Journal Article
Durfeldt-Pedros, O., Antoci, V., Smalley, B., Murphy, S., Posilek, N., & Niemczura, E. (2024). Variability and stellar pulsation incidence in Am/Fm stars using TESS and Gaia data. Astronomy and Astrophysics, 690, Article A104. https://doi.org/10.1051/0004-6361/202349076

Aims. We aim to study chemically peculiar Am and Fm stars, distinguished by their unique abundance patterns, which are crucial for studying mixing processes in intermediate-mass stars. These stars provide a window into the atomic diffusion in their s... Read More about Variability and stellar pulsation incidence in Am/Fm stars using TESS and Gaia data.

Background
Remote and digital consulting in primary care has rapidly expanded since March 2020. It is important to understand patient experiences, particularly for those living with complex long-term conditions, to identify how care can best be deli...
