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... -
Ap stars from LAMOST DR9 sp. and Gaia DR3
We present a sample of 2700 Ap stars in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR9 catalog. The candidates are first selected to be in a... -
Polarimetry of Ap stars: general catalogue
A systematic program of broadband linear polarimetry, bearing on 55 Ap stars, has been developed during the 4 last years, at the Pic du Midi Observatory. While separate data... -
Super-slowly rotating Ap (ssrAp) stars sample
The magnetic chemically peculiar Ap stars exhibit an extreme spread of rotational velocities, the cause of which is not clearly understood. Ap stars with rotation periods of 50... -
Spectra of 27 ssrAp star candidates
The fact that the rotation periods of Ap stars span five to six orders of magnitude and that the longest ones reach several hundred years represents one of the main unsolved... -
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... -
Radial velocities of magnetic Ap stars
Some Ap stars that have a strong enough magnetic field and a sufficiently low v sin i show spectral lines resolved into their magnetically split components. We present the... -
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... -
Catalog of magnetic CP stars (2016)
We continue the annual publications of the magnetic field measurements of chemically peculiar stars. Observations were carried out with the Main Stellar Spectrograph of the 6-m... -
Catalog of magnetic CP stars (2015)
The paper presents magnetic field measurements and physical parameters for 96 stars. Observations were carried out in 2015 with the 6-m BTA telescope using the Main Stellar... -
Magnetic fields of CP stars (2013)
We present the results of measuring longitudinal magnetic fields (B_e), rotation velocities (v_esini), and radial velocities (RV) of 107 stars observed with the Main Stellar... -
Magnetic fields of CP stars (2014)
We present the results of measuring longitudinal magnetic fields (B_e), and radial velocities (RV) of 74 stars observed with the Main Stellar Spectrograph (MSS) of the 6-m BTA... -
Ori OB1 CP stars magnetic fields. V.
The paper presents magnetic field measurements for 15 chemically peculiar (CP) stars of subgroup 1b in the Orion OB1 association. We have found that the proportion of stars with... -
Ori OB1 CP stars magnetic fields. V.
The paper presents the results of magnetic field measurements of 27 chemically peculiar stars in subgroups (c) and (d) of the Orion OB1 association. In total, more than 140... -
Magnetic fields of CP stars (2012)
We present the results of measuring longitudinal magnetic fields (Be), rotation velocities (v_esini), and radial velocities (VR) of 163 stars observed with the Main Stellar... -
Ori OB1 CP stars magnetic fields. III.
The paper presents results of magnetic field measurements of 10 chemically peculiar stars of subgroup (a) in the Orion OB1 association: HD33917, HD34859, HD35008, HD35039,... -
