Helioseismological Implications of Recent Solar Abundance Determinations

, 2004
We show that standard solar models are in good agreement with the helioseismologically determined sound speed and density as a function of solar radius, the depth of the convective zone, and the surface helium abundance, as long as those models do not ...

Monte Carlo Radiation Transport for Astrophysical Transients Powered by Circumstellar Interaction

The Astrophysical Journal, 2023
In this paper, we introduce SuperLite , an open-source Monte Carlo radiation transport code designed to produce synthetic spectra for astrophysical transient phenomena affected by circumstellar interaction. SuperLite utilizes Monte Carlo methods for semi-

Study of sdO models. Pulsation Analysis

, 2009
We have explored the possibility of driving pulsation modes in models of sdO stars in which the effects of element diffusion, gravitational settling and radiative levitation have been neglected so that the distribution of iron-peak elements remains ...

Emission from Very Small Grains and PAH Molecules in Monte Carlo Radiation Transfer Codes: Application to the Edge-On Disk of Gomez's Hamburger

, 2008
We have modeled optical to far infrared images, photometry, and spectroscopy of the object known as Gomez's Hamburger. We reproduce the images and spectrum with an edge-on disk of mass 0.3M_sun and radius 1600AU, surrounding an A0 III star at a distance ...

Photoluminescent UV Light Modulation via Anisometric Carbon Nanodots for UV–Visible Shutter and UV Sensor

Advanced Functional Materials, EarlyView.
Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Olivine’s high radiative conductivity increases slab temperature by up to 200K

Nature Communications
The thermal evolution of slabs governs their subduction dynamics and the transport of water into Earth’s interior. However, current slab subduction models often neglect the contribution of radiative thermal conductivity (i.e., heat transport by light ...

Revised Line Profile Function for Hydrogenic Species

Open Astronomy, 2012
Analytical series expansions for the hydrogenic spectral line profile functions are derived starting from the three single expressions, obtained by integrating twice the convolution of the Holtsmark, Lorentz and Doppler line profile functions.

Heavy Quark Radiative Energy Loss in QCD Matter

, 2003
Heavy quark medium induced radiative energy loss is derived to all orders in opacity, $(L/\lambda_g)^n$. The analytic expression generalizes the GLV opacity expansion for massless quanta to heavy quarks with mass $M$ in a QCD plasma with a gluon ...
