Starry messages: Searching for signatures of interstellar archaeology [PDF]
, 2009 Searching for signatures of cosmic-scale archaeological artifacts such as Dyson spheres or Kardashev civilizations is an interesting alternative to conventional SETI.

A Wave-corrected Assessment of the Local Midplane
The Astrophysical JournalAs the number of known Galactic structures mounts thanks to the Gaia Space Telescope, it is now pertinent to study methods for disentangling structures occupying the same regions of the Milky Way. Indeed, understanding the precise form of each individual

The evolution of the Galactic Disk in a New Era of Galactic Archaeology
L'évolution du disque galactique dans une nouvelle ère de l'archéologie galactique Dans l'univers actuel, une étoile a plus de chances de se trouver dans une galaxie semblable à la Voie lactée (VL) que dans tout autre type de galaxies, ce qui fait de notre galaxie un laboratoire idéal pour étudier les processus généraux qui dominent la ...

Galactic archaeology with the oldest stars in the Milky Way
, 2020 During a dark night, it is possible to observe thousands of stars by eye. All these stars are located within the Milky Way, our home. Not all stars are the same, they can have different sizes, masses, temperatures and ages. Heavy stars do not live long (in astronomical terms), only a few million years, but stars less massive than the Sun can get more ...

The power of chemical tagging for studying Galactic evolution
, 2015 Chemical tagging is a relatively new technique in Galactic Archaeology, designed to find unique stellar groups among the Galactic field stars. Each small galaxy accreted by a large galaxy like the Milky Way leaves its own tidal stream of debris which is

On the Origin of Neutron-capture Elements in r-I and r-II Stars: A Differential-abundance Analysis
The Astrophysical JournalWe present a strictly line-by-line differential analysis of a moderately r -process-enhanced star ( r -I: HD 107752) with respect to a strongly r -process-enhanced star ( r -II: CS 31082-0001) to investigate the possible common origin of their heavy ...

The Meridian S02E02 : Galactic archeology & ash on the mountain
, 2022 In the second episode of the second season Nic and Rebecca invite Diane Feuillet to the microphone. Diane is a researcher here at Lund Observatory working on galactic archaeology using stellar abundances, ages and kinematics. In this second season of the

The R-process Alliance: Enrichment of r-process Elements in a Simulated Milky Way–like Galaxy
The Astrophysical JournalWe study the formation of stars with varying amounts of heavy elements synthesized by the rapid neutron-capture process ( r -process) based on our detailed cosmological zoom-in simulation of a Milky Way–like galaxy with an N -body/smoothed particle ...

The chemical DNA of the Magellanic Clouds
Astronomy & AstrophysicsContext. In the context of galactic archaeology, the study of the Small Magellanic Cloud (SMC) is of crucial importance, as it represents a unique opportunity to study a nearby massive dwarf system.
