We present an online catalog for dwarfs with spectral types M, L and T. The catalog currently contains 893 objects listed in order of right ascension. For most...

The IAC is currently developing two similar polarimeters, one for optical wavelengths and one for near infra-red wavelengths (1.5 mu m). Both instruments will...

In this contribution I describe the main characteristics of the inversion codes developed at the Instituto de Astrofísica de Canarias for the analisys of Stokes...

We present new deep co-adds of data taken within Stripe 82 of the Sloan Digital Sky Survey (SDSS), especially stacked to reach the faintest surface brightness...

The IAC Stripe 82 Legacy Survey is a new co-addition of the SDSS Stripe 82 data (Abazajian et al. 2009), especially reduced to preserve the faintest surface...

Here we report the main characteristics of the recently acquired near infrared camera. It is based on a 256x256 HgCdTe Nicmos-3 array, sensitive from 1 mu m to...

We present the IACOB grid-based automatic tool for the quantitative spectroscopic analysis of O-stars. The tool consists of an extensive grid of FASTWIND models...
