Universidade de São Paulo (USP). Instituto de Astronomia, Geofísica e Ciências Atmosféricas (IAG) (Institutional affiliation for the last research proposal) Birthplace: Brazil
I am Bachelor in Molecular Sciences (2005) at University of São Paulo, Brazil. I also have the Master (2008) and Ph.D. (2012) degrees in Astrophysics at Institute of Astronomy, Geophysics and Atmospheric Sciences of University of São Paulo. During the Ph.D. I spend one year at Kapteyn Astronomical Institute in Groningen, The Netherlands. My main research field is High Energy Astrophysics (X-rays) and Physics and Astrophysics of Compact Objects. In parallel, I do some research in Astrobiology. (Source: Lattes Curriculum)

- Compact stars in binaries: investigating the composition of superdense matter, BP.PD
Abstract
Neutron stars are extreme objects in the universe. Their birth is marked by the death of a star with mass between 8 and 25 solar masses in a cataclysmic explosive event, releasing 10^53 erg of energy and can suppress the brightness of an entire galaxy. After the contraction of the iron core of the progenitor, the remnant is a neutron star with 1.4 solar masses and 10 km of radius, which...
- Modelling the quasi-periodic oscillations and their respective time lags in neutron star low-mass X-ray binaries - the NS-LMXB 4U 1636-53 as a case study, BE.EP.PD
Abstract
The main goal of this research project is to achieve expertise in numerical methods to study and simulate in full general relativity high-energy astrophysical phenomena relative to neutron stars in X-ray binary systems. This will lead to a better understanding of the accretion flows onto the compact star and potentially, a new way to constrain its properties and to learn about its equat...
