Faculae cancel out on the surfaces of active Suns
N. -E. Nèmec, A. I. Shapiro, E. Işık +5
Surfaces of the Sun and other cool stars are filled with magnetic fields, which are either seen as dark compact spots or more diffuse bright structures like faculae. Both hamper de…
Predictions of Astrometric Jitter for Sun-like Stars. III. Fast Rotators
K. Sowmya, N. -E. Nèmec, A. I. Shapiro +3
A breakthrough in exoplanet detections is foreseen with the unprecedented astrometric measurement capabilities offered by instrumentation aboard Gaia space observatory. Besides, as…
Predictions of Astrometric Jitter for Sun-like Stars. II. Dependence on Inclination, Metallicity, and Active-Region Nesting
K. Sowmya, N. -E. Nèmec, A. I. Shapiro +5
Ultra-precise astrometry from the Gaia mission is expected to lead to astrometric detections of more than 20,000 exoplanets in our Galaxy. One of the factors that could hamper such…
Where have all the solar-like stars gone? Rotation period detectability at various inclinations and metallicities
Timo Reinhold, Alexander I. Shapiro, Veronika Witzke +3
The plethora of photometric data collected by the Kepler space telescope has promoted the detection of tens of thousands of stellar rotation periods. However, these periods are not…
Observing and modelling the young solar analogue EK Draconis: starspot distribution, elemental abundances, and evolutionary status
H. V. Şenavcı, T. Kılıçoğlu, E. Işık +4
Observations and modelling of stars with near-solar masses in their early phases of evolution is critical for a better understanding of how dynamos of solar-type stars evolve. We e…
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…
