The Near-Infrared S0 Survey (NIRS0S; Laurikainen, Salo, and Buta 2005, MNRAS, 362, 1319) is an attempt to obtain a statistically well-defined database of images of S0s from which the properties of S0 bars may be fairly compared to those of spirals. The main goal of the survey is to provide information on the the distribution of bar strengths in S0

The solar magnetism is no more considered as a purely superficial phenomenon. The SoHO community has shown that the length of the solar cycle depends on the transition region between radiation and convection. Nevertheless, the internal solar (stellar) magnetism stays poorly known. Starting in 2008, the American instrument HMI/SDO and the European

We lack a reliable scenario for the formation and evolution of stars and their planetary systems, involving key factors such as magnetic fields and turbulence. We present the case for a mission concept that will clarify these problems and give us a global view of the evolution of combined star and planetary systems. This will be achieved by

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 of them the spectra can be downloaded from the catalog in ASCII or FITS formats. The web address is http://www.iac.es/galeria/ege/catalogo_spectral/.

The Instituto de Astrofisica de Canarias (IAC) is a Spanish research centre. It comprises the Instituto de Astrofisica, the main headquarters in La Laguna (Tenerife), the Teide Observatory in Izaña (Tenerife) and the Roque de los Muchachos Observatory, in Garafia on La Palma. Whilst maintaining a level of excellence, not only for the facilities of
