Description


We study the rotational modulation of chromospheric and photospheric parameters of the young, active, single K2 dwarf LQ Hya and their connection with the variability of the LiI 670.8nm line. A total of 199 high-resolution STELLA spectra were used to compute effective temperature, gravity, and chromospheric activity indicators like H{alpha} and H{beta} emission, Balmer decrement, and chromospheric electron density, as a function of the rotational phase. The variation of the LiI 670.8nm line were characterized in terms of equivalent width, abundance, and of ^6^Li/^7^Li isotopic ratio in the form of line shifts.
