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…
Asteroseismic ages for 17,000 stars in Kepler, K2 and TESS
Emma Willett, Andrea Miglio, Saniya Khan +9
The availability of asteroseismic constraints for tens of thousands of red giant (RG) stars has opened the door to robust age estimates, enabling time-resolved studies of different…
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…
Bolometric corrections of stellar oscillation mode amplitudes as observed by the PLATO mission. I. Planck-spectrum estimates
Mikkel N. Lund, Jérôme Ballot, William J. Chaplin
We derive bolometric correction functions for oscillation mode amplitudes observed by the different cameras of the ESA PLATO mission. Such corrections between bolometric (full ligh…
Optimising the global detection of solar-like oscillations. Tuning the frequency range for asteroseismic detection predictions and searches
Mikkel N. Lund, William J. Chaplin
A well-established method exists for predicting the detectability of solar-like oscillations and has been widely used to support target selection for space-based photometric missio…
Constraints on sunspot group lifetimes from far-side Sun-as-a-star helioseismology with BiSON
William J. Chaplin, Rachel Howe, Sarbani Basu +5
Frequencies of low-degree solar p modes are sensitive to activity over the entire Sun, including the unobservable far-side hemisphere. When frequency shifts extracted from week-lon…
