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…

Connecting the Wilson depression to the magnetic field of sunspots

B. Löptien, A. Lagg, M. van Noort +1

Context: In sunspots, the geometric height of continuum optical depth unity is depressed compared to the quiet Sun. This so-called Wilson depression is caused by the Lorentz force…

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…
