Inflection point in the power spectrum of stellar brightness variations III: Faculae vs. Spot dominance on stars with known rotation periods
E. M. Amazo-Gomez, A. I. Shapiro, S. K. Solanki +4
Stellar rotation periods can be determined by observing brightness variations caused by active magnetic regions transiting visible stellar disk as the star rotates. The successful…
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…
Analysis of full disc Ca II K spectroheliograms III. Plage area composite series covering 1892-2019
Theodosios Chatzistergos, Ilaria Ermolli, Natalie A. Krivova +16
We derive the plage area evolution over the last 12 solar cycles employing data from all Ca II K archives available publicly in digital form known to us, including several as yet u…
Effect of metallicity on the detectability of rotational periods in solar-like stars
V. Witzke, T. Reinhold, A. I. Shapiro +2
Accurate determination of stellar rotation periods is important for estimating stellar ages as well as for understanding stellar activity and evolution. While for about thirty thou…
