The magnetic field of the chemically peculiar star V352 Peg [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
ABSTRACTWe present a spectropolarimetric analysis of the hot star V352 Peg. We have acquired 18 spectropolarimetric observations of the star with ESPaDOnS at the CFHT between 2018 and 2019 and completed our data set with one archival ESPaDOnS measurement obtained in 2011.

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.

The 5200-Å flux depression of chemically peculiar stars – II. The cool chemically peculiar and λ Bootis stars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
After establishing the synthetic ?a photometric system in the first paper of this series, we now present model atmospheres computed with individual abundances for a representative sample of chemically peculiar (CP) stars and either confirm or redetermine their input parameters through comparisons with photometric, spectrophotometric and high-resolution

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 ...

HVS 7: a chemically peculiar hyper-velocity star [PDF]

open access: yesAstronomy & 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. Aims: The evolutionary status and GC origin of the HVS SDSS J113312.12+010824.9 (HVS7) is constrained ...

Asteroseismology of chemically peculiar stars [PDF]

open access: yesCommunications in Asteroseismology, 2009
Pulsational variability is observed in several types of main sequence stars with anomalous chemical abundances. In this contribution I summarize the relationship between pulsations and chemical peculiarities, giving special emphasis to rapid oscillations in magnetic Ap stars.

Chemically peculiar stars as seen with 2MASS [PDF]

open access: yesAstronomy & 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 to the understanding of the stellar formation and evolution. A systematic investigation of the near-
