δ Sct are one of the most abundant pulsating stars in our Galaxy. In addition, they have moderate to fast rotations and periods of several hours. That makes them the suitable targets for studying the effects of rotation on stellar evolution. In this work, we show how to infer the mean density and the surface gravity of an A-type pulsanting star

LoTr 5 is a planetary nebula with an unusual long-period binary central star. The pair consists of a rapidly rotating G-type star and a hot star, which is responsible for the ionization of the nebula. Both components are in a wide orbit with a period of about 2700 days, one of the longest in central star of planetary nebulae. In this contribution

The study of minor planets is motivated both by fundamental science of Solar system origins (some of these bodies contain the most pristine materials from the early ages of the planetary nebula) and by practical reasons concerning space exploration and impact frequency with Earth. Among minor bodies, near-Earth asteroids are a particularly

NSVS 10653195 is a double-line detached eclipsing binary star found in 2007 by te{coughlin2007} among the NSVS periodic variable stars. The first analysis of the optical VRI light curves by te{coughlin2007} show that this binary could be composed by two low mass stars. Other authors analyzed new optical light curves for this system, obtaining some

Context. Asteroid (2579) Spartacus is a small V-type object located in the inner main belt. This object shows spectral characteristics unusual for typical Vestoids, which may indicate an origin deeper than average within Vesta or an origin from an altogether different parent body. Aims: Our main goal is to study the origin of Spartacus. We derive

Context. We present the first high-cadence multiwavelength radial-velocity observations of the Sun-as-a-star, carried out during 57 consecutive days using the stellar échelle spectrograph at the Hertzsprung SONG Telescope operating at the Teide Observatory. Aims: Our aim was to produce a high-quality data set and reference values for the global
