CARMENES is an instrument designed to search for extrasolar planets around M dwarfs with the radial-velocity technique. It consists of two independent high-resolution echelle spectrographs for the visible and near-infrared wavelength ranges, which are simultaneously fed through fibers from a front end at the Cassegrain focus of the 3.5m telescope

The forthcoming New Robotic Telescope, a collaboration between the UK and Spain, is poised to become the world's largest and fastest autonomous observatory, located in La Palma. It is tailored to be a premier 4m class follow-up facility for the imminent wave of time-domain and transient astrophysics. It exemplifies innovation with its use of

In this contribution we present the results from a 1 homogeneous quantitative spectroscopic analysis of ∼400 Galactic O-type stars targeted by the IACOB and OWN surveys. The ultimate objective is to perform a modern reassessment of one of the long-standing problems in the field of massive stars: the elusive detection of mid O-type stars close to
