The Complexity of the Cetus Stream Unveiled from the Fusion of STREAMFINDER and StarGO
Zhen Yuan, Khyati Malhan, Federico Sestito +16
We combine the power of two stream-searching tools, STREAMFINDER and StarGO applied to the Gaia EDR3 data, to detect stellar debris belonging to the Cetus stream system that forms…
High-precision chemical abundances of Galactic building blocks. The distinct chemical abundance sequence of Sequoia
Tadafumi Matsuno, Helmer H. Koppelman, Amina Helmi +5
Context: Sequoia is a retrograde kinematic substructure in the nearby Galactic halo, whose properties are a matter of debate. For example, previous studies do not necessarily agree…
Dynamically Tagged Groups of Metal-Poor Stars from the Best \& Brightest Survey
Derek Shank, Timothy C. Beers, Vinicius M. Placco +9
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for metal-poor stars ([Fe/H] ) compiled from the Best B…
The Pristine Dwarf-Galaxy survey -- IV. Probing the outskirts of the dwarf galaxy Boötes I
Nicolas Longeard, Pascale Jablonka, Anke Arentsen +12
We present a new spectroscopic study of the dwarf galaxy Bootes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Fi…
Disruption of Hierarchical Clustering in the Vela OB2 Complex and the Cluster Pair Collinder 135 and UBC7 with Gaia EDR3: Evidence of Supernova Quenching
Xiaoying Pang, Zeqiu Yu, Shih-Yun Tang +4
We identify hierarchical structures in the Vela OB2 complex and the cluster pair Collinder 135 and UBC 7 with Gaia EDR3 using the neural network machine learning algorithm StarGO.…
Evidence of a dwarf galaxy stream populating the inner Milky Way Halo
Khyati Malhan, Zhen Yuan, Rodrigo Ibata +3
Stellar streams produced from dwarf galaxies provide direct evidence of the hierarchical formation of the Milky Way. Here, we present the first comprehensive study of the "LMS-1" s…
