Milky Way's warped disc traced by AGB stars
Tanya Kushwahaa, Mikako Matsuura, Jason A. S. Hunt +3
While the presence of the Galactic warp has long been established from observations of \HI\, gas, the \textit{Gaia} measurements of over 1 billion stars with parallaxes have enable…
Towards Galactic Archaeology with Inferred Ages of Giant Stars From Gaia Spectra
Aisha S. Almannaei, Daisuke Kawata, Ioana Ciuca +4
In the era of Gaia, the accurate determination of stellar ages is transforming Galactic archaeology. We demonstrate the feasibility of inferring stellar ages from Gaia's RVS spectr…
Investigating the eccentricity distribution of transiting, long-period giant planets
Ahlam Alqasim, Teruyuki Hirano, Yasunori Hori +12
Eccentric giant planets are predicted to have acquired their eccentricity through two major mechanisms: the Kozai-Lidov effect or planet-planet scattering, but it is normally diffi…
A link between rocky exoplanet composition and stellar age
Angharad Weeks, Vincent Van Eylen, Daniel Huber +7
Interior compositions are key for our understanding of Earth-like exoplanets. The composition of the core can influence the presence of a magnetic dynamo and the strength of gravit…
