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... -
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... -
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,... -
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... -
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... -
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... -
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... -
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...
