Portuguese Involvement with the European Southern Observatory
As per 1.10.2012
Portugal joined the European Southern Observatory (ESO) in June 2000 and the membership was ratified by the Portuguese Parliament in May 2001.
Contracts totally about 1.4 million euro have been awarded to Portuguese industry since it joined the organisation. This does not include Portuguese companies that may have acted as sub-contractors when the prime contractors were in a different country.
Discoveries by Portuguese astronomers using ESO telescopes
N. C. Santos (Centro de Astrofísica da Universidade do Porto, Portugal and Departamento de Física de Astronomia, Faculdade de Ciências da Universidade do Porto, Portugal), contributed to the discovery of 50 new exoplanets with HARPS. eso1134
N. C. Santos (Universidade do Porto, Portugal), A. Correia (Universidade de Aveiro, Portugal) contributed to the discovery of the richest planetary system to date: the sun-like star HD 10180 has at least 5 planets, with evidences of 2 additional ones. eso1035
A. Amorim, J. Lima, F. D. Santos, and A. Moitinho (SIM-IDL, University of Lisbon, Portugal), R. Marques and J. Pinhão (University of Coimbra, Portugal), and J. Rebordão (INETI, Amadora, Portugal) contributed to a study of the giant galaxy Centaurus A, which reveals it has recently captured and digested a smaller spiral galaxy. eso0944
Nuno Santos and Sergio Sousa (Centro de Astrofisica, Universidade de Porto, Portugal) contributed to a census of 500 stars, 70 of which are known to host planets. This census, performed with HARPS, suggests that planet-hosting stars would have destroyed their lithium more efficiently than planet-free stars. eso0942
Michaël Bazot (University of Porto, Portugal) and a team of astronomer realized that the star iota Horlogii have drifted away from the Hyades cluster. This discovery has implications on the theories of star and planet formation, as well as for the dynamics of our Milky Way. eso0809
Xavier Bonfils (Lisbon Observatory) contributed to the discovery of the first earth-like planet in the habitable zone of another star. This super-earth is only 5 times the mas off the Earth, and orbit a red dwarf star, already known to harbour a Neptune-mass planet. eso0722
Nuria Huelamo (ESO and University of Lisboa) contributed to the discovery that objects only a few times more massive than Jupiter are born with discs of dust and gas, i.e. the raw material for making planets. This suggests that miniature versions of the solar system may circle objects that are some 100 times less massive than our sun. eso0619
Nuno C. Santos (Observatoire de l'Université de Genève, Switzerland, Centro de Astronomia e Astrofisica da Universidade de Lisboa and Centro de Geofisica de Evora, Portugal), Alexandre C. M. Correia (Universidade de Aveiro, Portugal), contributed to the discovery and study of an exo-planetary system composed of three Neptune-mass planets, using HARPS. It also appears that the planetary system contains an asteroid belt. eso0618
Nuno Santos, of the Lisbon Astronomical Observatory, contributed to accurately determine the radius and mass of the smallest core-burning star known until now. The star is 96 times heavier than planet Jupiter but only 16% larger. It is the first time that direct observations demonstrate that stars less massive than 1/10th of the solar mass are of nearly the same size as giant planets. eso0507
Nuno Santos, of the Lisbon Astronomical Observatory, contributed to the discovery of the smallest ever extra-solar planet, using HARPS. The planet has only 14 times the mass of the Earth. eso0427
Nuno Santos, of the Lisbon Astronomical Observatory, contributed to the discovery and study of two extra-solar planets.. They belong to the OGLE transit candidate objects and could be characterized in detail. These were the 2d and 3rd exoplanets discovered using that method. eso0415
ISAAC dataset on Orion’s Trapezium - The data also form part of the collaborative research being undertaken by the European Commission-sponsored Research Training Network on "The Formation and Evolution of Young Star Clusters" (RTN1-1999-00436), led by the Astrophysical Institute Potsdam, and including the Arcetri Observatory in Florence (Italy), the University of Cambridge (UK), the University of Cardiff (UK), the University of Grenoble (France), the University of Lisbon (Portugal) and the CEA Saclay (France). eso0104
ESO science press releases from 2011 that have involved Portuguese astronomers and astronomers working at Portuguese institutes include:
- VISTA Finds 96 Star Clusters Hidden Behind Dust
- Fifty New Exoplanets Discovered by HARPS
- Many Billions of Rocky Planets in the Habitable Zones around Red Dwarfs in the Milky Way
Number of Portuguese astronomers and staff working at ESO
As of September 2012 there are 8 Portuguese nationals employed at ESO. Seven in Garching and one at Paranal in Chile.
