Predicting the Kinematics of the Cold Circumgalactic Medium from its Morphology using Convolutional Neural Networks
Connor Jennings, Earl P. Bellinger, Imad Pasha +2
We present a novel approach to predicting plane-of-sky velocities of cold gas clouds in the circumgalactic medium (CGM) of galaxies. The method uses a convolutional neural network…
\texttt{calypso}: a Parameter-Conditioned Stochastic Surrogate Model for Circumbinary Accretion Time-Series
Magdalena Siwek, Matt Ho, Earl Bellinger
We present calypso, a parameter-conditioned stochastic surrogate model for circumbinary accretion flows. We represent the total and individual accretion time series in a PCA basis…
The sensitivity and behaviour of the curvature in the échelle diagram of red-giant stars
S. Hekker, Y. Elsworth, S. Basu +5
In the convective envelopes of relatively cool stars, oscillations are excited by turbulent convection. In these so-called solar-like oscillators, radial oscillation modes appear a…
Self-Consistent Nonlinear Classical Cepheid Pulsations During Stellar Evolution with MESA
Ebraheem Farag, Earl P. Bellinger, Philip Mocz +5
We extend the time-dependent convection treatment in \code{MESA} by introducing eddy-viscous damping. This software change brings \code{MESA-TDC} into closer alignment with the rad…
Red-Giant Asteroseismology of Low-Mass Population III Stars
Thiago Ferreira, Earl P. Bellinger, Ebraheem Farag +1
Low-mass stars from the first epoch of star formation may still persist in the Milky Way and its satellite dwarf galaxies today; however, their detection is confounded by surface p…
Evolution of Low-Mass Population III Stars: Convection, Mass Loss, Nucleosynthesis, and Neutrinos
Thiago Ferreira, Earl P. Bellinger, Ebraheem Farag +1
The first stars likely formed from pristine clouds, marking a transformative epoch after the dark ages by initiating reionisation and synthesising the first heavy elements. Among t…
