  In the framework of the GIARPS@TNG High-resolution Observations of T Tauri
stars (GHOsT) project, we study the accretion properties of 37 Classical T
Tauri Stars of the Taurus-Auriga star forming region (SFR) with the aim of
characterizing their relation with the properties of the central star, of jets
and disk winds, and of the global disk structure, in synergy with complementary
ALMA millimiter observations. We derive stellar parameters, optical veiling,
accretion luminosity ($\rm L_{acc}$) and mass accretion rate ($\rm \dot
M_{acc}$) in a homogeneous and self-consistent way using high-resolution
spectra acquired at the Telescopio Nazionale Galileo with the HARPS-N and GIANO
spectrographs, and flux-calibrated based on contemporaneous low-resolution
spectroscopic and photometric ancillary observations. The $\rm L_{acc}$-$\rm
L_{\star}$, $\rm \dot{M}_{acc}$-$\rm M_{\star}$ and $\rm \dot{M}_{acc}$-$\rm
M_{disk}$ relationships of the Taurus sample are provided and compared with
those of the coeval SFRs of Lupus and Chamaeleon I. Our results demonstrate the
potential of contemporaneous optical and near-infrared high-resolution
spectroscopy to simultaneously provide precise measurements of stellar and
accretion/wind properties of young stars.
