The Galactic Phosphorus Survey. I. Chemical Evolution across the Galactic Disk from 750 FGK Stars
Dionysios Gakis, Keith Hawkins, Zachary G. Maas +5
Phosphorus (P) is an odd- element produced primarily in massive stars and is also important for planetary chemistry as an element essential to life. However, its evolution over…
Echoes of Star Stories: Integrating Indigenous narratives into modern stellar astrophysics
Dionysios Gakis
Indigenous narratives have long preserved observations of celestial phenomena, offering insights that resonate with modern astrophysical research. Deeply embedded in cultural tradi…
Revisiting thermoelectric effects in the crust of neutron stars
Dionysios Gakis, Konstantinos N. Gourgouliatos
Context. Large thermal variations have been observed in neutron stars that typically are not aligned with density gradients. Such terms may activate the Biermann battery effect, le…
Orbital analysis of the Pluto-Charon moon system's mutual interactions and forced frequencies
Dionysios Gakis, Konstantinos N. Gourgouliatos
Context. The orbits of the four small moons in the Pluto-Charon system, Styx, Nix, Kerberos and Hydra, are circumbinary, as the former form a binary dwarf planet. Consequently, the…
Orbits of the TOI-1338 and TIC-172900988 systems
Dionysios Gakis, Konstantinos N. Gourgouliatos
Recent observations by TESS revealed the existence of circumbinary planets in the systems of TOI-1338 and TIC-172900988. The purpose of this work is to model the planetary orbits i…
Radiation protection and shielding materials for crewed missions on the surface of Mars
Dionysios Gakis, Dimitra Atri
A potential crewed mission to Mars would require us to solve a number of problems, including how to protect astronauts against the devastating effects of energetic charged particle…
Crewed Missions to Mars: Modeling the Impact of Astrophysical Charged Particles on Astronauts and Their Health
Dimitra Atri, Caitlin MacArthur, Sriram Devata +8
The impact of exposure to astrophysical ionizing radiation on astronaut health is one of the main concerns in planning crewed missions to Mars. Astronauts will be exposed to energe…
Modeling the effectiveness of radiation shielding materials for astronaut protection on Mars
Dionysios Gakis, Dimitra Atri
The surface of Mars is bombarded by energetic charged particles of solar and cosmic origin with little shielding compared to Earth. As space agencies are planning for crewed missio…
Orbit determination of the moons of the Pluto-Charon system
Dionysios Gakis, Konstantinos N. Gourgouliatos
Four small moons (Styx, Nix, Kerberos and Hydra) are at present known to orbit around the barycenter of Pluto and Charon, which are themselves considered a binary dwarf-planet due…
