Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
The Global Dynamical Atlas of the Milky Way mergers: Constraints from Gaia EDR3 based orbits of globular clusters, stellar streams and satellite galaxies
Khyati Malhan, Rodrigo A. Ibata, Sanjib Sharma +7
The Milky Way halo was predominantly formed by the merging of numerous progenitor galaxies. However, our knowledge of this process is still incomplete, especially in regard to the…
A stellar stream remnant of a globular cluster below the metallicity floor
Nicolas F. Martin, Kim A. Venn, David S. Aguado +23
Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures formed in the early un…
Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
Jaclyn Jensen, Guillaume Thomas, Alan W. McConnachie +9
We examine the spatial clustering of blue horizontal branch (BHB) stars from the -band of the Canada-France Imaging Survey (CFIS, a component of the Ultraviolet Near-In…
The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
