H- Integral Carrington Synoptic Maps Produced by NSO/NISP

K. J. Shuman, L. Bertello, O. Burtseva +1

Monitoring long-term chromospheric activity and large-scale solar structures like filaments and plages is critical for understanding solar magnetic cycles and predicting space-weat…

Modeling Decadal and Centennial Solar UV Irradiance Changes

Raffaele Reda, Valentina Penza, Serena Criscuoli +5

Reconstructions of solar spectral irradiance - especially in the ultraviolet (UV) range - are crucial for understanding Earth's climate system. Although total solar irradiance (TSI…

Investigating the Temperature Sensitivity of UV Line Ratios in the 280 nm Region of Solar-like Stars

Valentina Penza, Serena Criscuoli, Raffaele Reda +7

Stellar UV spectra are fundamental diagnostics of physical and magnetic properties of stars. For instance, lines like Mg II at 280 nm serve as valuable indicators of stellar activi…

Simulating the Solar Corona with Multiple Solar Photospheric Magnetic Maps during the 8 April 2024 Total Solar Eclipse

Xianyu Liu, Weihao Liu, Ward B. Manchester +11

The 8 April 2024 total solar eclipse (TSE) provides a unique opportunity to study the solar corona. This work presents our simulations of the solar corona at the time of the eclips…

Latitude Quenching Nonlinearity in the Solar Dynamo

Anthony R. Yeates, Luca Bertello, Alexander A. Pevtsov +1

We compare two candidate nonlinearities for regulating the solar cycle within the Babcock-Leighton paradigm: tilt quenching (whereby the tilt of active regions is reduced in strong…

Reconstruction of the Total Solar Irradiance during the last Millenium

Valentina Penza, Luca Bertello, Matteo Cantoresi +5

Solar irradiance variations across various timescales, from minutes to centuries, represents a potential natural driver of past regional and global climate cold phases. To accurate…
