Chemo-dynamical Simulations and Galactic Archaeology [PDF]

AIP Conference Proceedings, 2010
We predict the frequency distribution of elemental abundance ratios from Carbon to Zinc as a functions of time location, which can be directly compared with the next generation of the galactic archeology project such as the HERMES. We perform the chemodynamical simulations of a Milky Way‐type galaxy from a CDM initial condition, using a self‐consistent

Scaling K2. VI. Reduced Small-planet Occurrence in High-galactic-amplitude Stars

The Astronomical Journal, 2023
In this study, we performed a homogeneous analysis of the planets around FGK dwarf stars observed by the Kepler and K2 missions, providing spectroscopic parameters for 310 K2 targets —including 239 Scaling K2 hosts—observed with Keck/HIRES.

Galactic Archaeology and Minimum Spanning Trees [PDF]

, 2015
Chemical tagging of stellar debris from disrupted open clusters and associations underpins the science cases for next-generation multi-object spectroscopic surveys. As part of the Galactic Archaeology project TraCD (Tracking Cluster Debris), a preliminary attempt at reconstructing the birth clouds of now phase-mixed thin disk debris is undertaken using

Asteroseismology for Galactic archaeology: bridging two fields [PDF]

Proceedings of the International Astronomical Union, 2015
AbstractAsteroseismology has the capability of precisely determining stellar properties that would otherwise be inaccessible, such as radii, masses, and thus ages of field stars. When coupling this information with classical determinations of stellar parameters, such as metallicities, effective temperatures, and angular diameters, powerful new ...

PLATO as it is: A legacy mission for Galactic archaeology [PDF]

Astronomische Nachrichten, 2017
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high‐resolution chrono‐chemo‐kinematical maps of the Galaxy. Data from large‐scale astrometric and spectroscopic surveys will soon provide us with a well‐defined view of the current chemo‐kinematical structure of the Milky Way, but it ...

Model Choice Matters for Age Inference on the Red Giant Branch

The Astrophysical Journal
Galactic archaeology relies on accurate stellar parameters to reconstruct the Galaxy's history, including information on stellar ages. While the precision of data has improved significantly in recent years, stellar models used for age inference have not ...

Recovery From Anorexia Nervosa: A Concept Analysis

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim Despite decades of research, we still know surprisingly little about how best to bring about lasting recovery from anorexia nervosa (AN). Furthermore, there is a lack of consensus in the research and treatment communities about what constitutes recovery from AN, or whether “recovery” is even an appropriate term to use in this context.

Minor epic: Notes toward a different “Anthropoetry”

Anthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival
