The relationship between bipolar magnetic regions and their sunspots
K. L. Yeo, S. K. Solanki, N. A. Krivova +1
The relationship between bipolar magnetic regions (BMRs) and their sunspots is an important property of the solar magnetic field, but it is not well constrained. One consequence is…
Modeling stellar Ca II H & K emission variations. I. Effect of inclination on the S-index
K. Sowmya, A. I. Shapiro, V. Witzke +5
The emission in the near ultraviolet Ca II H & K lines is modulated by stellar magnetic activity. Although this emission, quantified via the S-index, has been serving as a prime pr…
Intensity contrast of solar network and faculae -- II. Implications for solar irradiance modelling
K. L. Yeo, N. A. Krivova
We aim to gain insight into the effect of network and faculae on solar irradiance from their apparent intensity. Taking full-disc observations from the Solar Dynamics Observatory,…
The Dimmest State of the Sun
K. L. Yeo, S. K. Solanki, N. A. Krivova +5
How the solar electromagnetic energy entering the Earth's atmosphere varied since pre-industrial times is an important consideration in the climate change debate. Detrimental to th…
How faculae and network relate to sunspots, and the implications for solar and stellar brightness variations
K. L. Yeo, S. K. Solanki, N. A. Krivova
How global faculae and network coverage relates to that of sunspots is relevant to the brightness variations of the Sun and Sun-like stars. We extend earlier studies that found the…
Readdressing the UV solar variability with SATIRE-S: non-LTE effects
R. V. Tagirov, A. I. Shapiro, N. A. Krivova +3
Context. Solar spectral irradiance (SSI) variability is one of the key inputs to models of the Earth's climate. Understanding solar irradiance fluctuations also helps to place the…
