Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ

Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26

We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…

The Stellar Observations Network Group (SONG) -- A Legacy Archive of Stellar Time-Domain Spectroscopy

M. N. Lund, F. Grundahl, M. S. Fredslund +41

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…

Granulation signatures as seen by Kepler short-cadence data. I. A decoupling between granulation and oscillation timescales for dwarfs

Jens R. Larsen, Mia S. Lundkvist, Martin B. Nielsen +3

Granulation is the observable signature of convection in envelopes of low-mass stars, forming the background in stellar power spectra. While well-studied in evolved giants, granula…

Asteroseismology of solar-like oscillators: emulating individual mode frequencies with a branching neural network

Owen J. Scutt, Guy R. Davies, Amalie Stokholm +6

Accurately measuring stellar ages and internal structures is challenging, but the inclusion of asteroseismic observables can substantially improve precision. However, the curse of…

Investigating magnetic activity cycles in solar-like oscillators using asteroseismic data from the K2 mission

Gleb Berloff, Anne-Marie Broomhall, George T. Hookway +3

We present the results of an investigation into the possible presence of magnetic activity cycles in stars observed in two observational campaigns by the K2 mission. This study was…

Peakbagging the K2 KEYSTONE sample with PBjam: characterising the individual mode frequencies in solar-like oscillators

George T. Hookway, Martin B. Nielsen, Guy R. Davies +5

The pattern of individual mode frequencies in solar-like oscillators provides valuable insight into their properties and interior structures. The identification and characterisatio…
