Magnetohydrostatic modelling of stellar coronae [PDF]

, 2016
We introduce to the stellar physics community a method of modelling stellar coronae that can be considered to be an extension of the potential field. In this approach, the magnetic field is coupled to the background atmosphere.

Asteroseismology of High-Mass Stars: New Insights of Stellar Interiors With Space Telescopes

Frontiers in Astronomy and Space Sciences, 2020
Massive stars are important metal factories in the Universe. They have short and energetic lives, and many of them inevitably explode as a supernova and become a neutron star or black hole.

Revealing the Galaxy–Halo Connection through Machine Learning

The Astrophysical Journal, 2023
Understanding the connections between galaxy stellar mass, star formation rate, and dark matter halo mass represents a key goal of the theory of galaxy formation. Cosmological simulations that include hydrodynamics, physical treatments of star formation,

The Physics of Stellar Interiors

, 2022
These are the slides for a seminar talk that I gave on August 9, 2022 as part of the Space Science and Security Summer Seminar Series at Lawrence Livermore National Laboratory.  The talk gives an overview of some aspects of stellar hydrodynamics, and describes how realistic hydrodynamic simulations are used to improve stellar structure and evolution ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Atomic and Molecular Data for Stellar Physics: Former Successes and Future Challenges [PDF]

, 2003
This review highlights current (and future) hot topics in astrophysics where atomic or molecular input data are (or will be) essential, with special emphasis on topics relating to nucleosynthesis and cosmochemistry.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

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

EPJ 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.

The atmosphere of supergiant star HD 7927 (F0 Ia): Fundamental parameters and chemical composition [PDF]

Serbian Astronomical Journal
The atmosphere of supergiant star HD 7927 (F0 Ia) is investigated by the method of atmospheric model. The effective temperature and surface gravity are determined by comparing the observed and theoretical values of photometrical indices ...
