Lines of Research

 

1. FUNDAMENTAL ASTRONOMY

This field consists of spatially locating Solar System bodies, stars and extragalactic objects. The Abrahão de Moraes Observatory (Valinhos, SP) meridian telescope CCD carries out a variety of programs with movements of its own using photometry.

2. PLANETARY SYSTEM DYNAMICS AND CELESTIAL MECHANICS

This project aims to study planetary, satellite, Solar System and extraterrestrial planetary system dynamics. Studies on the origins of features observed in the Solar System are scientific interests of this field, in addition to Chaos, Resonance, Stationary Solutions and Coherent Motion.

Celestial Mechanics comprises modern mechanics applications to celestial phenomena. This area of research also focuses on developing fundamental mathematical theories on Celestial Mechanics.

3. STELLAR ASTROPHYSICS


This major area of study is currently not sub-classified in Capes/CNPq, therefore it is wide-ranging and encompasses: star formation, X-ray binaries, supernovae, gamma ray bursts, cataclysmic variables, stellar evolution, stellar halo populations, disk and bulge of the Milky Way and other galaxies, star clusters, pre-main sequence stars, cool and warm stars, neutron stars, black holes, stellar jets and winds and gravitational waves.

4. GALAXY CLUSTERS

The majority of work on galaxies aims to analyze those galaxies belonging to clusters. This occurs mainly due to the fact that they are relatively at the same distance, leading to a higher reliability in studies involving properties of greater samples of galaxies. Interactions of cluster galaxies and intra-cluster gas related questions are also studied.

5. GALAXIES


Normal and active galaxies are investigated. Normal galaxies studies comprehend: our galaxy structure, elliptical and lenticular galaxies with the presence of rectangular bulges and bars, chemical evolution models and stellar population. Researchers aim to study spiral structures and their bulges, active cores on galaxies in terms of their emission lines, as well as formation mechanisms involving accretion disks and supermassive black holes and their correlation with extragalactic jets.

Formation of Broad-line regions is also studied and the variability of active cores in galaxies (or quasars) is monitored.

6. COSMOLOGY

 

Study of the Universe’s first structures formation, magnetic field effects on the primordial universe, galaxy formation and determination of cosmological parameters.

7. INTERSTELLAR MEDIUM

 

The study of interstellar matter in the Galaxy and other stellar systems, extended envelopes and implications in the galactic structure. Study of photoionized nebulae, central stars in the context of galaxy structure and evolution, and implications in these systems chemical evolution. Phenomena responsible for  the dynamic evolution of galaxies interstellar medium are also studied, such as: formation and destruction of clouds, shock waves, turbulence and cosmic rays.

8. SOLAR SYSTEM ASTROPHYSICS

 

Study of solar atmosphere, planets and satellites, and comets phenomena. Researches focus primarily on the study of local and global properties of the solar corona and the sun’s magnetic field evolution. Comet researches essentially focus on astrochemistry, photometry (visible and infrared) and morphology.

9. RADIO ASTRONOMY


Studies of extragalactic sources and molecular lines using the 13.7m radio telescope in Atibaia and the submillimetre telescope SEST(Chile). Development of instrumentation for radio astronomy.

10. INSTRUMENTATION

Instrumentation and development for Astronomy, whether optical, infrared or radio astronomy. The SOAR telescope is of great motivation for instrument development, since the department is involved with the construction of two spectrographs.

11. EXOPLANETS AND ASTROBIOLOGY


Study of planets outside the solar system. Discovery of new planets using observatories. Description of stars with planets (fundamental physical parameters, chemical composition, stellar activity). Study of the relationship between planets and stars for better understanding of planetary systems formation.

Astrobiology covers the origin, evolution, distribution and future of life in the Universe.
