Eating planets makes you younger: The magnetic dynamo rejuvenation of GJ 504 by planetary engulfment
S. Bellotti, C. Pezzotti, G. Buldgen +3
With the discovery of a few thousand exoplanets, questions have been raised regarding star-planet interactions and whether the presence of a companion may affect stellar properties…
The attempted polarity reversal and evolving magnetic environment of AD Leo
K. G. Smith, D. Evensberget, S. Bellotti +3
In the past two decades, the observed large-scale magnetic field of the active M dwarf star AD Leo has evolved from strongly to mildly negative, raising a suspicion that it might s…
Spectropolarimetric characterisation of exoplanet host stars in preparation of the mission II. The magnetised wind environment of TOI-1860, DS Tuc A, and HD 63433
S. Bellotti, A. Lavail, D. Evensberget +10
We update the status of the spectropolarimetric campaign dedicated to characterise the magnetic field properties of a sample of known exoplanet-hosting stars included in the curren…
Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14
Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bot…
High-latitude coronal mass ejections on the young solar-like star AB Dor
K. Markus Strickert, Dag Evensberget, Aline A. Vidotto
AB Dor is a young solar-type star with a surface large-scale magnetic field to times stronger than the that of the Sun. Although strong magnetic fields are thought to…
Rotational evolution of young-to-old stars with data-driven three-dimensional wind models
D. Evensberget, A. A. Vidotto
Solar-type stars form with a wide range of rotation rates. A wide range persists until a stellar age of 0.6 Gyr, after which solar-type stars exhibit Skumanich spin-down. Rotationa…
The winds of young Solar-type stars in the Pleiades, AB Doradus, Columba and Pictoris
Dag Evensberget, Stephen C. Marsden, Bradley D. Carter +6
Solar-type stars, which shed angular momentum via magnetised stellar winds, enter the main sequence with a wide range of rotational periods . This initially wide rang…
The Rotationally Modulated Polarization of Boo A
Daniel V. Cotton, Dag Evensberget, Stephen C. Marsden +9
We have observed the active star Boo A (HD 131156A) with high precision broadband linear polarimetry contemporaneously with circular spectropolarimetry. We find both signals ar…
