Most of the spectra for the planet-host stars analyzed in this paper were studied in Papers I (Santos et al., 2000A&A...363..228S), II (Santos et al., 2001A&A...

We present the study of the metallicity dependence of the Fourier amplitude ratios R21 and R31 for the light curves of short-period Galactic classical Cepheids...

Wind fluctuations in [WC 8-9]-type central stars of planetary nebulae have been detected. Moving features seen on the top of the C III lambda 5696 and C IV...

All the observations were made at the Harlan J. Smith 2.7-m telescope at McDonald Observatory, using the 2dcoude echelle spectrometer (Tull et al., 1995PASP...

How do galaxies shape their morphology through time? How many details of galaxies at cosmic noon are we going to unveil? This contribution aims at presenting...

The discovery of V Indi Ba and Bb, a nearby binary brown dwarf system with a main-sequence companion, allows a concerted campaign to characterise the physical...

In this contribution, we show the capability of STARE to obtain frequencies and amplitudes from high temporal resolution δ Scuti spectra. Lightcurves of 13 new...
