Comprehensive analysis of solar plasma ejections

Researchers from the Institute of Theoretical and Experimental Astronomy (IATE), together with an international team, published an article in which, based on observations, the deviations of solar material ejections are studied.

Galactic migrations: How are clusters populated?

José Benavides, a doctoral fellow at the Institute for Theoretical and Experimental Astronomy (IATE), Mario Abadi, a researcher at the same institute, and Laura Sales, from the University of California, published an article in which they analyze, based on computer simulations, how the galaxies arrive to clusters and what their interactions are like once they are inside.

Waiting for the first contact

Marcelo Lares, researcher at IATE (CONICET - UNC), in collaboration with José Funes (CONICET - Universidad Católica de Córdoba) and Luciana Gramajo (CONICET - Observatorio Astronómico de Córdoba), developed and simulated a model that allows analyzing the probability of contacts between civilizations that are in different points of our galaxy.

Planetary Systems

The research interests of the Group of Planetary Systems focus on the origin and dynamic evolution of planets and small bodies around the Sun and other stars. Since the discovery of the first extrasolar planet in 1995 by Michel Mayor and Didier Queloz, we have witnessed a true revolution in planetary astronomy with several thousand of new systems detected so far. While some of their features are similar to our Solar system, others show marked differences, including planetary bodies in cometary and/or retrograde orbits, hot Jupiters and planets in multiple star systems. This enormous and growing diversity points towards planetary formation processes which may be much more complex than imagined a few years ago.

Our work is developed in unison with staff from the Astronomical Observatory of the UNC. Current research topics include:

  • Formation and orbital evolution of planets in binary star systems.
  • Models of tidal interaction and its application to planets and satellites.
  • Secular and resonant evolution of multiple planetary systems.
  • Resonant dynamics of satellites around gas giants.
  • Study of coorbital configurations around planets or stars.
  • Study of coorbital configurations around planets or stars.

In collaboration with colleagues from FaMAF, FCEFyN and researchers from other universities, we have recently undertaken studies on the dynamics of artificial satellites in LEO and MEO regions, searching for optimal de-orbiting mechanisms with minimum fuel consumption. We aim to develop dynamical algorithms that may help design future space missions complying with environmental and sustainability constraints.
