Characterizing the smallest planet hosts


Principal investigator
Elisa Delgado Mena

The determination of accurate and precise stellar parameters and chemical abundances of M dwarfs is of prime importance to study the Galactic chemical evolution since they are the most abundant in the Galaxy. Moreover, M dwarfs are excellent targets for the search of small planets due to their lower mass. However, to characterize the mass, radius and bulk composition of a planet we need to have the more  precise parameters and chemical composition of its host star. The goal of this project is to better characterize this population of poorly known stars in order to achieve the previous issues by using high resolution NIR spectra.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
