Exploring Giant Barium Stars:12C/13C Ratio and Elemental Abundances of Carbon, Nitrogen, and Oxygen

The Astronomical Journal
Barium (Ba) stars belong to binary systems that underwent mass-transfer events. As a consequence, their envelopes were enriched with material synthesized in the interiors of their evolved companions via slow neutron-capture nucleosynthesis, the s ...

Abundances of neutron-capture elements in G 24-25. A halo-population CH subgiant

, 2012
The differences between the neutron-capture element abundances of halo stars are important to our understanding of the nucleosynthesis of elements heavier than the iron group.

The first Delta a observations of three globular clusters [PDF]

, 2014
Globular clusters are main astrophysical laboratories to test and modify evolutionary models. Thought to be rather homogeneous in their local elemental Distribution of members, results suggest a wide variety of chemical peculiarities.

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Probing Binary Architectures of Lithium-rich Giants in GALAH with COSMIC and Stellar Models

The Astrophysical Journal
Surface lithium is depleted when a star goes through the first dredge-up phase, yet 1% of red giants are found to be Li rich. The formation mechanism for these remains uncertain. We combine observational constraints from Galactic Archaeology with HERMES (

Reprocessing the Hipparcos data for evolved giant stars II. Absolute magnitudes for the R-type carbon stars [PDF]

, 2001
The Hipparcos Intermediate Astrometric Data for carbon stars have been reprocessed using an algorithm which provides an objective criterion for rejecting anomalous data points and constrains the parallax to be positive.
