Zeeman Doppler mapping deconstructed
M. J. Stift, F. Leone
Aims. Magnetic and abundance maps of chemically peculiar (CP) stars, derived with the help of Zeeman Doppler mapping, have invariably been used as arguments against theories, in pa…
Zeeman Doppler maps. II: the perils of eschewing physics
M. J. Stift, F. Leone
For the observational modeling of horizontal abundance distributions and of magnetic geometries in chemically peculiar (CP) stars, Zeeman Doppler mapping (ZDM) has become the metho…
Time-dependent atomic diffusion in the atmospheres of CP stars. A big step forward: introducing numerical models including a stellar mass loss
G. Alecian, M. J. Stift
Calculating abundance stratifications in ApBp/HgMn star atmospheres, we are considering mass-loss in addition to atomic diffusion in our numerical code in order to achieve more rea…
The multi-line slope method for the measure of the effective magnetic field of the cool stars: an application to the solar like cycle of ε Eri
C. Scalia, F. Leone, M. Gangi +2
A method for the determination of integrated longitudinal stellar fields from low-resolution spectra is the so-called slope method, which is based on the regression of the Stokes V…
A method to measure the transverse magnetic field and orient the rotational axis of stars
Francesco Leone, Cesare Scalia, Manuele Gangi +5
Direct measurements of the stellar magnetic fields are based on the splitting of spectral lines into polarized Zeeman components. With few exceptions, Zeeman signatures are hidden…
Three-dimensional abundance distributions in ApBp star atmospheres: non-axisymmetric magnetic geometry
G. Alecian, M. J. Stift
Numerical models for the atmospheres of magnetic ApBp stars have in the past dealt only with centred dipole magnetic field geometries. These models include atomic diffusion that st…
