We present optical and infrared photometric and spectroscopic studies of two Be stars in the 70–80-Myr-old open cluster NGC 6834. NGC 6834(1) has been reported
We aim at deriving accurate atmospheric parameters and chemical abundances of 19 barium(Ba) stars, including both strong and mild Ba stars, based on the high si
Following the theory of relativity, in the presence of an ultrastrong magnetic field (UMF) and utilizing a nuclear shell model, we carry out an estimation of th
