The Stellar Observations Network Group (SONG) -- A Legacy Archive of Stellar Time-Domain Spectroscopy
M. N. Lund, F. Grundahl, M. S. Fredslund +35
The Stellar Observations Network Group (SONG) network has operated for more than a decade, providing long-baseline, high-cadence spectroscopic observations of bright stars and the…
Asteroseismic Analysis of the Merger Product Red Giant in the Persei System
Rozália Z. Ãdám, László Molnár, Róbert Szabó +7
Context. Persei is a long-period eclipsing binary system ( years) containing a red giant primary, and it is well known for its multi-faceted classification as a…
Luminaries in the Sky: The TESS LEGACY sample of bright stars. II. In-depth seismic characterisation of 32 naked-eye stars in the PLATO LOP fields
E. Panetier, G. T. Hookway, E. Corsaro +13
The NASA TESS mission is conducting a nearly full-sky survey, enabling the photometric characterisation of millions of stars. The forthcoming ESA PLATO mission will provide long-du…
The Pan-Pacific Planet Search -- IX. A menagerie of companions orbiting evolved stars
Robert A. Wittenmyer, Alexander Venner, Tyler Fairnington +22
We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey…
The Herculis system solved after nearly three centuries
Marcus L. Marcussen, Mikkel N. Lund, Frank Grundahl +11
Herculis is a bright, nearby quadruple system. Its brightest member, Her Aa, displays solar-like oscillations, establishing the system as a crucial benchmark for asterose…
Glitch analysis and asteroseismic modelling of subgiant Herculis: confirming and interpreting the peak as the helium glitch
Advik Gupta, Kuldeep Verma, Hans Kjeldsen +7
The measurements of pressure-mode and mixed-mode oscillation frequencies in subgiant stars offer a unique opportunity to probe their internal structures -- from the surface to the…
