Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon place this knowledge into a broader context by providing structural data for hundreds of Sun-like stars. Solar-like oscillations have already been detected from the ground in several stars

Context: Infrared (IR) spectroscopy and imaging provide a prime tool to study the characteristics of polycyclic aromatic hydrocarbon (PAH) molecules and the mineralogy in regions of star formation. Herbig Ae/Be stars are known to have varying amounts of natal cloud material present in their vicinity. Aims: Our aim is to study the characteristics of

A variety of physical processes leading to different types of pulsations and chemical compositions are observed between A- and F-type stars. To investigate the underlying mechanisms responsible for these processes in stars with similar locations in the Hertzsprung-Russell diagram, an accurate abundance determination is needed, among others. Here

Las nebulosas planetarias (NPs) se descubrieron hace casi tres siglos y desde entonces se han convertido en una herramienta importante para estudiar diferentes problemas astron\'omicos. Sin embargo, aún están abiertas cuestiones importantes relacionadas con estos objetos. No existe una información global sobre la poblaci\'on real de NPs gal\

La calibración fotométrica es actualmente uno de los mayores retos técnicos de la astronomía, ya que necesita de muy alta precisión en un muy amplio rango dinámico. Una estimación precisa de los errores, que podrán afectar a las medidas que se obtienen de los objetos que nos interesa estudiar, garantiza la fiabilidad de la ciencia que se produce
