Zeeman Doppler Imaging of ksi Boo A and B
K. G. Strassmeier, T. A. Carroll, I. V. Ilyin
We present a magnetic-field surface map for both stellar components of the young visual binary ksi Boo AB (A: G8V, B: K5V). Employed are high resolution Stokes-V spectra obtained w…
A rotational age for the open cluster NGC 2281
D. J. Fritzewski, S. A. Barnes, J. Weingrill +3
Cool star rotation periods have become an important tool in determining ages of open clusters. We aim to estimate the age of the open cluster NGC 2281 based on the rotational prope…
Constraints on Magnetic Braking from the G8 Dwarf Stars 61 UMa and Cet
Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11
During the first half of their main-sequence lifetimes, stars rapidly lose angular momentum to their magnetized winds, a process known as magnetic braking. Recent observations sugg…
The PEPSI Exoplanet Transit Survey. III: The detection of FeI, CrI and TiI in the atmosphere of MASCARA-1 b through high-resolution emission spectroscopy
G. Scandariato, F. Borsa, A. S. Bonomo +19
Hot giant planets like MASCARA-1 b are expected to have thermally inverted atmospheres, that makes them perfect laboratory for the atmospheric characterization through high-resolut…
Io's Optical Aurorae in Jupiter's Shadow
Carl Schmidt, Mikhail Sharov, Katherine de Kleer +13
Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io's atmosphere. Recent studies have established that the majority of Io…
Measuring the variability of directly imaged exoplanets using vector Apodizing Phase Plates combined with ground-based differential spectrophotometry
Ben J. Sutlieff, Jayne L. Birkby, Jordan M. Stone +11
Clouds and other features in exoplanet and brown dwarf atmospheres cause variations in brightness as they rotate in and out of view. Ground-based instruments reach the high contras…
