Solar cycle variation of in helioseismic data and its implications for asteroseismology
Rachel Howe, William J. Chaplin, Sarbani Basu +7
The frequency, , at which the envelope of pulsation power peaks for solar-like oscillators is an important quantity in asteroseismology. We measure for t…
Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi
William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81
Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
Measurement of atmospheric scintillation during a period of Saharan dust (Calima) at Observatorio del Teide, Izaña, Tenerife, and the impact on photometric exposure times
S J Hale, W J Chaplin, G R Davies +3
We present scintillation noise profiles captured at the Observatorio del Teide, Izaña, Tenerife, over a one-week period in September 2017. Contemporaneous data from the Birmingham…
Asteroseismic constraints on active latitudes of solar-type stars: HD173701 has active bands at higher latitudes than the Sun
Alexandra E. L. Thomas, William J. Chaplin, Guy R. Davies +6
We present a new method for determining the location of active bands of latitude on solar-type stars, which uses stellar-cycle-induced frequency shifts of detectable solar-like osc…
A Distant Mirror: Solar Oscillations Observed on Neptune by the Kepler K2 Mission
P. Gaulme, J. F. Rowe, T. R. Bedding +24
Starting in December 2014, Kepler K2 observed Neptune continuously for 49 days at a 1-minute cadence. The goals consisted of studying its atmospheric dynamics (Simon et al. 2016),…
Parametrizing the time-variation of the "surface term" of stellar p-mode frequencies: application to helioseismic data
R. Howe, S. Basu, G. R. Davies +4
The solar-cyle variation of acoustic mode frequencies has a frequency dependence related to the inverse mode inertia. The discrepancy between model predictions and measured oscilla…
