Block-structured Operator Inference for coupled multiphysics model reduction
Benjamin G. Zastrow, Anirban Chaudhuri, Karen E. Willcox +2
This paper presents a block-structured formulation of Operator Inference as a way to learn structured reduced-order models for multiphysics systems. The approach specifies the gove…
Solar Flare Ion Temperatures
Alexander J. B. Russell, Vanessa Polito, Paola Testa +2
This paper proposes that the ion temperature is several times the local electron temperature in the hot onset phase and at the above-the-loop region of solar flares. The paper cons…
Determining the Magnetic Field in the Atmosphere of a Solar Active Region Observed by the CLASP2.1 Sounding Rocket Experiment
Ryohko Ishikawa, Javier Trujillo Bueno, David E. McKenzie +17
We determine magnetic fields from the photosphere to the upper chromosphere combining data from the Hinode satellite and the CLASP2.1 sounding rocket experiment. CLASP2.1 provided…
X-class flare on Dec 31, 2023, observed by the Solar Ultraviolet Imaging Telescope on board Aditya-L1
Soumya Roy, Durgesh Tripathi, Vishal Upendran +10
We present the multi-wavelength study of the ejection of a plasma blob from the limb flare SOL2023-12-31T21:36:00 from NOAA 13536 observed by the Solar Ultraviolet Imaging Telescop…
Orbit, meteoroid size, and cosmic ray exposure history of the Aguas Zarcas CM2 breccia
Peter Jenniskens, Gerardo J. Soto, Gabriel Goncalves Silva +21
The Aguas Zarcas (Costa Rica) CM2 carbonaceous chondrite fell during night time in April 2019. Security and dashboard camera video of the meteor were analyzed to provide a trajecto…
Coronal energy release by MHD avalanches III. Identification of a reconnection outflow from a nanoflare
G. Cozzo, P. Pagano, F. Reale +5
Outflows perpendicular to the guide field are believed to be a possible signature of magnetic reconnection in the solar corona and specifically a way to detect the occurrence of ub…
