Observations of the Local Arm have been carried out in the near-infrared with the 1.5 m ``Carlos Sanchez'' telescope in Tenerife. A model of the disc with...

We present a first study of truncation of the stellar disks of spiral galaxies in the near infrared. Observations of NGC 4013, NGC 4217, NGC 6504 and NGC 5981...

We present the near infrared photometry of a new sample of 225 IRAS sources, many of them previously unidentified in the literature, selected because their far...

Aims: Our goal is to study the physical properties of the circumstellar environment of young stellar objetcs (YSOs). In particular, the determination of the...

We present near infrared reflectance spectra from 0.8 to 2.5 μm of two asteroids with low Tisserand invariant, 1373 Cincinnati and 2906 Caltech. We compare our...

A model of the galactic stellar distribution has been developed and the surface stellar densities in the near infrared are compared with observations along the...

Near-IR standard photometry (J, H, K, L and M bands) of 38 IRAS sources with FIR colors similar to those of known planetary nebulae is presented. They are...

A new method of representing star count data is shown which has the advantage over traditional methods of giving clear insights into the luminosity functions...

In three-dimensional (3D) radiative transfer (RT) problems, the tensor product quadratures are generally not optimal in terms of the number of discrete ray...
