The stellar metallicity distribution of stars can be a very useful tool to constrain the chemical evolution models reproducing different formation scenarios for...

Knowledge of vertical structure of the turbulence in a site is an essential input for the requirements, performances and operation of Adaptive Optics systems...

The proper characterisation of the turbulence structure in an astronomical site requires an statistical study of the refractive-index structure constant Cn2(h)...

The measurement of the Sr I line with full polarimetry and spatial resolution with THEMIS has provided the unexpected result of an apparent correlation between...

Statistics are presented covering 20 years of use of the 2.1m telescope of the Observatorio Astronómico Nacional at San Pedro Mártir, Baja California, Mexico...

The role of the magnetic fields in the formation and quenching of stars with different mass is unknown. We studied the energy balance and the star formation...

During the late subgiant/early giant stage, stars undergo fast evolutionary changes such as the readjustment of their internal rotation. It is of paramount...
