We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf (WD) and a main-sequence K7 star with clear signs of chromospheric and spot activity. The light curve of this system shows ∼0.2 mag ellipsoidal variability with a period of 0.297549 d and a short total eclipse of the WD. Based on our analysis of

Presentamos un estudio de la relación entre astronomía y paisaje centrado en la orientación de las iglesias y ermitas cristianas de la isla de La Gomera, situada en el Archipiélago Canario (España). El trabajo de campo consistió en la medición de las coordenadas precisas de ubicación de 38 iglesias y ermitas, lo que representa la casi

Classical Cepheids represent the first step of the distance scale ladder. Claims of tension between the locally calculated Hubble constant and the values deduced from Planck's results have sparked new interest in these distance calibrators. Cluster membership provides an independent distance measurement, as well as astrophysical context for studies

Aims: Prior to 2019, the June epsilon Ophiuchids (JEO) were known as a minor unconfirmed meteor shower with activity that was considered typically moderate for bright fireballs. An unexpected bout of enhanced activity was observed in June 2019, which even raised the possibility that it was linked to the impact of the small asteroid 2019 MO near

We study the M-type asymptotic giant branch (AGB) population of the Large Magellanic Cloud (LMC) by characterizing the individual sources in terms of the main properties of the progenitors and of the dust present in the circumstellar envelope. To this aim we compare the combination of the spectroscopic and photometric data collected by Spitzer

Los asteroides son objetos resultantes de las colisiones y evolución dinámica de los planetesimales originarios del Sistema Solar. Algunos de estos planetesimales originarios —formados en el disco protoplanetario como consecuencia de la agregación de gas y polvo— sobrevivieron al proceso de formación planetaria y permanecen prácticamente
