Power spectra of solar brightness variations at different inclinations
N. -E. Nèmec, A. I. Shapiro, N. A. Krivova +4
Magnetic features on the surfaces of cool stars cause variations of their brightness. Such variations have been extensively studied for the Sun. Recent planet-hunting space telesco…
Rotation periods from the inflection point in the power spectrum of stellar brightness variations: II. The Sun
E. M. Amazo-Gómez, A. I. Shapiro, S. K. Solanki +5
Young and active stars generally have regular, almost sinusoidal, patterns of variability attributed to their rotation, while the majority of older and less active stars, including…
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…
Inflection point in the power spectrum of stellar brightness variations. I. The model
A. I. Shapiro, E. M. Amazo-Gómez, N. A. Krivova +1
Context. Considerable effort has been put into using light curves observed by space telescopes such as CoRoT, Kepler and TESS for determining stellar rotation periods. While rotati…
The nature of solar brightness variations
A. I. Shapiro, S. K. Solanki, N. A. Krivova +3
The solar brightness varies on timescales from minutes to decades. Determining the sources of such variations, often referred to as solar noise, is of importance for multiple reaso…
The influence of metallicity on stellar differential rotation and magnetic activity
Christoffer Karoff, Travis S. Metcalfe, Angela R. G. Santos +20
Observations of Sun-like stars over the last half-century have improved our understanding of how magnetic dynamos, like that responsible for the 11-year solar cycle, change with ro…
