Stellar multiplicity is a common consequence of the stellar formation process. Low-mass stars are the prime constituent of the nearby stellar population, with late-type accounting for the majority of the hydrogen-fusing objects in the Solar neighborhood. The CARMENES input catalogue of M dwarfs (Carmencita) is a comprehensive and homogeneous sample

Low-mass X-ray binaries (LMXB) are stellar systems where a neutron star or a black hole accretes mass from a low-mass ($\lesssim$ 1M$_\odot$) donor star. A subclass, so-called X-ray transients, spend most of their lives in a dim, quiescent state. However, these systems go into sporadic, powerful outbursts produced by one of the most energetic

In this contribution, we will show our results from a sample of 20 pairs of nearby seemingly isolated twin galaxies differing in nuclear activity. Firstly, we present a comparison of the parameter of the spin ($\lambda_{R}$), measured in a region dominated by the galaxy disc. This parameter allows us to assess the rotational support of a galaxy

Massive stars condition the evolution of the interstellar medium by the amount of energy released during their lives and especially by their deaths as supernova explosions. The vast amounts of spectroscopic data for massive stars provided by previous and existing instruments on ground-based and space-based telescopes have already saturated our

In the last decades important improvements have been made towards better access and working conditions for women in science. However, we are still far from reaching gender equality in the scientific field. We still suffer from gender stereotypes during childhood, subtle gender bias in academic and scientific evaluations, unequal work-life

Using spectral data from the SAMI Integral Field Spectrograph and full spectral fitting techniques, we obtain and study the stellar population properties of a sample of dwarf galaxies in the Fornax Cluster. Our analysis focuses on the relation of stellar populations properties with the environment and internal properties of dwarfs. We covered the
