Switchbacks are sudden, large radial deflections of the solar wind magnetic field, widely revealed in interplanetary space by the Parker Solar Probe. The switchbacks' formation mec…
Exploring the Solar Wind from its Source on the Corona into the Inner Heliosphere during the First Solar Orbiter - Parker Solar Probe Quadrature
Daniele Telloni, Vincenzo Andretta, Ester Antonucci +68
This Letter addresses the first Solar Orbiter (SO) -- Parker Solar Probe (PSP) quadrature, occurring on January 18, 2021, to investigate the evolution of solar wind from the extend…
Ego4D: Around the World in 3,000 Hours of Egocentric Video
Kristen Grauman, Andrew Westbury, Eugene Byrne +82
We introduce Ego4D, a massive-scale egocentric video dataset and benchmark suite. It offers 3,670 hours of daily-life activity video spanning hundreds of scenarios (household, outd…
Effects of the chromospheric Lyα line profile shape on the determination of the solar wind HI outflow velocity using the Doppler dimming technique
G. E. Capuano, S. Dolei, D. Spadaro +15
The determination of solar wind outflow velocity is fundamental in order to probe the mechanisms of wind acceleration in the corona. We aim to study, via the Doppler dimming techni…
First light observations of the solar wind in the outer corona with the Metis coronagraph
M. Romoli, E. Antonucci, V. Andretta +65
The investigation of the wind in the solar corona initiated with the observations of the resonantly scattered UV emission of the coronal plasma obtained with UVCS-SOHO, designed to…
Progress on the Astrometric Gravitation Probe design
Mario Gai, Alberto Vecchiato, Alberto Riva +13
The Astrometric Gravitation Probe mission is a modern version of the 1919 Dyson-Eddington-Davidson experiment, based on a space-borne telescope with a permanent built-in eclipse, p…
The ASTRA project: a doorway to future astrometry
Mario Gai, Zhaoxiang Qi, Mario G. Lattanzi +15
Astrometric Science and Technology Roadmap for Astrophysics (ASTRA) is a bilateral cooperation between China and Italy with the goal of consolidating astrometric measurement concep…
RAFTER: Ring Astrometric Field Telescope for Exo-planets and Relativity
Alberto Riva, Mario Gai, Alberto Vecchiato +5
High precision astrometry aims at source position determination to a very small fraction of the diffraction image size, in high SNR regime. One of the key limitations to such goal…
