Impact cratering is a physical process causing geological changes on all planetary surfaces. It is one of common processes responsible for crustal structure and evolution over geological timescales. High-fidelity shock physics simulations are made to track the fate of a planetary impactor and associated shock changes in the target material during a non-catastrophic impact event. The size of...
The Sun exists at the intersection of many scientific frontiers, where classical and modern physics converge with environmental science, engineering, and data analytics. This paper presents a novel interdisciplinary approach to solar physics, emphasizing how understanding the Sun requires crossing traditional disciplinary boundaries. We explore the fusion-driven processes at the core, the...
The use of photonic alternatives to conventional optical trains in telescope instrumentation offers key advantages in satisfying near-impossible tasks demanded by astrophysics (such as imaging Earth-sized exoplanets within the habitable zone of their host star or their formation within a proto-planetary disc).
Current imaging instruments using adaptive optics account for atmospheric seeing...
We present a new catalog for solar flares derived from Geostationary Operational Environmental Satellite (GOES) data using a deep learning–based detection method. Unlike the conventional rule-based methods, our approach identifies flare rises directly from the time series with a model that integrates multi-scale convolutional layers, a bidirectional long short-term memory (BiLSTM), and...
Despite the large quantity of observational data available, the Sun’s magnetic field dynamics remain a mystery. Solar flares and eruptions, which result from the field evolution, can have significant impacts on Earth and our space environment. Data-driven modelling of the solar magnetic field uses photospheric observations as boundary conditions to drive a simulation of the field above the...
Lightsails are an enticing proposal for spacecraft that can travel to nearby star systems such as Alpha Centauri. Their advantage is their ability to reach speeds up to $0.2c$ when accelerated by high-power lasers. One significant obstacle to lightsail missions is that the sail experiences perturbations (e.g. from laser-beam noise or atmospheric effects) that act to eject the sail from the...
