Aims: The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number of host stars listed there. A crucial step toward a comprehensive understanding of these new worlds is the precise and homogeneous characterization of their host stars

Asteroseismology of bright stars has become increasingly important as a method to determine the fundamental properties (in particular ages) of stars. The Kepler Space Telescope initiated a revolution by detecting oscillations in more than 500 main-sequence and subgiant stars. However, most Kepler stars are faint and therefore have limited

We report the discovery of an ultrahot Jupiter with an extremely short orbital period of 0.67247414 ± 0.00000028 days (~16 hr). The 1.347 ± 0.047 R Jup planet, initially identified by the Transiting Exoplanet Survey Satellite (TESS) mission, orbits TOI-2109 (TIC 392476080)-a T eff ~ 6500 K F-type star with a mass of 1.447 ± 0.077 M ☉, a radius of 1

RESUMEN: En este trabajo se examina, desde la perspectiva de la Astronomía Cultural, si las iglesias románicas del Camino de Santiago siguen un patrón de orientación común a todas ellas. Para ello, se ha obtenido la orientación Ambos reinos comparten orientaciones hacia la salida del sol el domingo de Pascua, probablemente obtenidas en su mayoría
