NGC 1901: A new benchmark cluster for gyrochronology in the TESS Southern continuous viewing zone
Mara Bernizzoni, Timothy R. Bedding, Prasad Mani +5
We use Gaia DR3 astrometry and TESS time-series photometry to study NGC 1901, a sparse open cluster in the TESS Southern continuous viewing zone, that has been neglected due to its…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Star-Planet Interactions: The Instrumentation Perspective
H. Korhonen, P. Figueira, B. Montet +4
Star-Planet Interactions (SPIs) produce observable phenomena across the electromagnetic spectrum, from X-ray and ultraviolet emission tracing magnetic activity and atmospheric esca…
Star-Planet Interactions: Observational Techniques and Methods
P. Figueira, H. Korhonen, A. Buccino +8
This chapter summarizes the techniques and methods used to study star-planet interaction (SPI) from the observational point of view. SPI can produce a wide range of observational s…
TESS Observations of Stochastic Low-frequency Variability in Extreme Helium Stars
Courtney L. Crawford, C. Simon Jeffery, May G. Pedersen +4
Extreme helium stars (EHes) are low-mass hydrogen-deficient stars thought to be the products of double white dwarf mergers. Despite prolonged ground-based observations, there is no…
Testing Red Clump Models with the Asteroseismic Binary KIC 10841730
Lea S. Schimak, Timothy R. Bedding, Courtney L. Crawford +9
Binaries in which both stars are pulsating are rare but extremely valuable. We present the first study of an asteroseismic binary system consisting of a core helium-burning red clu…
