Low-dimensional lonely branching random walks die out [PDF]
arXiv, 2017 The lonely branching random walks on ${\mathbb Z}^d$ is an interacting particle system where each particle moves as an independent random walk and undergoes critical binary branching when it is alone. We show that if the symmetrized walk is recurrent, lonely branching random walks die out locally.

Blue Stragglers After the Main Sequence
, 2008 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases.

Law of large numbers for supercritical superprocesses with non-local branching [PDF]
arXiv, 2018 In this paper we establish a weak and a strong law of large numbers for supercritical superprocesses with general non-local branching mechanisms. Our results complement earlier results obtained for superprocesses with only local branching. Several interesting examples are developed, including multitype continuous-state branching processes, multitype ...

From the atmosphere to the circumstellar environment in cool evolved stars
, 2014 We discuss and illustrate contributions that optical interferometry has made on our current understanding of cool evolved stars. We include red giant branch (RGB) stars, asymptotic giant branch (AGB) stars, and red supergiants (RSGs).

PSR J1947−1120: A New Huntsman Millisecond Pulsar Binary
The Astrophysical JournalWe present the discovery of PSR J1947–1120, a new huntsman millisecond pulsar with a red giant companion star in a 10.3 day orbit. This pulsar was found via optical, X-ray, and radio follow-up of the previously unassociated γ -ray source 4FGL J1947.6 ...

Asteroseismology with TESS: Emergence of Dipole Mode Suppression from Subgiants?
The Astrophysical JournalDipole mode suppression is an observed behavior of solar-like oscillations in evolved stars. This study aims to search for depressed dipole modes in giant stars using data from the Transiting Exoplanet Survey Satellite (TESS) and investigate when the ...

Selected topics in the evolution of low-mass stars
EPJ Web of Conferences, 2013 Low-mass stars play a key role in many different areas of astrophysics. In this article, I provide a brief overview of the evolution of low-mass stars, and discuss some of the uncertainties and problems currently affecting low-mass stellar models ...

Uncovering Branch specialization in InceptionV1 using k sparse autoencoders [PDF]
arXivSparse Autoencoders (SAEs) have shown to find interpretable features in neural networks from polysemantic neurons caused by superposition. Previous work has shown SAEs are an effective tool to extract interpretable features from the early layers of InceptionV1.
