HVS7: a chemically peculiar hyper-velocity star [PDF]
Astronomy & Astrophysics, 2008 Context: Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelerates one component of the binary to beyond the Galactic escape velocity ...

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

Chemically peculiar stars as seen with 2MASS [PDF]
Astronomy & Astrophysics, 2015 The chemically peculiar (CP) stars of the upper main sequence are well suited for investigating the impact of magnetic fields and diffusion on the surface layers of slowly rotating stars. They can even be traced in the Magellanic Clouds and are important

Binary fraction of magnetic chemically peculiar stars [PDF]
Contributions 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.

Chemically Peculiar Stars in the Open Cluster Stock 2 [PDF]
Astronomical Journal, 2022 The recently rediscovered open cluster Stock 2, located roughly 375 pc away and about 400 Myr old, has the potential to be an exciting new testbed for our understanding of stellar evolution.

Spectropolarimetry of Magnetic Chemically Peculiar Stars in the Orion OB1 Association [PDF]
, 2022 We summarise the results of a spectropolarimetric survey of 56 chemically peculiar (CP) stars in the association of Orion OB1. We uniformly collected the observational material with the 6-m telescope BTA of the Special Astrophysical Observatory in 2013 ...

The detection of magnetic chemically peculiar stars using Gaia BP/RP spectra [PDF]
Astronomy & Astrophysics, 2022 The magnetic chemically peculiar (mCP) stars of the upper main sequence are perfectly suited to studying the effects of rotation, diffusion, mass-loss, accretion, and pulsation in the presence of an organized stellar magnetic field.

New magnetic chemically peculiar stars and candidates in the ATLAS first catalogue of variable stars [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The number of known variable stars has increased by several magnitudes over the last decade, and automated classification routines are becoming increasingly important to cope with this development.

Chemically Peculiar Stars in Integrated Light Stellar Population Models and Local Group Galaxies [PDF]
, 2022 Integrated-light models that incorporate common types of chemically peculiar (CP) stars are assembled using synthetic spectra. Selected spectral features encode significant age information for populations with ages $\sim$50 Myr $

Twenty-year monitoring of the surface magnetic fields of chemically peculiar stars [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Magnetic chemically peculiar stars of the main sequence can present rotational periods as long as many decades. Here we report the results of an observational campaign started in 2001 aimed at establishing these very long periods from the variability ...
