Absolute magnitudes for late-type dwarf stars for Sloan photometry
S. Bilir, S. Karaali, S. Tuncel
We present a new formula for absolute magnitude determination for late-type dwarf stars as a function of (g-r) and (r-i) for Sloan photometry. The absolute magnitudes estimated by…

New colour-transformations for the Sloan photometry and revised metallicity calibration and equations for photometric parallax estimation
S. Karaali, S. Bilir, S. Tuncel
We evaluated new colour-transformations for the Sloan photometry by 224 standards and used them to revise both the equations for photometric parallax estimation and metallicity cal…
