Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk
Anya Dovgal, Kim A. Venn, Federico Sestito +31
Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…
SPLUS J142445.34-254247.1: An R-Process Enhanced, Actinide-Boost, Extremely Metal-Poor star observed with GHOST
Vinicius M. Placco, Felipe Almeida-Fernandes, Erika M. Holmbeck +33
We report on the chemo-dynamical analysis of SPLUS J142445.34-254247.1, an extremely metal-poor halo star enhanced in elements formed by the rapid neutron-capture process. This sta…
ExoGemS High-Resolution Transmission Spectroscopy of WASP-76b with GRACES
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +9
We present high-resolution transmission spectroscopy of WASP-76b with GRACES/Gemini North obtained as part of the ExoGemS survey. With a broad spectral range of 400-1050 nm and a r…
ExoGemS Detection of a Metal Hydride in an Exoplanet Atmosphere
Laura Flagg, Jake D. Turner, Emily Deibert +7
Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs. However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in exoplan…
Homogeneous search for helium in the atmosphere of 11 gas giant exoplanets with SPIRou
R. Allart, P. -B. Lemée-Joliecoeur, A. Y. Jaziri +31
The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass…
Keck, Gemini, and Palomar 200-inch visible photometry of red and very-red Neptunian Trojans
B. T. Bolin, C. Fremling, A. Morbidelli +9
Neptunian Trojans (NTs), trans-Neptunian objects in 1:1 mean-motion resonance with Neptune, are generally thought to have been captured from the original trans-Neptunian protoplane…
