Very high energy γ-radiation from the radio quasar 4C 21.35
A very high energy (VHE) γ-radiation was detected from a flat spectrum radio quasar (FSRQ) 4C 21.35 (PKS1222+21) by MAGIC (Major Atmospheric Gamma Imaging...
Very high spatial resolution study of multiplicity in T Tauri systems
We present first relevant results from our survey to search multiplicity in T Tauri systems and its relation with disk presence and planet formation on these...
Very low mass stars in Praesepe (Boudreault+, 2010)
The near-infrared (NIR) observations were made on the 3.5m telescope at Calar Alto, Spain (with observation runs of several nights from February 2005 to January...
Very low-luminosity Class I/Flat outflow sources in sigma Orionis: Clues to alternative formation mechanisms for very low-mass stars
We present an optical through sub-millimetre multi-wavelength study of two very low-luminosity Class I/Flat systems, Mayrit 1701117 and Mayrit 1082188, in the...
Here is a state-of-the-art review of our current knowledge of brown dwarfs and very low-mass stars. The hunt for, and study of, these elusive objects is...
