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…
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…
