A comparative study of two X2.2 and X9.3 solar flares observed with HARPS-N: Reconciling Sun-as-a-star spectroscopy and high-spatial resolution solar observations in the context of the solar-stellar connection
A. G. M. Pietrow, M. Cretignier, M. K. Druett +14
Stellar flares cannot be spatially resolved, which complicates ascertaining the physical processes behind particular spectral signatures. Due to their proximity to Earth, solar fla…
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…
The Sun is less active than other solar-like stars
Timo Reinhold, Alexander I. Shapiro, Sami K. Solanki +4
Magnetic activity of the Sun and other stars causes their brightness to vary. We investigate how typical the Sun's variability is compared to other solar-like stars, i.e. those wit…
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…
