Re-evaluating solar irradiance reconstructions: No evidence for large secular trends
Theodosios Chatzistergos, Natalie A. Krivova, Mathew J. Owens +1
The authors reassess solar irradiance reconstructions that previously suggested large secular increases and find that, after correcting the linking of cosmogenic isotope and neutro…
Quantifying the effect of passband on observations in the Ca II K line
Ajay Kumar Yadav, Theodosios Chatzistergos, Natalie Krivova +33
Full-disk observations of the Sun in the Ca II K line have been carried out since the late 19th century at various observatories worldwide. These long-term records of solar activit…
Solar Irradiance Reconstruction over the Telescopic Era Using a Revised Photospheric Magnetic Field Model
D. Temaj, N. A. Krivova, T. Chatzistergos +2
The Sun is the primary source of energy for Earth and one of the main external drivers of its climate. Solar irradiance -- the radiative power emitted by the Sun and received at 1-…
Structure and Dynamics of the Sun's Interior Revealed by Helioseismic and Magnetic Imager
Alexander Kosovichev, Sarbani Basu, Yuto Bekki +43
High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the…
Revisiting the SATIRE-S irradiance reconstruction: Heritage of Mt Wilson magnetograms and Ca II K observations
Theodosios Chatzistergos, Natalie A. Krivova, Sami K. Solanki +1
Accurate information on long-term variations in solar irradiance, important for understanding the solar influence on Earth's climate, cannot be derived from direct irradiance measu…
Detectability of Solar Rotation Period Across Various Wavelengths
Valeriy Vasilyev, Timo Reinhold, Alexander I. Shapiro +3
The light curves of old G-dwarfs obtained in the visible and near-infrared wavelength ranges are highly irregular. This significantly complicates the detectability of the rotation…
