Low-frequency p-modes have relatively small amplitudes and are set against the background of granulation on the solar surface. In this work, the calibrated...

Integral-field spectroscopy techniques are ideal to study objects of complex morphology and kinematics such as the circumnuclear region of AGN. We have obtained...

White dwarf masses can be determined in several ways. Here we compare masses obtained from Balmer line spectroscopy with those derived from trigonometric...

By using the Synspec program with different LTE and NLTE atmospheric models of Alpha Lyrae (Vega, spectral type A0V), we obtain different emitted fluxes. Taking...

We review the needs of the CoRoT /exoplanet program in terms of complementary observations. Such observations are indeed an essential element of the science of...

The extraction of resonance parameters from meson photo-reaction data is a challenging effort, that would greatly benefit from the availability of several...

We propose to complete our program of optical imaging of a sample of candidate strong-lensing galaxies discovered in the Herschel Multi-tiered Extragalactic...

The Adaptive Optics Lucky Imager (AOLI) is a new instrument designed to combine adaptive optics (AO) and lucky imaging (LI) techniques to deliver high spatial...
