New catalogue of chemically peculiar stars, and statistical analysis [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
In this paper we present a new catalogue of Chemically Peculiar (CP) stars obtained by compiling publications in which abundances of metals are provided. Our catalogue includes 428 stars for which the data were obtained through spectroscopic observations.

The Kepler view of magnetic chemically peculiar stars [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that allow the investigation of such diverse phenomena as atomic diffusion, magnetic fields, and stellar rotation. The advent of space-based photometry provides the opportunity

Binary fraction of magnetic chemically peculiar stars [PDF]

open access: yesContributions of the Astronomical Observatory Skalnaté Pleso, 2020
Magnetic chemically peculiar stars of the upper main sequence are slowly rotating early B to early F-type objects with elemental overabundances of several orders of magnitude compared to the Sun.

Multiplicity among chemically peculiar stars [PDF]

open access: yesAstronomy & Astrophysics, 2002
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 22128, HD 56495 and HD 98088. The twelve other stars are : HD 9996, HD 12288, HD 40711, HD 54908, HD 65339, HD 73709, HD 105680, HD 138426, HD 184471, HD 188854, HD 200405 and ...

A New Catalog of Am-type Chemically Peculiar Stars Based on LAMOST

open access: yes, 2023
A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Releases 8 (v1.0), 9 (v0), and 10 (v0), which greatly expands the database

Radio detection of chemically peculiar stars with LOFAR

open access: yesAstronomy & Astrophysics, 2022
Context. Chemically peculiar stars are upper main sequence stars that show anomalies in their optical spectra. These anomalies suggest peculiar chemical abundances of certain elements.

Magnetic Chemically Peculiar Stars [PDF]

open access: yes, 2014
Chemically peculiar (CP) stars are main-sequence A and B stars with abnormally strong or weak lines for certain elements. They generally have magnetic fields and all observables tend to vary with the same period. Chemically peculiar stars provide a wealth of information; they are natural atomic and magnetic laboratories.
