The Pristine survey -- XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations
R. Lucchesi, C. Lardo, P. Jablonka +14
We present a one-dimensional, local thermodynamic equilibrium (1D-LTE) homogeneous analysis of 132 stars observed at high-resolution with ESPaDOnS. This represents the largest samp…
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…
Rapid contraction of giant planets orbiting the 20 million-years old star V1298 Tau
A. Suárez Mascareño, M. Damasso, N. Lodieu +41
Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about…
The Pristine survey XIV: chemical analysis of two ultra-metal-poor stars
C. Lardo, L. Mashonkina, P. Jablonka +15
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultr…
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…
VVV-WIT-08: the giant star that blinked
Leigh C. Smith, Sergey E. Koposov, Philip W. Lucas +11
We report the serendipitous discovery of a late-type giant star that exhibited a smooth, eclipse-like drop in flux to a depth of 97 per cent. Minimum flux occurred in April 2012 an…
