We present preliminary results of a simultaneous X-ray/optical campaign of the prototypical LMXB Sco X-1 at 1 10 Hz time resolution. Lightcurves of the high...
The OJ-94 international collaboration has been observing the light curve of OJ287 intensely at radio, millimetric, infrared and visible wavelengths. We present...
Multiband observations of the comet C/2000 WM1 (LINEAR) at its closest approach to the Earth
Comet C/2000 WM1 (LINEAR) was observed at ESO when it had its closest approach to the Earth at the beginning of December 2001 (geocentric distance: 0.32 AU)...
Multiband photometry of asteroid 596 Scheila after its December 2011 outburst
An unexpected dust cloud was identified around asteroid 596 Scheila on early December 2010 [1]. Our team has been monitoring its photometric behavior in order...
The authors present the first results of their multicolor polarimetric study of stars in the association Ara OB1. Stars belonging to the clusters NGC 6204, NGC...
Multicolour observations of V404 Cyg and J1118+480 with ULTRACAM
We present high time-resolution multicolour observations of the quiescent soft X-ray transients V404 Cyg and XTE J1118+480 obtained with ULTRACAM. The power...
Simultaneous multicolor photometry is an important source of observational data providing priceless information on different physical processes that cannot be...
