Far beyond the Sun: III. The magnetic cycle of Horologii
Julián D. Alvarado-Gómez, Gaitee A. J. Hussain, Eliana M. Amazo-Gómez +6
We present a comprehensive investigation of the magnetic cycle of the young, active solar analogue Horologii ( Hor) based on intensive spectropolarimetric monitoring using H…
Short- and long-term variations of the high mass accretion rate classical T Tauri star DR Tau
Gabriella Zsidi, Ágnes Kóspál, Péter Ábrahám +20
Classical T Tauri stars are newly formed, low mass stars which may display both periodic and random variations in their brightness. The interaction between the star and its circums…
First Chromospheric Activity and Doppler Imaging Study of PW And Using a New Doppler Imaging Code: SpotDIPy
Engin Bahar, Hakan V. Şenavcı, Emre Işık +4
Measuring coverage of dark spots on cool stars is important in understanding how stellar magnetic activity scales with the rotation rate and convection zone depth. In this respect,…
PENELLOPE: the ESO data legacy program to complement the Hubble UV Legacy Library of Young Stars (ULLYSES) I. Survey presentation and accretion properties of Orion OB1 and -Orionis
C. F. Manara, A. Frasca, L. Venuti +69
The evolution of young stars and disks is driven by the interplay of several processes, notably accretion and ejection of material. Critical to correctly describe the conditions 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…
Slingshot prominences: coronal structure, mass loss and spin down
M. Jardine, A. Collier Cameron, J. -F. Donati +1
The structure of a star's coronal magnetic field is a fundamental property that governs the high-energy emission from the hot coronal gas and the loss of mass and angular momentum…
The magnetic propeller accretion regime of LkCa 15
J-F Donati, J Bouvier, SH Alencar +12
We present a spectropolarimetric study of the classical T Tauri star (cTTS) LkCa 15 investigating the large-scale magnetic topology of the central star and the way the field connec…
Inner disk structure of the classical T Tauri star LkCa 15
S. H. P. Alencar, J. Bouvier, J. -F. Donati +15
Magnetospheric accretion has been thoroughly studied in young stellar systems with full non-evolved accretion disks, but it is poorly documented for transition disk objects with la…
Observing the simulations: Applying ZDI to 3D non-potential magnetic field simulations
L. T. Lehmann, G. A. J. Hussain, M. M. Jardine +2
The large-scale magnetic fields of stars can be obtained with the Zeeman-Doppler-Imaging (ZDI) technique, but their interpretation is still challenging as the contribution of the s…
Star-spot distributions and chromospheric activity on the RS CVn type eclipsing binary SV Cam
H. V. Şenavcı, E. Bahar, D. Montes +5
Using a time series of high-resolution spectra and high-quality multi-colour photometry, we reconstruct surface maps of the primary component of the RS CVn type rapidly rotating ec…
