Ensemble asteroseismology: An ensemble approach to detecting signatures of solar-like oscillations in K-dwarfs
William J. Chaplin, Tiago L. Campante, Mikkel N. Lund +5
Solar-like oscillations have to date been observed in hundreds of main-sequence and sub-giant stars. However, only a handful of detections have been made in K-type dwarfs, using gr…
gr8stars II : judgement day for spectroscopic parameter model systematics
Alix Violet Freckelton, Annelies Mortier, Megan Bedell +18
Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters truly reflect all b…
Granulation signatures as seen by Kepler short-cadence data. II. A hierarchical route to inferring stellar radii from granulation
Jens R. Larsen, Mia S. Lundkvist, Guy R. Davies +1
Stellar granulation arises from near-surface convection and is imprinted in stellar photometric time series, yet links between granulation observables and fundamental stellar prope…
Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. García, S. Mathur, G. T. Hookway +31
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity…
Assessment of PLATO Science Performance
Juan Cabrera, Heike Rauer, Reza Samadi +121
The PLATO mission is scheduled for launch early 2027. In this paper we present an overview of the performance drivers for the mission at the time where all flight models of the cam…
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…
