We present 64 photoelectric minima observations of 31 eclipsing binaries. We also report three new times of maxima of three SXPHE type pulsating stars.

We present 42 photoelectric minima observations of 24 eclipsing binaries.

Context. The first generation of stars formed in the Galaxy left behind the chemical signatures of their nucleosynthesis in the interstellar medium, visible...

Aims: We aim to develop an efficient method to search for late-type subdwarfs (metal-depleted dwarfs with spectral types ≥M5) to improve the current statistics...

Aims: The aim of the project is to improve our knowledge of the low-mass and low-metallicity population to investigate the influence of metallicity on the...

Context: The compact association Cygnus OB2 is known to contain a large population of massive stars, but its total mass is currently a matter of debate. While...

We present VR magnification ratios of QSO 0957+561 that are inferred from the GLITP light curves of Q0957+561A and new frames taken with the 2.56 m Nordic...

Aims: We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. The IPHAS catalogue of Hα-emitting...

Context. Exploding granules have drawn renewed interest because of their interaction with the magnetic field (either emerging or already present). Especially...
