POWER OF MATHS. “Calculated values of Heintzmann constants for different star models.” A lovely example of where mathematical deductions based on sophisticated modeling has led to actual measurement predictions for a variety of dense matter stars, and then compared some of those calculated values with actual measured values. https://www.sciencedirect.com/science/article/pii/S0577907319309773 View in LinkedIn

DERIVED DATA. “We examine the viability of metric potentials and investigate the effective energy density, effective radial and transverse pressure components, anisotropic parameter, mass-radius relation, energy conditions and stability for different values of the coupling parameter.” https://www.sciencedirect.com/science/article/pii/S0577907319309773 View in LinkedIn

AGREEMENT OF MATHS AND OBSERVATION. “Using the observed values of masses of considered stars in modified TOV equation, we have evaluated the values of radii, compactness parameter and gravitational redshift for B = 64 MeV/fm3 which are very close to the values obtained in literature corresponding to the different choices of bag constant.” https://www.sciencedirect.com/science/article/pii/S0577907319309773 View in LinkedIn

“Metallic Helium at Extreme Density Inside Giant Planets and White Dwarf Stars. The goal of our project was to develop a new experimental approach to enable the measurement of the insulator-to-metal transition in warm dense fluid helium for modeling the interiors of giant planets and dwarf stars.” (2018) https://lnkd.in/dtAti2a View in LinkedIn

HI-DENSITY MATTER. “Despite the considerable efforts of researchers in the fields of condensed matter physics, astrophysics, plasma physics, high-energy-density (HED) science, and inertial confinement fusion research, the equation of state and the transport properties of low-Z systems are poorly understood.” https://lnkd.in/dtAti2a View in LinkedIn

CRITICAL KNOWLEDGE. “An accurate description of the transition from the condensed-matter regime to the warm-dense-matter regime is particularly difficult, yet it is critical to improving our understanding of planetary and stellar formation and evolution.” https://lnkd.in/dtAti2a View in LinkedIn

THE CODE. “What is the algorithm running on the laptop of the Universe? If such an algorithm exists, I would argue that it should be a simple one defined on the discrete spacetime lattice. The complexity and richness of the Universe come from the enormous memory size and CPU power of the laptop, but the algorithm itself could be simple." https://lnkd.in/dZi_jmp View in LinkedIn

THE SIMPLEST UNKNOWNS. “In the wake of the tremendous amount of data collected by NASA's Juno and Cassini probes at Jupiter and Saturn, the need increases for accurate models of the physical and chemical properties of gas-giant constituents such as hydrogen isotopes, helium, and their mixtures.” https://lnkd.in/dtAti2a View in LinkedIn
