Sulphur abundances from the SI near-infrared triplet at 1045 nm (2007)
Caffau, Elisabetta, Faraggiana, Rosanna, Bonifacio, Piercarlo, Ludwig, Hans-G., Steffen, Matthias
context : Unlike silicon and calcium, sulphur is an alpha-element which does not form dust. Some of the available observations of the evolution of sulphur with metallicity indicate an increased...

How many lambda Boo stars are binaries ? (1999)
Faraggiana, Rosanna, Bonifacio, Piercarlo
In the attempt to shed new light on the lambda Boo phenomenon we analyzed the astrometric, photometric and spectroscopic characteristics of stars out of a list of recently selected lambda Boo...
ZODIACAL LIGHT AND ITS CORRELATION WITH SOLAR ACTIVITY. (1998)
Hack,Margherita, Faraggiana,Rosanna, Flora,Umberto
Photographic observations of the Zodiacal Light in two colors (blue and yellow) and two polarizations (parallel and perpendicular to the ecliptic) have been made from the high altitude station of the...
