The Aarhus Red Giants Challenge I: Stellar structures in the red giant branch phase
V. Silva Aguirre, J. Christensen-Dalsgaard, S. Cassisi +23
(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
From the bulge to the outer disc: StarHorse stellar parameters, distances, and extinctions for stars in APOGEE DR16 and other spectroscopic surveys
A. B. A. Queiroz, F. Anders, C. Chiappini +27
We combine high-resolution spectroscopic data from APOGEE-2 Survey Data Release 16 (DR16) with broad-band photometric data from several sources, as well as parallaxes from {\it Gai…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Insights from the APOKASC Determination of the Evolutionary State of Red-Giant Stars by consolidation of different methods
Yvonne Elsworth, Saskia Hekker, Jennifer A. Johnson +10
The internal working of low-mass stars is of great significance to both the study of stellar structure and the history of the Milky Way. Asteroseismology has the power to directly…
TESS Asteroseismology of the known red-giant host stars HD 212771 and HD 203949
Tiago L. Campante, Enrico Corsaro, Mikkel N. Lund +45
The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables…
Chronos --- Taking the pulse of our Galactic neighbourhood (ESA Voyage 2050 White Paper)
Eric Michel, Kévin Belkacem, Benoît Mosser +13
The period 2035-50 considered in the ESA Voyage long-term plan will coincide with a series of foreseeable advances in the characterization of the stellar content of the Milky Way.…
