Multiple Populations in Low-mass Globular Clusters: Palomar 13 [PDF]
Astrophysical Journal, 2020 Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important, given that chemical inhomogeneity is found in almost all globular clusters.

Galactic AGB stars from the IPHAS survey [PDF]
, 2009 The INT Photometric H-Alpha Survey (IPHAS) is particular effective in tracing asymptotic giant branch (AGB) stars across the Galactic disk due to its use of broad-band r' and i' filters, and the clear separation of the dwarf and giant branches in the ...

Carbon-enhanced metal-poor stars: a window on AGB nucleosynthesis and binary evolution - I. Detailed analysis of 15 binary stars with known orbital periods [PDF]
, 2015 AGB stars are responsible for producing a variety of elements, including carbon, nitrogen, and the heavy elements produced in the slow neutron-capture process (s-elements).

Globular cluster chemistry in fast rotating dwarf stars belonging to intermediate age open clusters [PDF]
, 2018 (shortened) The peculiar chemistry observed in the multiple populations of Galactic globular clusters is not generally found in other systems like dwarf galaxies and open clusters, and at the moment no model can fully explain its presence.

Seventeen 2 Micron All Sky Survey (2MASS) Hypervelocity Stars (HVS) from Gaia DR3 [PDF]
Research Notes of the AASAs part of an ongoing search for hypervelocity stars I found seventeen two micron all sky survey sources with Gaia G magnitudes less than 16.0 and radial velocities less than −600 km s−1.

Massive binaries and the enrichment of the interstellar medium in globular clusters [PDF]
, 2009 Abundance anomalies observed in globular cluster stars indicate pollution with material processed by hydrogen burning. Two main sources have been suggested: asymptotic giant branch stars and massive stars rotating near the break-up limit.

Dynamical detection of three triple stellar systems in open clusters [PDF]
, 2014 We present a kinematic analysis of three triple stellar systems belonging to two open clusters: CPD-60{\deg}961 and HD66137 in NGC2516, and HD315031 in NGC6530.

A chemically peculiar post-AGB star in the Small Magellanic Cloud
, 2016 Post-Asymptotic Giant Branch (post-AGB) stars bear signatures of the entire chemical and morphological changes that occur prior to and during the AGB phase of evolution. These objects also provide vital clues on the ultimate fate of the star.
