We present simultaneous and continuous observations of Hα, Hβ, ion{Na}{1} D1, D2, ion{He}{1} D3 and ion{Ca}{2} H & K lines of the chromospherically active...
MUSICOS 1998: Optical and X-rays Observations of Flares on the RS CVn Binary HR 1099
We present simultaneous and continuous observations of H_alpha, H_beta, NaI D_1, D_2 and HeI D_3 lines of the chromospherically active binary HR 1099. We have...
Mysteries of Mass: Some Contrarian Views From an Experimenter
Physics and astronomy are the oldest sciences and the concept of mass is thus a very old concept. We have quite good understanding of the masses of composite...
NAHUAL: a near-infrared high-resolution spectrograph for the GTC optimized for studies of ultracool dwarfs
We present the status of an ongoing study for a high-resolution near-infrared echelle spectrograph for the 10.4-m GTC (Gran Telescopio de Canarias) which will...
NAHUAL: A Next-Generation Near Infrared Spectrograph for the GTC
The extension of the highly successful Doppler technique into the near-infrared (0.9-2.5 μm) is opening new parameter domains for extra-solar planet searches in...
