This poster presents new results derived from spectropolarimetric and photometric observations of the young weak line T Tauri star V410 Tau, collected respectively with the new near-infrared spectropolarimeter SPIRou at CFHT, and with the TESS space probe. For the first time, we combined high-resolution spectropolarimetry and high-precision photometry with Zeeman-Doppler Imaging, in order to reconstruct maps of the photospheric brightness and of the large-scale magnetic field at the surface of V410 Tau. Our results reveal a complex magnetic field, consistent with previous studies, and a high level of stellar activity. Our study also illustrates the benefits of near-infrared (vs optical) observations, to investigate the magnetic topologies of young stars and look for the potential presence of massive planets on close-in orbits through radial velocity measurements.
