Magnetic field and chromospheric activity evolution of HD75332: a rapid magnetic cycle in an F star without a hot Jupiter
E. L. Brown, S. C. Marsden, M. W. Mengel +10
Studying cool star magnetic activity gives an important insight into the stellar dynamo and its relationship with stellar properties, as well as allowing us to place the Sun's magn…
MOVES IV. Modelling the influence of stellar XUV-flux, cosmic rays, and stellar energetic particles on the atmospheric composition of the hot Jupiter HD 189733b
Patrick Barth, Christiane Helling, Eva E. Stüeken +7
Hot Jupiters provide valuable natural laboratories for studying potential contributions of high-energy radiation to prebiotic synthesis in the atmospheres of exoplanets. In this fo…
Amplitude Modulation of Short-Timescale Hot Spot Variability
Lauren I. Biddle, Joe Llama, Andrew Collier Cameron +3
Variability of Classical T Tauri Systems (CTTS) occurs over a vast range of timescales. CTTS in particular are subject to variability caused by accretion shocks which can occur sto…
Even More Rapidly Rotating Pre-Main Sequence M Dwarfs with Highly Structured Light Curves: An Initial Survey in the Lower Centaurus-Crux and Upper Centaurus-Lupus Associations
J. R. Stauffer, L. M. Rebull, M. Jardine +6
Using K2, we recently discovered a new type of periodic photometric variability while analysing the light curves of members of Upper Sco (Stauffer \etal\ 2017). The 23 exemplars of…
Identifying solar-like magnetic cycles with Zeeman-Doppler-Imaging (ZDI)
Lisa T. Lehmann, Gaitee A. J. Hussain, Aline A. Vidotto +2
We are reaching the point where spectropolarimetric surveys have run for long enough to reveal solar-like magnetic activity cycles. In this paper we investigate what would be the b…
Magnetic field and prominences of the young, solar-like, ultra-rapid rotator V530 Per
T. -Q. Cang, P. Petit, J. -F. Donati +7
We investigate signatures of magnetic fields and activity at the surface and in the prominence system of the ultra-rapid rotator V530 Per, a G-type solar-like member of the young o…
Measuring stellar magnetic helicity density
K. Lund, M. Jardine, L. T. Lehmann +10
Helicity is a fundamental property of a magnetic field but to date it has only been possible to observe its evolution in one star - the Sun. In this paper we provide a simple techn…
MOVES III. Simultaneous X-ray and ultraviolet observations unveiling the variable environment of the hot Jupiter HD 189733b
V. Bourrier, P. J. Wheatley, A. Lecavelier des Etangs +8
In this third paper of the MOVES (Multiwavelength Observations of an eVaporating Exoplanet and its Star) programme, we combine Hubble Space Telescope far-ultraviolet observations w…
