ROSAT HRI observations of the globular clusters M13 and M92 [PDF]

, 1996
We report on 40 kiloseconds of ROSAT HRI observations of the globular cluster M92 (NGC 6341) and 20 kiloseconds of observations of the globular cluster M13 (NGC 6205).

Constraints on the distance moduli, helium and metal abundances, and ages of globular clusters from their RR Lyrae and non-variable horizontal-branch stars. II. Multiple stellar populations in 47Tuc, M3, and M13

, 2017
We present a new set of horizontal-branch (HB) models computed with the MESA stellar evolution code. The models adopt $\alpha$-enhanced \cite{ags09} metals mixtures and include the gravitational settling of He.

The Role of Thermohaline Mixing in Intermediate- and Low-Metallicity Globular Clusters

, 2012
It is now widely accepted that globular cluster red giant branch stars owe their strange abundance patterns to a combination of pollution from progenitor stars and in situ extra mixing.

Revisiting the role of the Thermally-Pulsating Asymptotic Giant Branch phase in high-redshift galaxies [PDF]

, 2015
We study the debated contribution from thermally pulsing asymptotic giant branch (TP-AGB) stars in evolutionary population synthesis models. We investigate the Spectral Energy Distributions (SEDs) of a sample of 51 spectroscopically confirmed, high-z ($1.

Formal and informal social care in people with Rheumatic and Musculoskeletal diseases: a cross‐sectional multicentre survey

Arthritis Care &Research, Accepted Article.
Introduction Rheumatic and musculoskeletal diseases(RMDs) are leading causes of physical disability, necessitating support with activities of daily living(ADLs). This study describes social care received by patients with RMDs in two disperate regions of England: Salford(urban) and Norfolk(rural).

The Spectra of Main Sequence Stars in Galactic Globular Clusters II. CH and CN Bands in M71 [PDF]

, 1999
Spectra with a high signal-to-noise ratio of 79 stars which are just below the main sequence turnoff of M71 are presented. They yield indices for the strength of the G band of CH and the ultraviolet CN band at 3885 \AA.
