Desde el comienzo de la astrofísica extragaláctica en los años 30 - gracias al trabajo de Edwin Hubble quien constató que nuestra galaxia era solamente una entre millones - el estudio de la formación y evolución de galaxias se ha convertido en un sector muy estudiado dentro de la investigación astrofísica. Se han hecho enormes esfuerzos para

The molecular carriers of the ubiquitous absorption features called the diffuse interstellar bands (DIBs) have eluded identification for many decades, in part because of the enormous parameter space spanned by the candidates and the limited set of empirical constraints afforded by observations in the diffuse interstellar medium. Detection of these

We used a new generation of asymptotic giant branch (AGB) stellar models that include dust formation in the stellar winds to find the links between evolutionary models and the observed properties of a homogeneous sample of Large Magellanic Cloud (LMC) planetary nebulae (PNe). Comparison between the evolutionary yields of elements such as CNO and

We will present results of a survey of Hilda asteroids to look for extreme shape objects. We used WISE [1, 2] sparse IR photometry to identify objects with high photometric variability in different bands. Highly variable candidates were targeted by densely sampled, follow-up ground-based photometry. Similar strategies were successfully used to

Context. Solar-like oscillations have been observed by Kepler and CoRoT in many solar-type stars, thereby providing a way to probe stars using asteroseismology. Aims: The derivation of stellar parameters has usually been done with single stars. The aim of the paper is to derive the stellar parameters of a double-star system (HIP 93511), for which

Jupiter's atmosphere has been sounded in transmission from UV to IR, as if it were a transiting exoplanet by observing one of its satellites, Ganymede, while passing through Jupiter's shadow during a solar eclipse from Ganymede. The spectra show strong extinction due to the presence of aerosols and haze in the atmosphere and strong absorption
