Predictions of astrometric jitter for Sun-like stars. I. The model and its application to the Sun as seen from the ecliptic
Alexander I. Shapiro, Sami K. Solanki, Natalie A. Krivova
The advent of Gaia, capable of measuring stellar wobbles caused by orbiting planets, raised an interest to the astrometric detection of exoplanets. Another source of such wobbles (…
Amplification of brightness variability by active-region nesting in solar-like stars
Emre Işık, Alexander I. Shapiro, Sami K. Solanki +1
Kepler observations revealed that hundreds of stars with near-solar fundamental parameters and rotation periods have much stronger and more regular brightness variations than the S…
Reply to the comment of T. Metcalfe and J. van Saders on the Science report "The Sun is less active than other solar-like stars"
T. Reinhold, A. I. Shapiro, S. K. Solanki +4
This is our reply to the comment of T. Metcalfe and J. van Saders on the Science report "The Sun is less active than other solar-like stars" by T. Reinhold, A. I. Shapiro, S. K. So…
Solar-type Stars Observed by LAMOST and Kepler
Jinghua Zhang, Alexander I. Shapiro, Shaolan Bi +8
Obtaining measurements of chromospheric and photometric activity of stars with near-solar fundamental parameters and rotation periods is important for a better understanding of sol…
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…
Connecting measurements of solar and stellar brightness variations
N. -E. Nèmec, E. Işık, A. I. Shapiro +3
Comparing solar and stellar brightness variations is hampered by the difference in spectral passbands used in observations as well as by the possible difference in the inclination…
