17. TOI-1811: Unveiling a Low-Mass Companion to a Hot Jupiter Through Transit Timing

Talk

The formation and migration of hot Jupiters remain open questions in exoplanetary science. Their predominantly isolated architecture provides few direct clues about the dynamical processes responsible for placing giant planets on short-period orbits. Systems in which a hot Jupiter retains a close planetary companion are therefore particularly valuable, as gravitational interactions within such...

30. Understand the Geodynamic Drivers and Magmatic Mechanisms of L 98-59 d through Comparative Analysis with Venus and Jupiter’s Moon Io.

Talk

L98-59 is an M-dwarf star located about 34.6 light-years away from Earth in the constellation Volans. L98-59 d is an extreme super-Earth exoplanet initially discovered by NASA's TESS in 2019. The JWST and ground-based facilities confirmed it belongs to an entirely new class of molten, sulphur-rich planets.
Volcanism is a critical planetary process that sheds light on internal structure,...

29. A Computational Model to Generate Artificial L4/L5 Equilibrium States via Auxiliary Mass Systems in the Jovian Circular Restricted Three-Body Problem to Investigate Europa

Talk

This research developed a model using a modified CR3BP framework with an additional artificial mass to locate and optimise artificial Lagrange points (L4/L5) in the Jupiter-Europa system, positioning a satellite to investigate Europa. The model evaluates potential system configurations across a parameterised grid of source positions (xA, yA) and the mass ratio of the Artificial mass to the...

20. Surface Heating and Melting of Icy Satellites During Accretion

Talk

Icy satellites form by accreting ice-rich planetesimals within the circumplanetary disk of their host planet. Under short accretion timescales, the resulting impact energy can vaporize surface ices, generating a transient water-vapor atmosphere. We present preliminary results of numerical simulations performed to study the heating, melting, and ice-rock separation at the surface of these...

32. Early Thermal Evolution of Psyche

Sumit Sankhyan (Maharishi Markandeshwar (Deemed to be University), Mullana, Haryana (India))

Talk

The study of thermal evolution is important for understanding the initial phases of differentiation and formation of metal rich bodies such as 16-Psyche. In this model we analysis the heat generation and thermal evolution of proto-psyche in early phases. This study includes the contribution of short lived radionuclides 26Al and 60Fe, as a significant heat source in early evolution. In addition...

24. Low-Thrust Accessibility of Near-Earth Object Associations for Multi-Target Missions

Arkadiusz Hess (Uniwersytet Warszawski)

23/10/2026, 11:20

Talk

Orbital associations of Near-Earth Objects (NEOs) can be used to identify groups with similar low-thrust mission accessibility. We present a computational pipeline that links the search for orbital associations with preliminary multi-target mission design. Candidate NEO pairs are first identified using a $k$-nearest-neighbour search based on a KD-tree and then evaluated using the Drummond...

13. A Scenario-Based Model for Preparedness and Response to Extraterrestrial Natural Hazards in Central Iran: A Case Study of Asteroid and Meteorite Impacts

Saeed Givehchi (Faculty of Environment, University of Tehran)

23/10/2026, 11:35

Talk

Extraterrestrial natural hazards, particularly the impact of asteroids, meteorites, and other celestial bodies on Earth, are low-probability events with potentially severe and cascading consequences. Despite their potential impacts, these hazards have received limited attention in Iran’s disaster risk management and preparedness planning. This study focuses on Central Iran and proposes a...
