Searching for optical pulsations from spider millisecond pulsars with the fast photometer SiFAP2
Christian Malacaria, Alessandro Papitto, Filippo Ambrosino +19
Optical pulsations from millisecond pulsars (MSPs) have recently been detected in a transitional MSP and an accreting MSP. Evidence for optical pulsations has also been found for a…
PRICM3: A novel Polarization Ratio framework for three-dimensional CME reconstruction
Yara De Leo, Manuela Temmer, Fernando M. López +15
Coronal mass ejections (CMEs) are inherently three-dimensional (3D), but traditional white-light coronagraphs provide only two-dimensional (2D) projections. While the Polarization…
A view of the evolution of a CME and the associated wave-trains at high spatial and temporal resolution

Context. Studying the kinematic and dynamic evolution of fast eruptive events from the middle to high solar corona is a primary objective of the Metis coronagraph on Solar Orbiter.…
Evolution of the transitional millisecond pulsar PSR J1023+0038 from Aqueye+ and NICER observations
Silvia Conforti, Luca Zampieri, Michele Fiori +3
Transitional millisecond pulsars (tMSPs) are old neutron stars spun up by accretion from a low-mass companion. These objects can switch between two emission regimes: rotation-power…
First detection of acoustic-like flux in the middle solar corona
V. Andretta, L. Abbo, G. Jerse +28
Waves are thought to play a significant role in the heating of the solar atmosphere and the acceleration of the wind. Among the many types of waves observed in the Sun, the so-call…

We report the results of a comprehensive analysis of the multiwavelength (in optical and X-rays) and multitimescale (from months to tenths of a second) variability of the 2018-2020…
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…
Metis Observations of Alfvénic Outflows Driven by Interchange Reconnection in a Pseudostreamer
P. Romano, P. Wyper, V. Andretta +33
This study presents observations of a large pseudostreamer solar eruption and, in particular, the post-eruption relaxation phase, as captured by Metis onboard the Solar Orbiter on…
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…
Eruptive events with exceptionally bright emission in HI Ly-alpha observed by the Metis coronagraph
G. Russano, V. Andretta, Y. De Leo +29
Metis, the coronagraph on board Solar Orbiter, provides for the first time coronagraphic imaging in the ultraviolet HI Ly-alpha line and, simultaneously, in polarized visible light…
Prospects for a survey of the Galactic plane with the Cherenkov Telescope Array
CTA Consortium
Approximately one hundred sources of very-high-energy (VHE) gamma rays are known in the Milky Way. A survey of the entire Galactic Plane in the energy range from a few tens of GeV…
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…
Simultaneous and panchromatic observations of the Fast Radio Burst FRB 20180916B
