This study presents the multi-wavelength investigation of the absolute magnitudes and colours of the red clump (RC) stars selected from APOGEE and GALAH DR2 combined catalogue which is complemented with {\it Gaia} DR2 astrometric data and multi-wavel

We derive transformation equations between GALEX and UBV colours by using the reliable data of 556 stars. We present two sets of equations; as a function of (only) luminosity class, and as a function of both luminosity class and metallicity. The meta

The insufficiency of photometric data in the U-band of the FGK-type stars in the solar neighborhood makes difficult to determine the flux of the blue region of their spectral energy distributions, and causes to the inadequacy in the estimation of the

We aim to probe the dynamic structure of the extended Solar neighbourhood by calculating the radial metallicity gradients from orbit properties, which are obtained for axisymmetric and non-axisymmetric potential models, of red clump (RC) stars select

We used the SDSS magnitudes of about 1.5 million F and G type main-sequence stars with metallicity and distances and estimated vertical metallicity gradients for middle/high Galactic-latitude fields of the Milky Way. The vertical metallicity gradient

We present the calibration of the [$\alpha/$Fe] element in terms of ultra-violet excess for 465 dwarf stars with spectral type F0-K2. We used a single calibration, fitted to a third degree polynomial with a square of the correlation coefficient 0.74
