CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including...

We present a preliminary analysis of public, deep (200 ksec.) Chandra/ACIS observations of three fields comprising the original Groth-Westphal strip (GWS)...

We report an outburst of a black hole X-ray binary, V4641 Sgr in 2004 July. We succeeded in performing time-series photometry during the outburst, which showed...

We present our recent results on the properties of the outskirts of disk galaxies. In particular, we focus on spiral galaxies with stellar disk truncations in...

We present the oxygen abundance determination for 90 HII regions in the inner parts of the grand design galaxy M101. The abundances were derived employing the P...

To build a catalogue that satisfies our requirements of spectroscopic and photometric completeness, we used a set of galaxies derived from the Millennium Galaxy...

The authors present the results of narrow-band filter photometry of Periodic Comet Faye obtained from Estacion Astronomica "Dr. Carlos U. Cesco" of Felix...

We present results of photometry and photopolarimetry of the Wolf-Rayet eclipsing binary system HD 5980 in the Small Magellanic Cloud, which underwent an...

Shakhbazian compact galaxy groups are the most dense configurations known. A few years ago we commenced a detailed spectral and photometric study of these...
