- Description: Topic: Study of Interplanetary Optimization between Earth and Mars
Location: SENG -201
Abstract:
Astrodynamics-based trajectory planning, and optimization are vital in deep space exploration mission design. Interplanetary Trajectories are the orbital paths that a spacecraft takes between a starting and destination celestial body at a certain point in time. Maximum final mass and minimal travel time are two primary parameters that are always targeted to be optimized in Interplanetary trajectory. We focused on the time aspect in our study as it is very crucial when planning any interplanetary space trip. The track between Earth and Mars from 2020 to 2050 is shown using a trajectory optimization tool. The trajectory optimization tool is based on a genetic algorithm and determines trajectories using a patched conics approximation. Time of Flight (TOF), Departure C3 energy, Arrival Velocity, and the orbital elements of the proposed orbit are the tool's output parameters. To select an orbit for Earth to Mars, we focused on getting TOF, C3 Energy, and arrival velocity in the acceptable range. Further, we utilized two open-source libraries, Pykep and PyGMO, to validate the findings achieved using the optimization tool. The outcomes were the journey time, Arrival Vinf, Departure Vinf and Insertion DV. The two approaches were evaluated in terms of trajectory view and travel time. Between the two methods, there is a significant difference in travel duration observed. The best ideal year between 2020 and 2050 will be chosen after comparing the results of the trajectory plotted and TOF obtained from the optimization tool and Pykep library used.

- Description: Topic: Assessing the Dynamically Driven Double-Degenerate Double-Detonation (D6) Progenitor Model for Type Ia Supernovae: A Comparison of Dynamic and Adaptive Mesh Simulations
Location: SENG 201
Abstract:
Type Ia supernovae (SNe Ia) play a crucial role in deciphering cosmological phenomena, including the accelerated expansion of the universe. Despite their significance, the driving mechanisms behind SNe Ia are yet to be fully confirmed. The dynamically driven double-degenerate double-detonation (D6) scenario has gained traction as the most likely explanation for nine hypervelocity galactic white dwarfs discovered by the ESA Gaia space mission. In this thesis, I will present a comparative analysis of hydrodynamical simulations of D6 SNe Ia using two leading hydrodynamical simulation frameworks: AREPO, which utilizes an unstructured, Voronoi tessellation dynamic moving mesh, and FLASH, with its structured adaptive Eulerian mesh. I will briefly describe the impact of our findings on the physical processes which give rise to SNe Ia.

- Description: Topic: 3D Hydrodynamical Simulations of Merging One-CO White Dwarf Binaries
Location: SENG 201
Abstract:
In 1181, "a guest star", as bright as the planet Saturn was observed in the sky by Chinese and Japanese astronomers. A recent study has identified the star IRAS 00500 + 6713 as the remnant from the 1181 event, surrounded by the nebula "PA 30" and pointing to an unusual scenario where the explosion could have been caused by the merger of two white dwarfs. In this thesis, I will present a 3D hydrodynamical simulation model for SNe Iax in the context of the double-degenerate channel of merging ONe- CO white dwarf binary using the adaptive mesh refinement hydrodynamics code FLASH. I will discuss the explosion mechanism, the characteristics of the remnant, and other implications of this model.
