The evolution of exocomets and their source populations
Alexander J. Mustill, Tim Pearce, Michele Bannister +12
We review the current state of knowledge of the long-term evolution of the small bodies that give rise to comets and exocomets, as well as their reservoirs. The active cometary pha…
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…
An observationally based wind model contemporaneous with the radio detections in Boötis
Dag Evensberget, Aline A. Vidotto, Filip Elekes +2
Recent low-frequency array (LOFAR) radio signal detections bearing from the Boötis system have been cautiously attributed to auroral emissions from the hot Jupiter Boötis A…
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…
Spectropolarimetric characterisation of exoplanet host stars in preparation of the Ariel mission. Magnetic environment of HD 63433
S. Bellotti, D. Evensberget, A. A. Vidotto +8
The accurate characterisation of the stellar magnetism of planetary host stars has been gaining momentum, especially in the context of transmission spectroscopy investigations of e…
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…
Polarization of hot Jupiter systems: a likely detection of stellar activity and a possible detection of planetary polarization
Jeremy Bailey, Kimberly Bott, Daniel V. Cotton +6
We present high-precision linear polarization observations of four bright hot Jupiter systems ( Boo, HD 179949, HD 189733 and 51 Peg) and use the data to search for polarized re…
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…
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…
