  • CP stars magnetic fields catalog (2007)

    This catalog presents the results of magnetic field measurements for 39 chemically peculiar and 3 normal main sequence stars used as standard stars. Observations were carried...
  • Polarisation and magnetic fields in Ap stars

    In this paper we describe and evaluate new spectral line polarization observations obtained with the goal of mapping the surfaces of magnetic Ap stars in great detail. One...
  • Magnetic fields of chem. peculiar stars

    Spectropolarimetric observations of 96 chemically peculiar (CP) main-sequence stars have been carried out at the 6-m telescope at the Special Astrophysical Observatory of the...
  • New IR photometric study of Ap and Am stars

    In this paper, 426 well known confirmed Ap and Am stars are photometrically studied in the infrared. The 2MASS, Wide-field Infrared Survey Explorer (WISE), and IRAS data are...
  • GO And, 84 UMa, kappa Psc ESPaDOnS spectra

    The aim of this work is to determine fundamental parameters of three Ap stars, GO And (HD 4778), {kappa} Psc (HD 220825), and 84 UMa (HD 120198), using spectroscopic techniques....
  • Gaia DR2-based catalogue of 237 Ap stars

    Knowing the distribution of strongly magnetic Ap stars in the Hertzsprung-Russell diagram (HRD) allows us to study the evolution of their magnetic fields across the main...
  • Multiplicity among chemically peculiar stars II

    We present new orbits for sixteen Ap spectroscopic binaries, four of which might in fact be Am stars, and give their orbital elements. Four of them are SB2 systems: HD 5550, HD...
  • Catalogue and Bibliography of Mn-Hg Stars

    In the present catalogue all Ap stars of the type Mn-Hg, Mn or Hg are summarized. Also, the stars which are suspected to be of this type are included. If in the literature two...
  • Speckle interferometry of Ap stars. II.
