Catalogue of Am/Fm Variability
We aim to study chemically peculiar Am and Fm stars, distinguished by their unique abundance patterns, which are crucial for studying mixing processes in intermediate-mass... -
Am stars selected in LAMOST DR8-DR10
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... -
Radial velocity and transit photometry of TOI-1431
We present the discovery of a highly irradiated and moderately inflated ultrahot Jupiter, TOI-1431b/MASCARA-5 b (HD201033b), first detected by NASA's Transiting Exoplanet Survey... -
Spectroscopically identified CVs from LAMOST survey. I.
A sample of cataclysmic variables (CVs) is presented including spectroscopically identified 380 spectra of 245 objects, of which 58 CV candidates are new discoveries. The... -
Differential photometry of HD 8801
We have discovered the first example of a star pulsating intrinsically with both {gamma} Doradus and {delta} Scuti frequencies. HD 8801 is an Am metallic-line star that appears... -
ubvy{Delta}a photometry of Renson stars
Results of 131 stars from Renson's (1991, Cat. ) catalogue of Ap and Am stars observed with the {Delta}-a system are presented. With few exceptions the probability division of... -
PCA-based inversion of stellar parameters
We present an automated procedure that simultaneously derives the effective temperature Teff, surface gravity logg, metallicity [Fe/H], and equatorial projected rotational... -
uvby photometry of 2 Am and 2 mCP stars
Differential Stroemgren uvby observations from the Four College Automated Photoelectric Telescope (FCAPT) are presented for the metallic-lined stars 60 Tau and HR 1528 and the... -
Am and Ap star candidates from LAMOST DR10
Large samples of Am and Ap stars are helpful in studying the interplay between phenomena like atomic diffusion, magnetic fields, and stellar rotation in stellar astrophysics.... -
SuperWASP observations of pulsating Am stars
We have studied over 1600 Am stars at a photometric precision of 1mmag with SuperWASP photometric data. Contrary to previous belief, we find that around 200 Am stars are... -
LAMOST parameters of Am and non-chemical-peculiar stars
Rotation is a critical physical process operating in the formation of Am stars. There is a strong correlation between low-velocity rotation and chemical peculiarity. However,... -
Velocity curves of SW CMa and HW CMa
Accurate physical properties of eclipsing stars provide important constraints on models of stellar structure and evolution, especially when combined with spectroscopic... -
Radial velocities of HD 209625
The goal is to test the structure of hot metallic stars, and in particular the structure of a near-surface convection zone using asteroseismic measurements. Indeed, stellar... -
Radial velocities of Praesepe & Hyades Am stars
CORAVEL radial-velocity observations of Am stars in the Hyades and Praesepe have allowed the determination of orbital elements for 10 spectroscopic binaries, among which 3 are...
