It is foreseen that Extremly large telescope (ELT) will include Adaptive Optics Systems to provide diffraction-limited images in the near infrared. The...
We present spectroscopy of the Hα emision line in the X-ray transient V4 04 Cyg. Along with the spectroscopy, simultaneus photometry was used in order t o...
Benchmark brown dwarf companions as exoplanets analogues
Directly imaged substellar companions around stars are key objects for better understanding the formation and evolution of brown dwarfs and massive planets, as...
Benchmark Brown Dwarfs: What Does the Current Population Look Like?
Since the discovery of the first brown dwarfs (Tiede 1; Rebolo et al. 1995, Gliese 229B; Nakajima et al. 1995) the complement of identified brown dwarfs has...
Benchmark ultra-cool dwarfs in widely separated binary systems
Ultra-cool dwarfs as wide companions to subgiants, giants, white dwarfs and main sequence stars can be very good benchmark objects, for which we can infer...
BeppoSAX-WFC monitoring of the Galactic Center region
We review the results obtained with the Galactic center campaigns of the BeppoSAX Wide Field X-ray Cameras (WFCs). This pertains to the study of luminous low...
BeppoSAX-WFCs monitoring of the high-mass X-ray binary 4U 1700-377
During the whole operational lifetime of the BeppoSAX X-ray satellite, the Galactic bulge region was monitored in the 2-28 keV band through dedicated...
