Teaching Light Scattering Spectroscopy: The Dimension and Shape of Tobacco Mosaic Virus (2007)
ABSTRACT The tobacco mosaic virus is used as a model molecular assembly to illustrate the basic potentialites of light scattering techniques (both static and dynamic) to undergraduates. The work has...
Intrinsic Stellar Limitations to Planet Searches With Radial-Velocity Techniques (2007)
Nuno C. Santos, Michel Mayor, Dominique Naef, Francesco Pepe, Didier Queloz, Stéphane Udry
. To date, more than 20 extra-solar giant planets have been found using high-precision radial-velocity techniques. In June 1998 we started a long-term extra-solar planet-search programme using the...

. A new extra-solar planet has been discovered in the context of the CORALIE survey at La Silla Observatory. This planet orbits the star HD 192263. In this paper we present and discuss the basic...
A "diamond-ring" star: the unusual morphologic structure of a young (multiple?) object (2007)
Yun, Joao L., Torrelles, Jose M., Santos, Nuno C.
We have observed IRAS06468-0325 obtaining optical and infrared images through IJHKs and L' filters, K-band low-resolution spectroscopy, together with millimetre line observations of CO and CS....

The HARPS high-resolution high-accuracy spectrograph is offered to the astronomical community since the second half of 2003. Since then, we have been using this instrument for monitoring radial...

Nine extrasolar planets with masses between 110 and 430M are known to transit their star. The knowledge of their masses and radii allows an estimate of their composition, but uncertainties on...

Aims: The primary motivation for this project is to search for metal-rich star forming regions, in which, stars of super-solar metallicity will be created, as hopefully, will be extra-solar planets...
Fernandes, Joao, Santos, Nuno C.
In this paper we analyse and discuss the HR Diagram position of two extra-solar planet-host stars - HD37124 and HD46375 - by means of theoretical stellar evolution models. This work was triggered by...
Lipossomas: a bala mágica acertou? (2002)
Efficient drug delivery systems are as important as drug themselves. A powerful drug unable to reach the target cell is useless in practice. Ehrlich's Magic Bullet was the first carrier system to be...
Confirming the Metal-Rich Nature of Stars with Giant Planets (2001)
Santos, Nuno C., Israelian, Garik, Mayor, Michel
With the goal of confirming the metallicity ``excess'' observed in stars with planetary mass companions, we have conducted a high-precision spectroscopic study of a ``comparison'' sample of dwarfs...

Partition of the intrinsically fluorescent HIV fusion inhibitor enfuvirtide into lipidic membranes is relatively high (Delta G =6.6 kcal x mol(-1)) and modulated by cholesterol. A shallow position in...

Santiago, Patrícia S., Moura, Franciane, Moreira, Leonardo M., Domingues, Marco M., Santos, Nuno C., Tabak, Marcel
The extracellular hemoglobin of Glossoscolex paulistus (HbGp) is constituted of subunits containing heme groups, monomers and trimers, and nonheme structures, called linkers, and the whole protein...
