The spatial distribution of Cyg OB2 from {it Gaia} DR2
A key difficulty in the study of Milky Way massive stars and OB associations has been the large uncertainty in their distances, hindering the comparison with...
The Spatial Distribution of the He II λ4686 Emission Line in Compact H II Galaxies
In this work, based on Integral Field Unit spectroscopy observations on the Gemini South telescope, we study the spatial distribution of the He II λ4686...
The Spectral Energy Distribution of the Central Parsecs Region of Galaxies
Genuine spectral energy distributions (SED) of the central few parsec region of the nearest and brightest active galaxies in the southern hemisphere are...
The Spectroscopic Observations of CoRoT Asteroseismic Targets with HARPS
CoRoT photometric measurements of asteroseismic targets need complementary ground-based spectroscopic observations. We are using the planet-hunter HARPS...
The Spectroscopic Period of the Cataclysmic System Am-Canum
We present some preliminary results of a time-resolved spectroscopic study of the peculiar cataclysmic system AM CVn. The analysis of He i lines profile...
The spectroscopic properties of the Lixiaohua Family, cradle of Main-Belt comets
We present an analysis of the spectroscopic properties of the Lixiaohua asteroid family, which hosts two main-belt comets. This study will enhance our knowledge...
The Spectrum of Solar p-Modes and the Solar Activity Cycle
Solar cycle variations on the power and frequencies of the low l p-mode solar acoustic oscillations are investigated using an extensive set of observations...
