Evolution and Nucleosynthesis of AGB stars in Three Magellanic Cloud Clusters

, 2011
We present stellar evolutionary sequences for asymptotic giant branch (AGB) stars in the Magellanic Cloud clusters NGC 1978, NGC 1846 and NGC 419. The new stellar models for the three clusters match the observed effective temperatures on the giant ...

Nonradial, nonadiabatic stellar pulsations

The Astrophysical Journal, 1990
This paper describes how nonradial stellar pulsations can be modeled using a Lagrangian formulation. The adiabatic eigenvalues of this operator are compared to previously published results, using simple stellar models to show the equivalence of this method and other techniques.

Prediction of Myasthenia Gravis Worsening: A Machine Learning Algorithm Using Wearables and Patient‐Reported Measures

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myasthenia gravis (MG) is a rare disorder characterized by fluctuating muscle weakness with potential life‐threatening crises. Timely interventions may be delayed by limited access to care and fragmented documentation. Our objective was to develop predictive algorithms for MG deterioration using multimodal telemedicine data ...

Dance to Demise—How Massive Stars May Form Dense Circumstellar Shells before Explosion

The Astrophysical Journal
We investigate the evolution of red supergiant (RSG) progenitors of core-collapse supernovae (SNe) with initial masses between 12 and 20 M _⊙ , focusing on the effects of enhanced mass loss due to pulsation-driven instabilities in their envelopes and ...

Reduced Muscular Carnosine in Proximal Myotonic Myopathy—A Pilot 1H‐MRS Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Myotonic dystrophy type 2 (proximal myotonic myopathy, PROMM) is a progressive multisystem disorder with muscular symptoms (proximal weakness, pain, myotonia) and systemic manifestations such as diabetes mellitus, cataracts, and cardiac arrhythmias.

Cepheid limb darkening, angular diameter corrections, and projection factor from static spherical model stellar atmospheres

, 2012
Context. One challenge for measuring the Hubble constant using Classical Cepheids is the calibration of the Leavitt Law or period-luminosity relationship.

Refractory Status Epilepticus Treated With Bilateral Pulvinar Deep Brain Stimulation—A Case Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT New‐onset refractory status epilepticus (NORSE) arises without an identifiable cause or prior epilepsy history, with a 16%–27% mortality rate and significant long‐term neurological sequelae. Neuromodulation such as deep brain stimulation (DBS) targeting the anterior and centromedian thalamic nuclei has shown promise when the traditional ...

IS POLARIS LEAVING THE CEPHEID INSTABILITY STRIP?

Odessa Astronomical Publications, 2017
Although Polaris is generally regarded as an overtone pulsator that may soon switch to pulsation in the fundamental mode, it is argued that the variable is actually crossing the instability strip for the first time and is in the process of leaving the ...

Constraining the near-core rotation of the gamma Doradus star 43 Cygni using BRITE-Constellation data

, 2017
Photometric time series of the $\gamma$ Dor star 43 Cyg obtained with the BRITE-Constellation nano-satellites allow us to study its pulsational properties in detail and to constrain its interior structure.

Some Remarks on Stellar Pulsation [PDF]

International Astronomical Union Colloquium, 2000
AbstractI wondered at first why I had been asked to perform the task of commenting on the scientific discussion of this meeting, until a member of the Scientific Organising Committee pointed out to me that I have not published a serious paper on the subject of the colloquium in his memory (I am not sure whether this is more a statement of the ...
