The works to be developed in this project represent at the same time a continuation and an enlargement of what our team has been accomplished for a while. This includes, in addition to the scientific works, the cooperation and experiences in possible new directions imposed by the current reality concerning the quantity and quality of the observational data as well as the science itself.Ou…
Astrometry is a fundamental field of research in Astronomy, being the base for almost all other areas in this science. On the last few years our group has undertaken the effort to modernize and direct the researches in Astronometry at IAG/USP, for the study of targets of special interest through precise astrometric catalogues (i.e. PM2000, Hipparcos) and by observations made with the Meri…
We propose to search the whole sky to find the common proper motion (CPM) stars brighter than V~16.0 mag. For this purpose, we will first find the CPM stars in the very accurate astrometric catalogue PPMX. Afterwards, we will perform data mining in two additional databases: *The proper motion catalogue in the low-extinction regions toward the galactic bulge, based only on CCD meridian obs…

Gravitational lenses are fundamental structures in several domains in the study of the Universe: dark matter, Hubble constant, mass distribution in deflecting galaxies, etc. However, these structures are rare and the only a small number of them are known and "measured". This small number imposes sever limits on the horizon of possibilities for scientific studies of these structures. 7-8 y…
This project aims to insert the student in an interesting and relevant subject that is star formation. It uses the experience of involved researchers and, especially, the new reality of observational data dictated by the second release of Gaia space mission, complemented with others from literature. The focus is the Chamaeleon molecular cloud complex and its star formation history. Within…
This IC work is part of a broader effort to search for gravitational lensing in the first Gaia data release - GDR1 and eventually in the second one, GDR2. The objective of this IC is to contribute with the work that has been developed by the GraL (Gaia Gravitational Lensing) group, formed by colleagues from various institutions and countries: Bordeaux, Heildelberg, Liège, Lisboa, Nice and…
To reliably determine the main physical parameters (mass and age) of young stars we must know their distance. A precise determination of masses and ages is required to constrain the disk lifetime and can provide indications about the timescale of planet formation. While the average distance to nearby star-forming regions (< 200 pc) is often known, the distances to individual stars are usu…

Since 2016, the European Space Agency (ESA) and the Gaia Data Processing Analysis Consortium (Gaia DPAC) release worldwide and at the same time approximately every 2 years, a huge amount of observational data of the highest quality. DR3 delivered the astrometry and photometry of almost 2 billion objects, including more than 1.8 million quasars. With the aim of producing a unique and stati…
In April 2018 the European Spatial Agency (ESA) and the Gaia Data Processing Analysis Consortium (DPAC), published the second Gaia Data Release (GDR2) with the complete astrometry and Gaia photometry for plus than one billion objects, among them 550 thousand known quasars. These data were obtained after 22 months of observations performed by the satellite since July 2014. Aiming to explor…
