Multiwavelength Mitigation of Stellar Activity in Astrometric Planet Detection
Avi Kaplan-Lipkin, Bruce Macintosh, Alexander Madurowicz +4
Astrometry has long been a promising technique for exoplanet detection. At the theoretical limits, astrometry would allow for the detection of smaller planets than previously seen…
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…
MPS-ATLAS: A fast all-in-one code for synthesising stellar spectra
V. Witzke, A. I. Shapiro, M. Cernetic +6
Context. Stellar spectral synthesis is essential for various applications, ranging from determining stellar parameters to comprehensive stellar variability calculations. New observ…
Radiative transfer with opacity distribution functions: Application to narrow band filters
L. S. Anusha, A. I. Shapiro, V. Witzke +3
Modelling of stellar radiative intensities in various spectral pass-bands plays an important role in stellar physics. At the same time the direct calculations of the high-resolutio…
Forward modelling of Kepler-band variability due to faculae and spots
Luke J. Johnson, Charlotte N. Norris, Yvonne C. Unruh +4
Variability observed in photometric lightcurves of late-type stars (on timescales longer than a day) is a dominant noise source in exoplanet surveys and results predominantly from…
The Dimmest State of the Sun
K. L. Yeo, S. K. Solanki, N. A. Krivova +5
How the solar electromagnetic energy entering the Earth's atmosphere varied since pre-industrial times is an important consideration in the climate change debate. Detrimental to th…
