On compressive radial tidal forces

open access: yes, 2007
Radial tidal forces can be compressive instead of disruptive, a possibility that is frequently overlooked in high level physics courses. For example, radial tidal compression can emerge in extended stellar systems containing a smaller stellar cluster ...

Is there a mass discrepancy in the Cepheid binary OGLE-LMC-CEP0227? [PDF]

open access: yes, 2011
Context. The Cepheid mass discrepancy, the difference between masses predicted from stellar evolution and stellar pulsation calculations, is a challenge for the understanding of stellar astrophysics. Recent models of the eclipsing binary Cepheid OGLE-LMC-

Stellar Evolution Models of Young Stars: Progress and Limitations

open access: yes, 2015
Stellar evolution models are a cornerstone of young star astrophysics, which necessitates that they yield accurate and reliable predictions of stellar properties.

Uncertainties in AGB Evolution and Nucleosynthesis

open access: yes, 2016
We summarise the evolution and nucleosynthesis in AGB and Super-AGB stars. We then examine the major sources of uncertainty, especially mass-loss.Comment: 8 pages, no figures.

Constraining stellar physics from red-giant stars in binaries – stellar rotation, mixing processes and stellar activity

open access: yesEPJ Web of Conferences, 2017
The unparalleled photometric data obtained by NASA’s Kepler Space Telescope has led to an improved understanding of stellar structure and evolution - in particular for solar-like oscillators in this context. Binary stars are fascinating objects.

$\alpha$ Centauri A as a potential stellar model calibrator: establishing the nature of its core

open access: yes, 2018
Understanding the physical process responsible for the transport of energy in the core of $\alpha$ Centauri A is of the utmost importance if this star is to be used in the calibration of stellar model physics.

Fifty Years After the Discovery of the First Stellar-Mass Black Hole: A Review of Cyg X-1

open access: yesGalaxies
Around 50 years ago, the famous bet between Stephen Hawking and Kip Thorne on whether Cyg X-1 hosts a stellar-mass black hole became a well-known story in the history of black hole science.

The Impact of Rotation on the Evolution of Low-Mass Stars

open access: yes, 2007
High precision photometry and spectroscopy of low-mass stars reveal a variety of properties standard stellar evolution cannot predict. Rotation, an essential ingredient of stellar evolution, is a step towards resolving the discrepancy between model ...

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).
