Ultra-deep optical imaging surveys have reached unprecedented depths (≳30 mag arcsec ‑2; 3σ, 10″ × 10″), thus facilitating the study of very faint galactic...

This paper presents new complete uvby light curves of the late-type detached eclipsing binary BH Vir (G0V + G5V, P=0.81687099d). This binary system has been...

This paper presents first complete uvby light curves of the late-type detached eclipsing binary ZZ UMa (G0V + G8V, P=2.2993d). This binary system has been...

We observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 to study the origin of long-term variability found in its light curve. Multi-longitude...

We present differential CCD photometry for the high-amplitude delta Scuti star V567 Ophiuchi obtained in the Johnson V-band. It was observed on 15 nights in two...

We obtained optical and near-infrared images with VRIJHKs filters between 2010 September 19 and 2012 October 12 using four telescopes: the Schmidt and RCC...

The observations were obtained with the automated 60cm telescope of Konkoly Observatory, Svabhegy, Budapest equiped with a Wright 750x1100 CCD using BV(RI)c...

The aperture photometry package "vaphot" was developed to perform reliable and precise time-series photometry of uncrowded fields. This package works within the...

We compile a database of physical parameters for the sample stars from the literature and new ground-based observations. We analyse the Kepler light curve of...
