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…

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…

Multi-wavelength, spatially resolved modelling of HD 48682's debris disc

S. Hengst, J. P. Marshall, J. Horner +1

Asteroids and comets (planetesimals) are created in gas- and dust-rich protoplanetary discs. The presence of these planetesimals around main-sequence stars is usually inferred from…

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…

TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star

Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91

We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
