Astrophysics is an area concerning various physical ranging from planetary sized systems, to galactic scale systems and beyond, that intersects various disciplines such as Newtonian dynamics, relativistic physics and particle physics processes.
For our latest developments/activities in this area, please see the listing below at the end of this article.
An exoplanet is a planet outside the Solar System. In the Milky Way galaxy, it is expected that there are many billions of planets (at least one planet, on average, orbiting around each star, resulting in 100–400 billion exoplanets), with many more free-floating planetary-mass bodies orbiting the galaxy directly.
We study the long-term dynamics of known multi-planet systems. This allow us to test the accuracy of the orbital parameters' determinations, as well as to understand how these systems evolved. We also look for the stable zones in the gaps between already-known planets in order to determine where is it possible to locate Earth-like planets.
See here a movie made by the PhD Animation on "Exoplanets Explained", for a review on the main observational methods used to detect exoplanets.
Zeus Sales Moreira successfully defended his Ph.D. thesis on March 31st 2025, which was advised by C. Herdeiro. The committee was composed by Profs. Darío Nunez, Eugen Radu, Alberto Saa and Gonzalmo Olmo and unanimously praised the excellent work of the candidate. Congratulations Zeus and all the best for the future!
Black holes are the most massive objects in the Universe and provide an ideal testing ground for gravity in the strong field regime.
The NewFunFiCO mid term meeting took place online on March 20 bringing together many consortium members, to share their experiences with the REA.
One of the most efficient energy sources in the universe is the matter accretion onto compact objects, such as black holes (BHs) and neutron stars (NSs). Since magnetic fields are ubiquitous everywhere, the accretion flow is expected to be magnetized in nature, where the large-scale magnetic fields inside the disks are commonly rooted either from the companion star or the interstellar medium.
A meeting of the NewFunFiCO network will take place in Valencia, from 20-22 May 2025. More information can be found here.
