Activity correlation and temporal variation of small-scale magnetic fields on young Sun-like stars
A. Hahlin, B. Zaire, C. P. Folsom +2
We aim to evaluate how well the variation of small-scale magnetic fields on the stellar surface can be monitored with time-series observations. Further, we aim to establish to what…
Comparative study of small-scale magnetic fields on Boo A using optical and near-infrared spectroscopy
A. Hahlin, O. Kochukhov, P. Chaturvedi +12
Magnetic field investigations of Sun-like stars, using Zeeman splitting of non-polarised spectra, in the optical and H-band have found significantly different magnetic field streng…
A conclusive non-detection of magnetic field in the Am star o Peg with high-precision near-infrared spectroscopy
O. Kochukhov, A. M. Amarsi, A. Lavail +10
The A-type metallic-line (Am) stars are typically considered to be non-magnetic or possessing very weak sub-G magnetic fields. This view has been repeatedly challenged in the liter…
Accretion and magnetism on young eccentric binaries: DQ Tau and AK Sco
Kim Pouilly, Axel Hahlin, Oleg Kochukhov +2
The accretion and ejection of mass in pre-main sequence (PMS) stars are key processes in stellar evolution as they shape the stellar angular momentum transport necessary for the st…
Multi-scale magnetic field investigation of the M-dwarf eclipsing binary CU Cancri
A. Hahlin, O. Kochukhov, A. D. Rains +4
We aim to characterise the magnetic field of the eclipsing binary CU Cnc. The determination of magnetic field parameters of this target enables comparisons with both observations o…
Determination of small-scale magnetic fields on Sun-like stars in the near-infrared using CRIRES
A. Hahlin, O. Kochukhov, A. D. Rains +18
We aim to characterise the small-scale magnetic fields for a sample of 16 Sun-like stars and investigate the capabilities of the newly upgraded near-infrared (NIR) instrument CRIRE…
Accretion process, magnetic fields, and apsidal motion in the pre-main sequence binary DQ Tau
Kim Pouilly, Oleg Kochukhov, Ágnes Kóspál +3
Classical T Tauri stars (CTTSs) are young stellar objects that accrete materials from their accretion disc influenced by their strong magnetic field. The magnetic pressure truncate…
