The EXO-UV program: lastest advances of experimental studies to investigate the biological impact of UV radiation on exoplanets
Ximena C. Abrevaya, Petra Odert, Oscar J. Oppezzo +4
The EXO-UV program is an international, interdisciplinary collaboration between astrophysicists and biologists aimed at expanding the characterization of ultraviolet radiation (UVR…
Protective Effects of Halite to Vacuum and Vacuum-Ultraviolet Radiation: A Potential Scenario During a Young Sun Superflare
Ximena C. Abrevaya, Douglas Galante, Paula M. Tribelli +16
Halite (NaCl mineral) has exhibited the potential to preserve microorganisms for millions of years on Earth. This mineral was also identified on Mars and in meteorites. In this stu…
Breve historia de la astrobiología en Argentina
Ximena C. Abrevaya
Astrobiology or exobiology is a relatively new area of science that investigates the possibilities of finding life in other places in the universe. This not only includes the explo…
The UV surface habitability of Proxima b: first experiments revealing probable life survival to stellar flares
Ximena C. Abrevaya, Martin Leitzinger, Oscar oppezzo +5
We use a new interdisciplinary approach to study the UV surface habitability of Proxima under quiescent and flaring stellar conditions. We assumed planetary atmospheric composi…
Radiation as a Constraint for Life in the Universe
Ximena C. Abrevaya, Brian C. Thomas
In this chapter, we present an overview of sources of biologically relevant astrophysical radiation and effects of that radiation on organisms and their habitats. We consider both…
A Simple Laser-Based Device for Simultaneous Microbial Culture and Absorbance Measurement
X. C. Abrevaya, E. Cortón, O. Areso +1
In this work we present a device specifically designed to study microbial growth with several applications related to environmental microbiology and other areas of research as astr…
"Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments"
Claudia Lage, Gabriel Dalmaso, Lia Teixeira +8
The results obtained in these experiments have revealed a remarkable resistance of extremophilic bacteria and archaea against different radiation sources (VUV, solar wind simulants…
Comparative Survival Analysis of Deinococcus Radiodurans and the Haloarchaea Natrialba Magadii and Haloferax Volcanii, Exposed to Vacuum Ultraviolet Irradiation
Ximena C. Abrevaya, Ivan G. Paulino-Lima, Douglas Galante +4
The haloarchaea Natrialba magadii and Haloferax volcanii, as well as the radiation-resistant bacterium Deinococcus radiodurans, were exposed to vacuum-UV (V-UV) radiation at the Br…
Archaea-based Microbial Fuel Cell Operating at High Ionic Strength Conditions
Ximena C. Abrevaya, N. J. Saco, P. J. D. Mauas +1
In this work two archaea microorganisms (Haloferax volcanii and Natrialba magadii) used as biocatalyst at a microbial fuel cell (MFC) anode were evaluated. Both archaea are able to…
Long-term chromospheric activity in southern M dwarfs: Gl 229 A and Gl 752 A
Andrea P. Buccino, Rodrigo F. Díaz, María Luisa Luoni +2
Several late-type stars present activity cycles similar to that of the Sun. However, these cycles have been mostly studied in F to K stars. Due to their small intrinsic brightness,…
Microbial Fuel Cells Applied to the Metabolically-Based Detection of Extraterrestrial Life
Ximena C. Abrevaya, Pablo J. D. Mauas, Eduardo Cortón
Since the 1970's, when the Viking spacecrafts carried out experiments aimed to the detection of microbial metabolism on the surface of Mars, the search for nonspecific methods to d…
