Zodiacal light photopolarimetry. III - All-sky survey from Teide 1964-1975 with emphasis on off-ecliptic features
Photopolarimetric observations of the zodiacal light over a complete solar cycle are used to study the average distribution of brightness and degree of...
ZW 0855+06: A Wolf-Rayet Dwarf Galaxy Triggered by a Dwarf-Dwarf Interaction
We present narrowband (Hα and adjacent continuum) and broadband (B and V) optical images of the dwarf Wolf-Rayet galaxy Zw 0855+06 and its companion, together...
[Mg/Fe] and variable initial mass function: Revision of [α/Fe] for massive galaxies
Observations of nearby massive galaxies have revealed that they are older and richer in metals and magnesium than their low-mass counterparts. In particular...
``Explosion'' and Intensification of Magnetic Flux Tubes
A magnetic flux tube anchored at the bottom of the solar convection zone and rising toward the surface as a result of an undulatory instability can be affected...

Resumen: Durante campañas realizadas la década pasada en el marco de la Misión Arqueoastronómica del Egipto antiguo se estudiaron los templos de Deir el-Bahari...
ɛ Indi Ba, Bb: a detailed study of the nearest known brown dwarfs
The discovery of ɛ Indi Ba, Bb, a binary brown dwarf system very close to the Sun, makes possible a concerted campaign to characterise the physical parameters...
We have carried out high angular resolution near-infrared imaging and low-resolution (R˜1000) spectroscopy of the nearest known brown dwarf, varepsilon Indi B...
