"For example, there are small traces of hydrogen in Mars' core. "It's like a puzzle in some ways," Lekic said. And the team thinks that the interior of the planet and the bombardment of space rocks across its surface may have played a key role in this evolution. The researchers think that Mars may have gradually evolved into the planet we see today transforming from a habitable environment to one hostile to life. Traces of magnetism in the crust of Mars indicates that the Red Planet did once have this magnetic shielding that would have protected the complex molecules needed for life from harsh solar radiation that would break them apart. Mars' core does not generate this protective shield, and so the planet's surface conditions are hostile to life." "The uniqueness of Earth's core allows it to generate a magnetic field that protects us from solar winds, allowing us to keep water. The end result of the formation and evolution processes can be either the generation or absence of life-sustaining conditions," UMD Associate Professor of Geology and research author, Nicholas Schmerr, explained. "You can think of it this way the properties of a planet's core can serve as a summary about how the planet formed and how it evolved dynamically over time. This could indicate that the two neighboring planets experienced different formation conditions. Earth's core has a much lower percentage of light elements implying that the core of Mars is much less dense than the core of our own planet. The team was also able to determine some of the chemical elements that compose the Martian core finding evidence of a surprisingly large proportion of light elements such as sulfur and oxygen in its innermost layer. The University of Valencia is an equal opportunity employer that is committed to diversity and inclusion encouraging applications from women and/or other underrepresented groups.The team managed to unearth a high proportion of sulfur and oxygen and other light elements in the innermost layer. We aim to fill the positions as soon as possible. Please also include the contact details of two potential referees. The successful candidates are expected to start their PhD on September 16, 2023, and have the master degree by the time the appointment starts.Īpplicants should send a CV, a brief statement of research interests, and academic transcripts, before May 5th 2023, to Toni Font (j.) and Milton Ruiz (). Eligible candidates must have obtained their degree after January 1st 2018. These positions are open to candidates holding a bachelor degree in physics issued by a non-European Union University or institution. We are seeking highly motivated candidates interested in developing tools and algorithms to characterize gravitational-wave sources based on current observations as well as in improving numerical techniques to perform accurate long-term simulations involving compact objects, such as black holes, neutron stars, boson stars and other exotic compact objects, to tackle challenging open issues in theoretical astrophysics, numerical relativity and fundamental physics. The group is part of the LIGO-Virgo-KAGRA Collaboration, the Einstein Telescope Collaboration and of the LISA Consortium. The group comprises faculty members Pablo Cerda-Duran, Isabel Cordero-Carrion, Jose Antonio Font and Alejandro Torres-Forne, non-tenured faculty members Milton Ruiz and Nicolas Sanchis-Gual, postdoc Raimon Luna, and eight PhD students. The focus of the research will be on numerical-relativity simulations of binary neutron star mergers, exotic compact objects and fundamental fields, along with gravitational-wave modelling, searches and data analysis. The Relativistic Astrophysics Group at the University of Valencia (Spain) invites applications for two 4-year PhD positions in the areas of Gravitational-Wave Physics and Relativistic Astrophysics.
